Air traffic controller Gilles Logelin noticed the flames before the Concorde was airborne and informed the flight crew. However, the aircraft had passed V1 speed, at which point takeoff is considered unsafe to abort. The plane did not gain enough airspeed with the three remaining engines as damage to the landing gear bay door prevented the retraction of the undercarriage. The aircraft was unable to climb or accelerate, and its speed decayed during the course of its brief flight. The fire caused damage to the inner elevon of the left wing and it began to disintegrate, melted by the extremely high temperatures. Engine number 1 surged again, but did not fully recover, and the right wing lifted from the asymmetrical thrust, banking the aircraft to over 100 degrees. The crew reduced the power on engines three and four in an attempt to level the aircraft, but they lost control due to deceleration and the aircraft stalled, crashing into the Hôtelissimo Les Relais Bleus Hotel. A video of the burning plane on takeoff and the aftermath of the crash was captured by a passing driver.
