Tell us the truth
1997 February 20
A man stands in silence at the entrance to a makeshift courtroom,
he holds a placard showing a picture of Ayrton Senna and the
words "Tell us the truth" written underneath.
It is February 20 1997 in a converted ballroom at Imola, and
amid invasion by the world's media, the Ayrton Senna manslaughter
Judge Antonio Costanzo swiftly ordered the hordes of cameramen
and reporters out of the hall, allowing two fixed television
cameras to remain for the trial, but said they could not film
defendants who objected, including Williams and Patrick Head.
The only defendant present was Federico Bendinelli, director
of Sagis, the company that runs the Imola circuit. He told reporters
that in Italy criminal investigations are obligatory and added
that no-one should be held responsible for the accident.
Bendinelli had said on Thursday that "Senna's death was
due exclusively to the fact that part of the suspension block
on one of the wheels snapped off and broke through his visor
hitting his forehead."
"It was like a bullet. If it were not for this, he (Senna)
could have walked away from the accident."
He also told the Rome daily newspaper La Republica:
"The risk exists that all races in Italian territory
will be banned if we are convicted."
A lawyer representing the Senna family was in attendance as
an observer, and stated that Senna's relatives would be following
the trial very closely, but had decided not to stand as civil
The Italian news agency reports that prosecutors accuse Williams
and others of manslaughter based on an inquiry which indicated
that Senna's steering column snapped, due to a faulty weld made
previously, when the car was modified to make it lighter.
Race officials are charged for not ensuring that safety requirements
Today's three hour session dealt mainly with preliminaries.
There was a defence challenge against the investigative procedures
of Maurizio Passarini, and a request that tests on the wrecked
car should be ignored because two defendants were not present
during the appraisals.
Lawyers said that much of the case against Newey and Bruynseraede,
which had built up over the past 3 years, should be ignored as
their clients were not informed of the inquiry, nor given the
opportunity to defend themselves.
"This is a scandal. It should not happen in a civilised
country," Newey's lawyer Luigi Stortoni told the court.
Oreste Dominioni, one of Williams' lawyers said "We are
absolutely sure the car was in good order. The steering column
broke after and not before the crash."
The prosecutor, Maurizio Passarini, said he planned to call
as witnesses world champion driver Damon Hill, Bernie Ecclestone,
head of FOCA (Formula One Constructors Association), and Michael
Schumacher, Ferrari driver.
The judge said witnesses would testify between April 24 and
This period will coincide with those people being in Italy
for the San Marino Grand Prix.
The trial resumes on February 28, when the presiding judge
will rule on various defence requests to limit evidence.
The prosecution will present its case on March 5, with the
first witness due to testify on March 12.

Legal blunder in Senna case?
1997 February 21
Luigi Stortoni, the lawyer acting for Adrian Newey (Williams
chief designer), stated in court that his client had been improperly
questioned by examining magistrate Maurizio Passarini in order
to obtain evidence.
He argued that Passarini had interviewed Newey as a witness,
not as an accused, and had failed to warn him that he (Newey)
could face prosecution.
Filippo Sgubbi, acting for Roland Bruynseraede (FIA official)
also claimed that his client gave information under similar circumstances.
Francesco Pintor (head prosecutor) maintained, "All the
rules and regulations were strictly adhered to."

Damon Hill's car also a death trap?
1997 February 23
"On the day that claimed the life of Ayrton Senna, Damon
Hill was driving a Williams-Renault which had been modified in
exactly the same way as the great Brazilian drivers".
This is a claim made in a British newspaper today.
The 'News of the World' reports:
The steering columns on the Williams-Renaults of Hill and
Senna were altered two months previously, in the SAME way on
the SAME day.
Williams will claim: Hill's car worked perfectly well, blaming
track debris as the most likely cause of Senna's accident.
Williams previously stated: Senna had asked for a modification
to lower his steering wheel, the steering column snapped AFTER
impact with the wall at Tamburello.
It took Maurizio Passarini over two years to collate the evidence
contained in a 3,000+ page report (reports as to the 'size'
of this document vary! Ed), which finally led to the indictment
of the six accused. The Italian prosecution's case maintains:
The accident was caused by the modified steering column, track
debris played no part.
The News of the World article quotes Professor Adolpho Melchionda,
a mechanical engineer, and member of the court's investigative
team, as saying:
"When you saw through an essential part of the machinery,
you are altering the crystalline structure of the metal involved.
This can work, on the other hand, may not work. To say that it
was a job well done, because Hill had no problems, is short-sighted."
"We believe that the evidence will show that he was driving
a potential death trap and was lucky nothing happened to him.
The cause of Senna's crash was the work done on the rod. The
*recent pictures which were released showing the scrap on the
track have nothing to do with it at all."
* The recent picture referred to was published by the British
'Sunday Times newspaper, just 4 days before the Senna manslaughter
trial began, in an article entitled:
"Photograph explains riddle of Ayrton Senna's death."
Sagis, the company which runs the Imola circuit, later
"The photo did not show the part of the circuit leading
into the final curve, but was some 700m from the Tamburello bend.
The photos and also video footage showing the debris were handed
over to the Italian magistrature immediately after the crash."
The S.T. article also alleged that: Senna may have "held
his breath and passed out." - Ed.
And continues: Newey's defence lawyer Luigi Stortoni, confirmed
the same work had been done on both Williams cars. He said:
"Work was done on the steering rod. The same work was
done on Hill's car. The diameters of the two pieces of pole were
different. But to demonstrate that the job was done well, it
has to be shown how Damon Hill had no trouble with his car."
"We are convinced that the welding was not the cause.
The work was done in March, and both Hill and Senna had raced
two Grand Prix with the modified cars and there wasn't any problem."
"On the third, Senna crashed. I don't know how many times,
if ever, Hill raced the modified car after that. And Newey certainly
did not carry out the work."
Newey is involved in a contract dispute with the Williams
team after agreeing to join McLaren from the year 2000.
Milan-based lawyer Oreste Dominioni is representing both Williams
and Head, and a spokesman from his office confirmed:
"Yes, Mr. Hill had the same modifications made to his
car as Ayrton Senna. And I think he believes the job was well
done. It was well done."
Around 40 witnesses are expected to give evidence before the
judge Antonio Costanzo, including Nelson Piquet, Gerhard Berger
and Riccardo Patrese.

Can Williams be sure?
1997 February 24
Williams have stated that Ayrton Senna's steering was working
until impact with the wall at the Tamburello curve. As a Physicist
and Master of Science, in Instrumentation and Dynamic Signal
Analysis, I believe that the Williams team cannot be sure whether
the steering system was working before impact or not, based only
on telemetry data.
Firstly, the steering angle is measured by a potentiometer
placed on top of the steering column, just behind the dashboard,
close to the steering wheel and above the break point. Any steering
wheel movement would be registered by the sensor but the steering
rods would not be responding properly due to failure of the steering
Secondly, a pressure sensor mounted on the hydraulic steering
system would inform that the oil pressure was O.K. but this does
NOT mean the whole steering system was operational. This sensor
only indicates problems in case of oil leakage and is used only
as a safety indicator against steering power loss.
Therefore I feel that the Williams affirmative lacks 'cause-effect'

Debris theory a ploy?
1997 February 24
From Joao Alcino Martins (Brazil)
Press reports and reaction to the Sunday Times' theory:
On February 18 Maurizio Passarini, the prosecutor on the Senna
case, declared that the alleged new evidence reported by the
Sunday Times is irrelevant to the line of charge. "The picture
does not change our conclusions."
The members of the technical team formed by Passarini to investigate
the tragedy are:
Mauro Forghieri - ex Technical Director for Ferrari
Enrico Lorenzini - Professor of Engineering at Bologna University
Tommaso Carletti - ex Ferrari race engineer
Alberto Bucchi - Professor at Bologna University and expert
in road construction systems
Francesco Bomparole - representative of state road contractors
Roberto Nosetto - ex president of the Imola circuit
Antonio del Monte - Professor of Science and Sports; ex-Ferrari
Emmanuelle Pirro - former F1 driver.
The Sunday Times (Feb 16) published a picture showing a small
piece of bodywork, likely to have come from JJ Lehto's Benetton,
lying on the asphalt. The newspaper's theory said that it is
possible that Senna would have tried to deviate from the piece,
lost control of the car because of cold tyres, and crashed.
Also the newspaper alleged that Senna could have kept his
respiration suspended in order to heighten his concentration
for the race restart and passed out.
The Brazilian press consider the Sunday Times theory could
be a ploy to deviate the attention away from the Williams team
and to lessen the charges laid against them. Some journalists
consider the theory ridiculous and nonsense
as there is NO technical evidence to support the statements.
Feb 19: Maurizio Passarini is said to have asked for large
screen TV's and will show second-by-second, the last minute of
Ayrton Senna's driving. The video footage will be coupled to
the Williams telemetry indications recovered from the Williams
"Each split second we will know what Senna was doing,
hitting gas, braking, turning wheels or changing gears"
The dates for the trial hearings are Feb 20, Feb 28 and March
Sagis, the company who were responsible for the Imola circuit,
published a statement declaring that the photo published in the
Sunday Times has been part of the investigation records since
Passarini confirmed this, and the fact the picture did not
add any significance to the proceedings.
Some newspapers consider the Senna case will be transformed
into a battle between England and Italy as 5 of those indicted
are from two nationalities.
The penalty under Italian law for manslaughter varies from
6 months to 5 years, but there are early records indicating the
penalty could be a fine, as in other race incidents.

What happened to the steering?
1997 February 24
From Joao Alcino Martins (Brazil)
Brazil's largest television company commented on the Sunday
Times' theory of Senna's death:
Regarding Senna's alleged breathing habit: Ayrton Senna was
the fittest driver in F1. The technique he used was NOT to keep
his breath suspended, on the contrary! Would Senna suspend his
breath for as long as 1min 30 sec?!
Williams telemetry and also rubber strips laid down on the
tarmac proved that Senna braked hard and changed
gear at least twice before impact. So he WAS
Even if the published picture was relevant: Would Senna have
even seen such a small piece of debris, and would he have been
able to begin any manoeuvre, considering he was close to 200mph?
It is alleged that at the time of the crash that many people
heard Patrick Head, in front of the TV monitor, when Senna started
to go straight, shouting "Steering power!"
And at the time of the impact "What happened to the steering?"
They said that as the witnesses worked for Williams, no-one
wanted to declare or confirm this fact publicly.

Williams. Windsor was a passenger when Frank Williams had the

Judge rejects defence challenges
1997 February 28
Antonio Costanzo, judge of the Ayrton Senna manslaughter trial,
rejected the challenges from two of the defence lawyers today.
At the trial opening on February 20, lawyers for Adrian Newey
and Roland Bruynseraede had argued that their clients had not
been warned, when interviewed by chief public prosecutor Maurizio
Passarini, they were under investigation. Both lawyers had demanded
that the technical evidence, which is key to the prosecution
case, be ruled inadmissible against their clients.
But Antonio Costanzo ruled that the proceedings against all
six accused should continue, and rejected the submissions as
A separate challenge on territorial jurisdiction from Newey's
counsel, stating the trial should be moved to Bologna, where
Senna was declared dead in hospital, was also discarded by the

The S Files
Don't blame Senna
1997 March 5
Faulty engineering by the Williams team and a defect in the
track were responsible for the death of Ayrton Senna, Public
Prosecutor Maurizio Passarini told the court today.
Passarini was opening the case for the prosecution in the
trial of the six men accused of manslaughter in connection with
Senna's death including Frank Williams, Patrick Head and Adrian
Newey. None of the accused were present, all were represented
by their lawyers.
Passarini pointed out two causes for the accident:
The first was a "modification to the steering column
which had been poorly executed causing it to break."
The second being that the car left the track because the asphalt
surface was not on the same level as the trackside. "There
was an angle with the side of the track," he said.
Williams' defence lawyer Oreste Dominioni immediately rejected
the accusation that the car was at fault, claiming that the state
of the track was to blame and that investigators had failed to
carry out proper tests on its surface.
"They should have determined whether the characteristics
of the course were such as to make the car lose stability and
leave the track," he said and called for a new technical
investigation of the circuit.
The move against the track was promptly countered by a group
of lawyers, representing Poggi, Bendinelli and Bruynseraede,
who said that ample checks and inspections had been carried out
on the Imola circuit.
Passarini said his case was that the steering column of Senna's
Williams car had been badly designed and was not strong enough
to withstand metal fatigue. Also that a welding job done when
the column was modified before the race had been poorly executed.
"The steering column had been cut and a new element -
which was not of the same quality of metal or of the same diameter,
being 18mm instead of 22mm - was welded in. And it was where
the new element had been welded in that the column broke."
"When Senna had a steering wheel dangling in his hands,
he was doing 192mph. He braked and hit the wall at 130 - 136
"If the track had been completely flat, he would have
been more able to brake and his speed could have been reduced
to 105 mph. Senna paid the price of these circumstances",
Dominioni denied that modifications to the steering column
had been done 'fast and furiously' before the Imola race, and
also pointed out that the steering column was identical to that
of the one used by Damon Hill in the other Williams car that
season. (See current NewSfile - Damon Hill's car also a death
The Williams' lawyer stated he would be able to demonstrate
that the column had broken after the crash and not before.
Roberto Landi, for Sagis, denied there had been anything wrong
with the track to cause the accident. He declared: "All
the world's circuits are like Imola."
Adrian Newey's lawyer demanded a new forensic examination
of the steering column on the grounds that Newey had not been
able to appoint his own expert to attend the original tests,
as he had not been warned he was under investigation and might
Passarini, who spoke for 90 minutes, also said he wanted to
counter suggestions that he was waging a vendetta against motor
racing by pointing out that no prosecution had resulted from
the fatal accident, the day before Senna was killed, involving
That accident occurred because of damage to the car sustained
when it left the track earlier rather than because of design
or construction errors, he stated. Only in the case of Senna
have the investigations demonstrated a case of manslaughter.
Passarini then asked judge Antonio Costanzo to admit various
pieces of evidence, including a recording of film taken by a
camera on Senna's car, analysis by consultants and a digital
reconstruction of the accident using television pictures taken
from several angles.
He said he also wanted to use as evidence records regarding
crashes on the same bend by other drivers in previous years:
Nelson Piquet in 1987, Gerhard Berger in 1989, Michele Alboreto
in 1991 and Riccardo Patrese in 1992.
In addition Passarini wanted to refer to television pictures
showing various cars grounding on the corner and sending up showers
Finally he wanted to admit film showing an object thrown into
the air by the wheels of either Senna's car or Schumacher's close
Soon after the crash, using 'slow motion' replay, French
TV studied the view from Schumacher's on-board camera. According
to the French channel, a small piece could be seen dangling from
underneath Senna's Williams, which flew off the track immediately
after this.- Ed.
Referring to a recent article in the British Sunday Times
newspaper which suggested that a piece of debris was the cause
of Senna's crash, (See this NewSfile - Co-author is friend
of Frank Williams - 1997/02/24 also NewSfile #3 - Blue speck
in the death of Ayrton Senna - 1997/02/17), Passarini said:
"But I wish to clarify that I do not attribute any causal
significance to the small object on the track. An enquiry by
experts revealed that NO blame can be attached to Senna: he HAD
NOT taken any drugs, he DID NOT make a driving error and he DID
NOT pass out - contrary to reports in the British press."
"There was no illness because Senna desperately tried
to stop the car until the end."
Dominioni said he would be calling as witnesses both Damon
Hill and Massimo Angelini, who was driving the safety car which
led the drivers around the circuit before the race restarted.
There have been reports that Senna asked Angelini to speed up
because his tyres were losing temperature.
Antonio Costanzo, the magistrate dealing with the trial
closed today's session by accepting all the documents and
expert reports presented earlier by both the defence and the

Damon Hill, Senna's team mate at the time of the accident,
has been called to appear on April 28 and will be questioned
by both the defence and the prosecution. Ecclestone is due before
the court on April 22.
The next trial session will be held on March 11, with the
appearance of Italian technical experts and the first witnesses.
The S Files
First witness called in Senna trial
1997 March 11
The trial resumed today at Imola with the opposing strategies
of the prosecution and the defence coming into sharp focus. The
defence claims that poor track conditions caused the accident.
The prosecution states that Senna's steering column broke due
to faulty welding executed two weeks before the race, when the
car was modified to make the driver more comfortable.
The focus of early testimony today were the design changes
made on Senna's car, with Chief Prosecutor Maurizio Passarini
pointing out a metal plate that was allegedly welded onto the
rear suspension after the suspension was damaged during winter
testing at Le Castellet in France.
Passarini said: "I mention that not to say that the rear
suspension was the cause of the accident but to note that, despite
the fact that these are very sophisticated vehicles, when a problem
occurs it is patched up with a metal plate."
Passarini was referring to the prosecution theory regarding
the steering column modification.
Among the witnesses called was Mario Casoni, driver of one
of the emergency vehicles that attended the scene of crash. Casoni
said "I noticed the abnormal state of Senna's steering column,
which had been uprooted and was dangling from the cockpit."
Williams lawyer Oreste Dominioni then pounced on the fact
that in 1994 Casoni had said the column was lying on the ground.
Casoni replied that he had made a mistake in his statement given
to a police officer at the time.
Oreste Dominioni for the defence, pointed to problems with
the track surface and said it had not been fully investigated.
Lawyer Roberto Landi, representing Federico Bendinelli, director
of Sagis, intervened and said that an inquiry had ruled out problems
with the track. An amateur video taken at Imola on March 9 1994
during private testing, shows Senna with track director Giorgio
Poggi and others, discussing the track conditions on the Tamburello
Another witness, police inspector Stefano Stefanini, head
of Bologna's traffic accident unit, said Senna was complaining
about depressions in the asphalt, which were reportedly taken
care of the following day by track workers.
But under questioning by Dominioni, Stefanini did admit that
track management had not been consulted regarding this incident,
only the director of the crew that fixed the problem. Seen as
preventing a defence bid to blame the condition of Senna's tyres,
Passarini called on Stefanini to give lap times.
Senna, with a fully loaded car, clocked 1 min 24.887sec on
the sixth lap of the restarted race. "That was a very good
time," said Stefanini,"only two drivers bettered it
- Damon Hill and Michael Schumacher - and that was at the end
of the race."
Falling tyre pressures/adherence has been a topic of speculation
by the media since the accident.
Traffic police commissioner Marcello Gentili was asked about
the cars trajectory and signs of braking prior to impact, to
ascertain whether problems with the asphalt could have caused
the crash. Gentili said there was a 21cm angle between the track
and the trackside and there were intermittent signs of braking.
Two doctors who pulled Senna from the wreckage testified that
they did not encounter any obstacles in pulling his body out
of the car. This led them to suppose that the steering column
was already broken.
The S Files
The bump effect was normal
1997 March 12
The second trial session of the week continued with chief
prosecutor Maurizio Passarini calling Pierluigi Martini to testify
as a former Formula One driver knowledgeable of both the Imola
circuit and the Tamburello curve.
Martini said: A driver like Ayrton Senna didn't go off the
track at that point unless there was a problem. A lot of things
can happen during a race, but in this particular case I don't
know what the problem could have been. Drivers took the curve
at 300km/h and there was a small dip in the middle of the track
which disturbed the cars. The bump effect was perfectly normal
and is common to every racing circuit in the world.
I was at Imola with Senna and others two weeks before the
race when we noticed a small bump in the Tamburello bend.
The circuit officials were very efficient, and had the asphalt
smoothed out, which was the only thing they could do. The cars
still touched the ground and were disturbed so you just had to
hold your line.
The repairs had only slightly improved the situation. Senna
had complained to me three weeks before Imola at Aida (Japan),
that his car was nervous and the cockpit narrow. But Tamburello
could have only created problems for a car that had problems.
The people at Imola did everything they could to give us drivers
what we asked for.
Martini felt he could not say that the Tamburello bump had
caused Senna to veer off the track. There was only one line into
Tamburello and the bump could not be avoided without leaving
the track. He added that Senna's fast lap time indicated that
his tyres were fully warmed up.
Eight course officials who were present at the Imola race
were then questioned by Passarini as to whether or not they had
been aware of anything lying in the path of Senna's car, and
whether they believed his Williams-Renault had left the Tamburello
curve in a straight line.
All felt that Senna's car went off in a straight line towards
the wall and all said there had been nothing in his way.
The trial continues on March 17 with further witnesses including
an electronics expert from Williams' engine supplier Renault.
FIA race delegate, Charlie Whiting is expected to testify
the following day.

Williams engineers called as witnesses
1997 March 16
Williams engineers Alan Young and Gavin Fisher are to appear
as witnesses in the Senna trial according to reports. Fisher
and Young will answer allegations that Senna's steering column
was altered before the start of the season and again after the
Japanese Grand Prix.
Luigi Stortoni, representing Adrian Newey said:
"The modification of Senna's steering rod was in the
hands of Fisher and Young. That is why we have called them as
"It wasn't a rush job, it was planned and we don't think
welding was the cause of the accident."
"Let's face it, Senna was a driver. He had complete faith
in the experts. What could he say about modified steering rods?"

Black boxes were scratched but intact
1997 March 17
The trial resumed with conflicting claims regarding the condition
of the two black box data recorders carried in Senna's car. The
first belonging to Williams, was designed to record data from
the chassis and gearbox, the second belonging to Renault stored
information on the V10 engine.
Fabrizio Nosco said he had removed both black box data
recorders from Senna's Williams after the crash, having obtained
permission from Charlie Whiting the FIA representative.

Duffort said the data from the Renault box was transferred
onto a computer disc on the day of the crash and a copy was handed
to the Italian authorities on May 18, along with the data recorder.
By that time, however, the recorder's information was no longer
available. Duffort said that tests on the recorder, which erased
its data, were carried out in Paris on an engine test bench several
Senna had mechanical failure
The ex-Formula One driver, Michele Alboreto, testified in
court today that he believed Senna's fatal crash was caused by
a mechanical failure in the car and not a fault of of the race
The driver gave his verdict after viewing a video of the crash,
replayed in the courtroom, in particular pictures coming from
a camera onboard Michael Schumacher's car, which was close behind
Film was also shown of previous crashes at Tamburello - involving
Gerhard Berger, Nelson Piquet, Riccardo Patrese and Alboreto
He told reporters afterwards: "Senna's shift to the right
makes me think it was a mechanical failure. The situation at
Imola was not exceptional, we've raced in much worse conditions
that those. I hope this trial helps us understand what really
happened to Senna, because it still isn't clear. Mechanical failures
are frequent, given the nature of the races and people always
aim for the limit. But no engineer can ignore safety."
He went on to describe the bumps on the track surface just
before the curve, which have been the target of Williams' lawyer
Oreste Dominioni, as minor and said they could not have forced
Senna's car off the circuit.
The trial continues tomorrow with testimonies from more witnesses,
including FIA delegate Charlie Whiting. It is still not known
whether Patrick Head, technical director at Williams would attend.
