As someone who has followed Formula 1 since the early 90s, the 1994 San Marino Grand Prix has always stood out as a devastating turning point in the sport’s history. What follows is a detailed summary of the circumstances surrounding the deaths of Roland Ratzenberger and Ayrton Senna, based on technical analysis and official sources.
🟥 Roland Ratzenberger – April 30, 1994 (Qualifying)
Cause: Front wing failure at ~310 km/h after damage from a previous curb hit.
Impact: Crashed into the concrete wall at Villeneuve curve.
Deceleration: Estimated at over 500 G – enough to cause instant fatal trauma.
Injury: Severe skull fracture; autopsy suggested additional internal injuries due to the front wheel penetrating the chassis and possibly his body.
Notes: The survival cell was compromised. No chance of survival.
🟦 Ayrton Senna – May 1, 1994 (Race)
Incident: Senna’s car went straight at Tamburello corner due to suspected steering column failure.
Speed: Estimated at 218 km/h at impact.
Deceleration: 40–60 G (less than Kubica 2007 [75 G], Barrichello 1994 [95 G]).
Fatal Injury:
A suspension arm, still attached to the front right wheel, pierced his Bell M3 helmet and fractured the base of his skull.
Simultaneously, the wheel struck the right front side of his helmet, causing his head to jerk violently backward, possibly resulting in cervical spine trauma.
Speculation: Without the debris impact, he may have survived — given that similar or worse G-forces have been survived by other drivers.
