Death of Ayrton Senna
From Wikipedia, the free encyclopedia
The death of Formula One triple world champion Ayrton Senna resulted from a crash that occurred while he was leading the 1994 San Marino Grand Prix at Imola.

[edit] Background
On 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.
That weekend, he was particularly upset by two events. On the 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 practice, 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.
[edit] Accident
On Sunday, Pedro Lamy and J. J. 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 6 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.
After 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 sort of injury because of the manner in which his helmet was seen to be mostly motionless and leaning very 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 long time seemed to go by 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.
During this time a miscommunication in the pits caused a Larrousse F1 car piloted by Érik Comas to leave the pit lane and attempt to rejoin the now red flagged Grand Prix. Frantic waving by the marshalls at Senna's crash site prevented the Larousse from risking a collision with the medical helicopter that had landed on the track. Professor 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.[1] | ” |
[edit] Autopsy
Senna was 34 years old at the time of his death. What had likely happened was that the right front wheel had shot up after impact like a catapult and entered the cockpit area where Senna was sitting. It struck the right frontal area of his helmet, and the violence of the wheel’s impact pushed his head back against the headrest, causing fatal skull fractures. A piece of upright attached to the wheel had partially penetrated his helmet and caused a trauma to his head. In addition, it appeared that a jagged piece of the upright assembly had penetrated the helmet visor just above his right eye. Any one of the three injuries would probably have killed him. [2]
The FIA and Italian authorities still maintain that Senna was not killed instantly, but rather died in hospital, to where he had been rushed by helicopter after an emergency tracheotomy and IV administration were performed on track. There is an ongoing debate as to why Senna was not declared dead at the track. Under Italian law when a person dies at a sporting event, that death must be investigated, causing the sporting event to be cancelled. The Director of the Oporto (Portugal) Legal Medicine Institute, Professor José Eduardo Pinto da Costa, has stated the following:
| “ | From the ethical viewpoint, the procedure used for Ayrton's body was wrong. It involved dysthanasia, which means that a person has been kept alive improperly after biological death has taken place due to brain injuries so serious that the patient would never have been able to remain alive without mechanical means of support. There would have been no prospect of normal life and relationships. Whether or not Ayrton was removed from the car while his heart was beating or whether his supply of blood had halted or was still flowing, is irrelevant to the determination of when he died.
The autopsy showed that the crash caused multiple fractures at the base of the cranium, crushing the forehead and rupturing the temporal artery with haemorrhage in the respiratory passages. It is possible to resuscitate a dead person immediately after the heart stops through cardio-respiratory processes. The procedure is known as putting the patient on the machine. From the medical-legal viewpoint, in Ayrton's case, there is a subtle point: resuscitation measures were implemented. From the ethical point of view this might well be condemned because the measures were not intended to be of strictly medical benefit to the patient but rather because they suited the commercial interest of the organisation. Resuscitation did in fact take place, with the tracheotomy performed, while the activity of the heart was restored with the assistance of cardio-respiratory devices. The attitude in question was certainly controversial. Any physician would know there was no possibility whatsoever of successfully restoring life in the condition in which Senna had been found. [3] |
” |
Professor Jose Pratas Vital, Director of the Egas Moniz hospital in Lisbon, a neurosurgeon and Head of the Medical Staff at the Portuguese GP, offers a different opinion:
| “ | The people who conducted the autopsy stated that, on the evidence of his injuries, Senna was dead. They could not say that. He had injuries which lead to his death, but at that point the heart may still have been functioning. Medical personnel attending an injured person, and who perceive that the heart is still beating, have only two courses of action: One is to ensure that the patient's respiratory passages remain free, which means that he can breathe. They had to carry out an emergency tracheotomy. With oxygen, and the heart beating, there is another concern, which is loss of blood. These are the steps to be followed in any case involving serious injury, whether on the street or on a racetrack. The rescue team can think of nothing else at that moment except to assist the patient, particularly by immobilising the cervical area. Then the injured person must be taken immediately to the intensive care unit of the nearest hospital. [4] | ” |
Rogério Morais Martins states that:
| “ | According to the first clinical bulletin read by Dr. Maria Teresa Fiandri at 4.30 p.m. Ayrton Senna had brain damage with haemorrhaged shock and deep coma. However, the medical staff did not note any chest or abdomen wound. The haemorrhage was due to the rupture of the temporal artery. The neurosurgeon who examined Ayrton Senna at the hospital mentioned that the circumstances did not call for surgery because the wound was generalised in the cranium. At 6.05 p.m. Dr. Fiandri read another communiqué, her voice shaking, announcing that Senna was dead. At that stage he was still connected to the equipment that maintained his heartbeat.
The release by the Italian authorities of the results of Ayrton Senna's autopsy, revealing that the driver had died instantaneously during the race at Imola, ignited still more controversy. Now there were questions about the reactions of the race director and the medical authorities. Although spokespersons for the hospital had stated that Senna was still breathing on arrival in Bologna, the autopsy on Ratzenberger [who died the day before] indicated that death had been instantaneous. Under Italian law, a death within the confines of the circuit would have required the cancellation of the entire race meeting. That in turn, would have prevented the death of Ayrton Senna. The relevant Italian legislation stipulates that when a death takes place during a sporting event, it should be immediately halted and the area sealed off for examination. In the case of Ratzenberger, this would have meant the cancellation of both Saturday's qualifying session and the San Marino Grand Prix on Sunday. Medical experts are unable to state whether or not Ayrton Senna died instantaneously. Nevertheless, they were well aware that his chances of survival were slight. Had he remained alive, the brain damage would have left him severely handicapped. Accidents such as this are almost always fatal, with survivors suffering irreversible brain damage. This is due to the effects on the brain of sudden deceleration, which causes structural damage to the brain tissues. Estimates of the forces involved in Ayrton's accident suggest a rate of deceleration equivalent to a 30 metre vertical drop, landing head-first. Evidence offered at the autopsy revealed that the impact of this 208 km/h crash caused multiple injuries at the base of the cranium, resulting in respiratory insufficiency. There was crushing of the brain (which was forced against the wall of the cranium causing oedema and haemorrhage, increasing intra-cranial pressure and causing brain death), together with the rupture of the temporal artery, haemorrhage in the respiratory passages and the consequent heart failure. There are two opposing theories on the issue of whether the drivers were still alive when they were put in the helicopters that carried them to hospital. Assuming both Ratzenberger and Senna had died instantaneously, the race organisers might have delayed any announcement in order to avoid being forced to cancel the meeting, thus protecting their financial interests. Had the meeting been cancelled, Sagis - the organisation which administers the Imola circuit - stood to lose an estimated US$6.5 million.[5] |

The FIA dismisses that allegation as an unfounded conspiracy theory.[citation needed]
The FIA immediately investigated the Autodromo Enzo e Dino Ferrari in Imola, and the track's signature Tamburello turn, was changed into a left-right chicane.
In 2000, Senna was posthumously inducted into the International Motorsports Hall of Fame.

In 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 reflexes, but as the car regained grip and steering with the steering wheel in a right-lock corrective position, Senna effectively drove off the circuit.
To 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, Ayrton'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.[6] | ” |
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.[7] | ” |
The 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 1991, 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" 26 inch Goodyear slicks were banned for 1993 (replaced by the narrower "yellow label"), 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 and Jean Alesi broke his neck in pre-season testing, 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 comatose for months; Ratzenberger's replacement, Andrea Montermini, broke his feet in the Simtek in Barcelona, and Pedro Lamy broke both knee-caps in testing at Silverstone in May. None of these accidents were deemed to be caused by driver error, although there is no evidence to suggest that the accidents were caused by the ban on driver aids.
There 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.
The 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.
Perhaps 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 [2], 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.
The 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.
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.
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.
[edit] Legacy
Before his death, he created the Ayrton Senna Foundation, an organization with the aim of helping poor and needy young people in Brazil and around the world. As a result, Senna continues to impact the world today and has become a beacon of hope to millions of his countrymen and an example of professionalism and humanity to those who remember him.
In 2004 (when, ten years after his death, the Brazilian media revisited the entire life of Senna), a book called "Ayrton: The Hero Revealed" (original title: "Ayrton: O Herói Revelado" [8]) was published in Brazil. The book recalls several passages of Senna's career, and adds previously unknown information about his personal life.
In addition, to mark the 10th anniversary of Senna's passing, on April 21, 2004, over 10,000 people attended a charity match in a football stadium near Imola. The game was organized by several devoted Italian and Canadian fans of Ayrton, bringing together the 1994 FIFA World Cup winning team of Brazil who dedicated their 1994 FIFA World Cup win to Ayrton Senna to face the "Nazionale Piloti", an exhibition team comprised exclusively of top race car drivers (of which Senna was a part in 1985). Michael Schumacher, Jarno Trulli, Rubens Barrichello, Fernando Alonso and many others faced the likes of Dunga, Careca, Taffarel and many of the team that won the World Cup in the USA ten years earlier.
That same weekend, Bernie Ecclestone revealed that he still believed Ayrton Senna was and remained the best F1 driver he'd ever seen. Murray Walker said, "to say that his loss is tragic is a masterpiece of understatement."[9]
In 2005, Italian singer Cesare Cremonini released a song entitled, "Marmellata #25", and in the chorus he has part of a line that reads in Italian "Ahh! Da quando Senna non corre più... non è più domenica!", which translates to: "Oh! Since Senna doesn't race anymore...it's not Sunday anymore!"
Perhaps the unique duality of his character was most evident at the moment of his death. As track officials examined the wreckage of his racing car they found a furled Austrian flag. A victory flag that he was going to raise if he won the race, in honour of Austrian Roland Ratzenberger, who had died on that track the day before.[10]
Most of Formula One attended Senna's state funeral, but the president of FIA, Max Mosley, did not. He attended the funeral of Ratzenberger instead which took place on May 7, 1994 in Salzburg, Austria.[11] Mosley said in a press conference ten years later, "I went to his funeral because everyone went to Senna's. I thought it was important that somebody went to his."[12]
At Senna's funeral service an estimated one million people lined the streets to give him their final salute.
