have been many attempted explanations for the cause of his death, but
no consensus has been reached. His death was a turning point in the
safety of Formula One, as many safety measures have since been
implemented. The Grand Prix Drivers' Association was reformed later in
1994, and the association has contributed to these changes.BACKGROUND
May 1, 1994, Senna took part in his third race for the Williams team,
the San Marino Grand Prix at the Imola circuit. Although he would not
finish it, Senna started his final Formula One race from pole position.
weekend, he was particularly upset by two events. On Friday, during the
afternoon qualifying session, Senna's protégé, F1 newcomer Rubens
Barrichello, was involved in a serious accident that prevented him from
competing in the race. On Saturday, the death of Austrian driver Roland
Ratzenberger in qualifying, deeply upset Senna, reinforcing his safety
concerns and made him consider retiring from the sport. Ironically, he
spent his final morning meeting fellow drivers, determined after
Ratzenberger's accident to take on a new responsibility to re-create the
Grand Prix Drivers' Association, a Drivers' Safety group to increase
safety in Formula One. As the most senior driver, he was offered to take
the role of leader in this effort. The Accident
Sunday, Pedro Lamy and JJ Lehto were involved in a starting-line
accident. Track officials deployed the safety car to slow down the field
and allow the debris from the starting accident to be removed. The cars
proceeded under the safety car for 5 laps.
On lap 7, from the
onboard camera of Michael Schumacher's Benetton, Senna's car was seen to
break traction twice at the rear, go off the track at Tamburello corner
and strike an unprotected concrete barrier. Telemetry shows he left the
track at 310 km/h (190 mph) and was able to slow the car down to 218
km/h (135 mph) in slightly under 2 seconds before hitting the wall.

Senna's car came to a halt, he remained motionless in the cockpit.
Although the car had suffered a high speed impact with the wall, the
accident did not have the typical hallmark of an especially devastating
racing crash. The car simply seemed to understeer strongly off the
track, hit the wall at a shallow angle, tearing off the right front
wheel and nosecone, lift slightly with the nose as it straightened, and
spin mildly to a halt.
Although the crash seemed benign, it was
immediately evident that Senna had suffered some form of injury because
of the manner in which his helmet was seen to be motionless and leaning
slightly to the side. In the seconds that followed his head was seen to
move to one side slightly causing false hopes to be raised. A
considerable amount of time passed before medical units came to his aid,
with fire marshals having arrived at the car and unable to touch Senna
before qualified medical personnel arrived. Television coverage from an
overhead helicopter was seen around the world, as rescue workers gave
medical attention. Close inspection of the area in which the medical
staff treated Senna revealed a considerable amount of blood on the
ground. The race was stopped 1 min. 9 seconds after Senna's crash.
10 minutes after Senna's crash, a miscommunication in the pits caused a
Larrousse car piloted by Érik Comas to leave the pit lane and attempt
to rejoin the now red flagged Grand Prix. That incident with Comas was
spotted by Eurosport Commentator John Watson as the "most ridiculous
incident I ever saw at any time in my life". Frantic waving by the
marshals at Senna's crash site prevented the Larrousse from risking a
collision with the medical helicopter that had landed on the track.
Sidney Watkins, a world-renowned neurosurgeon and Formula One Safety
Delegate and Medical Delegate, head of the Formula One on-track medical
team, who performed an on-site tracheotomy on Ayrton Senna, reported:
He looked serene. I raised his eyelids and it was clear from his pupils
that he had a massive brain injury. We lifted him from the cockpit and
laid him on the ground. As we did, he sighed and, although I am totally
agnostic, I felt his soul depart at that moment.Accident analysis
2004, a television documentary by National Geographic called Seismic
Seconds: The Death of Ayrton Senna was screened worldwide. The program
considered the available data from Senna's car to reconstruct the
sequence of events that led to the fatal crash. The program concluded
that an unusually long safety car period had reduced the pressures in
Senna's tyres, thereby lowering the car. As the car entered the
Tamburello bend, the skid-plate on the bottom of the car connected with
the ground, rendering the car's steering and lateral grip useless. Senna
reacted with lightning-fast reflexes, but as the car passed over the
bump and regained grip the steering wheel now was in a right-lock
corrective position, the car effectively drove off the circuit.
many within the F1 world including some drivers of that era who had
raced at Imola, the conclusions drawn from low tyre pressure as a cause
of the accident seem implausible. Telemetry recorded that Senna took the
bend at 306 km/h (190 mph) on lap 6 with cold tyres. The information
released in the trial stated that Senna started the race with 86 litres
of fuel and had planned a two stop race strategy, one fewer than
Schumacher, who started the race lighter on a 3 stop strategy. The
theory that low tyre pressure caused the crash was defeated in court
when Stefano Stefanini, head of Bologna's traffic accident unit,
testified that Senna, with a heavier car than Michael Schumacher and
Damon Hill, recorded a time of 1.24.887 on the sixth lap, Senna's only
lap at race speed and the 3rd fastest lap of the race. Michele Alboreto
and other drivers of the era claimed that given Senna's lap time, his
tyres would have been at race temperature by the 7th lap and could not
have been a factor in the crash.
Some drivers indicated that
Senna's crash was due to driver error. Michael Schumacher, who had
followed closely behind the Brazilian before the crash, gave the
following account at the subsequent winners' press conference:
I saw that his car was already touching quite a lot at the back on the
lap before, the car was very nervous in this corner, and he nearly lost
it. On the next lap he did lose it. The car touched with the rear skids,
went a bit sideways, and he just lost it.
Damon Hill, Senna's teammate at the time of his death, had this to say in an interview given on the subject 10 years later:
I am convinced that he made a mistake, but many people will never
believe that he could. Why not? He made many mistakes in his career. I
have listened to and read endless theories about why, or how, he could
have crashed on such a 'simple' corner like Tamburello. No-one other
than Ayrton Senna and me know what it was like to drive that car,
through that corner, in that race, on that day, on cold tyres. He was
identified with pushing to the limit and beyond. It was not the fault of
anyone else that he kept his foot flat when he could have lifted.
ban on active suspension affected Williams more than any other team as
it was the key development that had helped make the Williams car the
class of the field during 1992 and 1993 seasons. After active suspension
was banned in 1994 the Williams drivers complained of severe handling
problems and a twitchy rear-end. The FW16's new rear end was introduced
at Imola. It was ironic that at the beginning of 1994 Senna himself told
the press that he would be surprised if there would be no large
accidents that year. He referred to the fact that after the wide "white
label" 18 inch wide Goodyear slicks were replaced for 1993 by the
narrower "yellow label" 15 inch wide slick, now the technology at the
very core of the cars, the science around which they had been based for
the last few years (active suspension, traction control and ABS) was
also banned for 1994. He surmised that the cars would have trouble
staying on the road, which is exactly what was observed at the beginning
of 1994. J. J. Lehto damaged his vertebrae at Silverstone in January
(as did Jean Alesi, causing him to miss Imola) prior to Ratzenberger's
and Senna's fatal accidents at Imola. During qualifying for the next
race at Monaco, Karl Wendlinger suffered an accident which left him in
an induced coma; Ratzenberger's replacement, Andrea Montermini, broke
his feet in the Simtek in Barcelona and Eddie Irvine was banned for
three races after causing an accident during the season-opening
Brazilian Grand Prix. None of these accidents were deemed to be caused
by driver error (except Irvine's), although there is no evidence to
suggest that the accidents were caused by the ban on driver aids.
are other factors – Senna did not like the position of the steering
column relative to his seating position and had repeatedly asked for it
to be changed. At Imola Senna found himself in a car with his team's
engineers struggling to cope and adapt to the ban of active suspension.
Patrick Head and Adrian Newey agreed to Senna's request to lengthen the
FW16's steering column, but there was no time to manufacture a longer
steering shaft. The existing shaft was instead cut, extended by
inserting a smaller diameter piece of tubing and welded together with
reinforcing plates. Many surmise, based on comparing hours of onboard
video footage from Brazil and Imola that the movement of the steering
wheel during the race at Imola was completely abnormal. Senna on his
final lap is seen turning the wheel left to full lock with no movement
of the front wheels. Others have raised suspicion at what can clearly be
seen on the onboard footage as Senna looking down at his steering wheel
seconds before entering Tamburello.
Senna's distinctive helmet
irony of the on board video available from Senna's car is that the
final seconds of footage are missing. The approximately 1.5 seconds of
remaining video which would have provided a definite answer as to the
cause of Senna's death were lost in an act of astounding coincidence
when the TV race director decided to switch camera signals at the very
instant the Williams started to leave the track.
unsurprisingly, numerous rumours abound that the remaining 1.5 seconds
are not lost and reportedly show Senna's steering wheel clearly coming
off in his hands as his car is leaving the track. In addition to this,
the video shown in the Court Room on May 14, 1997 stopped 0.9 seconds
before the impact , causing numerous questions. Although allegations
exist that this video has been seen by a number of people at the top
level of motorsport, there is no evidence to support its existence.
Williams team was entangled for many years in a court case with the
Italian prosecutors over manslaughter charges, but they were found not
guilty and no action was taken against Williams. In 2004, the case was
re-opened, but closed again in 2005 when there was no new evidence.
the trials , Fabrizio Nosco, a Regional technical commissioner,
testified that both of the vehicle's black boxes were intact, except for
minor scratches. He said "I have seen thousands of these devices and
removed them for checks. The two boxes were intact, even though they had
some scratches. The Williams device looked to have survived the
crash.". In a move that disrespected FIA regulations at the time,
Charles Whiting, a FIA official, handed the black boxes to Williams
before the regulating body's own investigation into the accident.
Williams claimed the black boxes were unreadable, and the boxes returned
for the court proceedings were indeed unreadable, a full month after
the accident. The black boxes would have put to rest the cause of the
At the conclusion of the Italian trial, Senna's FW16,
chassis number 02, was returned to the Williams team. The team reported
that the car was in an advanced state of deterioration and was
subsequently destroyed. The car's engine was returned to Renault, and
its fate is unknown.
His death was considered by many of his
Brazilian fans to be a national tragedy, and the Brazilian government
declared three days of national mourning. More than 1 million persons
followed Senna's burial in São Paulo. Senna is buried at the Cemitério
do Morumbi in his hometown of São Paulo.Legacy
the deaths of Senna and Ratzenberger, many safety improvements were
made. Although other drivers had died before him, Senna had arguably the
highest profile. Improved crash barriers, redesigned tracks and tyre
barriers, higher crash safety standards, and higher sills on the driver
cockpit are among the measures that were subsequently introduced. Since
Senna's death, no drivers have died behind the wheel of a Formula One
car, despite large accidents still occurring.
After the crash,
race officials found a furled Austrian flag in the cockpit of Senna's
car. It seems that Senna had intended to dedicate his 42nd victory to
the memory of Roland Ratzenberger.
GRAND PRIX RESULTS: SAN MARINO GP, 1994
San Marino GP
May 1, 1994
58 Laps, 5.04 km
The unpleasant atmosphere in Formula 1 in the
Spring of 1994 was bubbling to the surface before the San Marino GP
with pressure building for a solution to the problems of electronic
driver aids which the FIA was obviously having trouble controlling.
Although these aids were banned there was suspicion that Benetton was still using them. No-one anticipated the disastrous weekend that was ahead.
The field was as it had been in Aida, except that JJ Lehto was back in action for Benetton and Jordan had replaced Aguri Suzuki with Andrea de Cesaris (Eddie Irvine was still serving his three-race ban for causing a huge accident in Brazil).
The disasters began on Friday when Rubens Barrichello crashed his Jordan
heavily at the fast corner before the pits. The car took off and hit
the top of the barrier. It was then launched back onto the track where
it came to rest upside down. Barrichello was unconscious and he had
swallowed his tongue but quick intervention from the medical teams saved
him although he was out for the rest of the weekend. Ayrton Senna, driving his Williams to the limit, set the fastest time of the day. The next day was even worse when Roland Ratzenberger crashed at high speed into the wall at Villeneuve Corner (named after the late Gilles Villeneuve).
A front wing flap had fallen off the car and launched it off the ground
at 200mph. It hit the wall at around 180mph and came to a halt with
Ratzenberger slumped in the wreck. He was beyond help but was flown to
hospital in Bologna, where he was officially certified dead a few
minutes after arrival.
The session was eventually restarted but only a handful of drivers improved their times. Senna was on pole with Michael Schumacher (Benetton) second and Gerhard Berger (Ferrari) third. Damon Hill was fourth fastest in the second Williams with JJ Lehto (Benetton) fifth and Ferrari's Nicola Larini (standing in for the injured Jean Alesi) sixth. The top 10 was completed by Heinz-Harald Frentzen (Sauber), Mika Hakkinen (McLaren), Ukyo Katayama (Tyrrell) and Karl Wendlinger (Sauber).
At the start of the race Lehto stalled. Most of the cars missed the stationary Benetton but then Pedro Lamy arrived at the scene unsighted in his Lotus
and he ran into the left rear of the car. The Lotus 's right hand
wheels and other wreckage was thrown high into the air, over the debris
fence and into the grandstand. Four people were hit. A Safety Car was
sent out and for four laps the field stayed behind the car as the
wreckage was cleaned up and the injured spectators looked after. Then
the race was restarted with Senna leading with Schumacher
right on his tail. At the start of the sixth lap Senna's car went
straight off at Tamburello Corner. The Brazilian tried to turn the car
in the final moments before hitting the wall but there was no escape.
The car hit the wall! In the impact the front suspension of the Williams
came back and hit Senna on the head. The car bounced back towards the
track, throwing wreckage into the air, and slid to a halt beside the
circuit. The doctors fought to save Senna's life and he was rushed by
helicopter to Bologna. But from early on it was clear that there was no
hope. Ayrton Senna died that evening.
The extent of Senna's injuries were not clear to many in the paddock and no-one complained that the race was restarted from the grid. Berger took the lead on the road but Schumacher
was still ahead on aggregate. Schumacher went ahead on lap six of the
new race and soon afterwards Berger retired with a rear wheel problem.
When Schumacher pitted Larini
led for a while but then Schumacher reasserted himself. The race went
on with Schumacher dominant and during the second round of pit stops
there was another accident in the pitlane when Michele Alboreto's Minardi lost a wheel and slewed into the Ferrari mechanics. A Lotus mechanic was also hit by debris.
Finally the race ended with Schumacher winning from Larini (his achievement completely overshadowed by the dreadful events). Third place went to Hakkinen with Wendlinger fourth, Katayama fifth and Hill sixth.
But the racing was irrelevant that day.
