Formula 1 faced its darkest month in May 1994 when three drivers suffered catastrophic accidents within weeks. Roland Ratzenberger and Ayrton Senna died at Imola's San Marino Grand Prix, while Karl Wendlinger sustained severe head injuries during Monaco practice after his Sauber slammed sideways into barriers.

The consecutive crashes exposed fundamental safety flaws in open-cockpit racing. With global scrutiny intensifying, the FIA launched urgent reforms that would reshape motorsport protections. While seatbelt improvements and circuit changes drew immediate attention, one lesser-known innovation emerged: experimental driver airbag systems.

Though never fully adopted in F1, the FIA's airbag research pioneered energy-absorbing materials now used in helmets and cockpit padding. The 1994 crisis ultimately birthed the Head and Neck Support (HANS) device and stricter crash-test standards, saving countless lives across racing categories.
