GIGN commando Philippe Bardelli was leading a column up the front right stairs, as that team was tasked with throwing stun grenades in the cockpit, when a 7.62 × 39 mm bullet from an AK-47 hit his drawn pistol and detonated the cartridges; Bardelli later remarked that his pistol which was hit saved his life since such AK-47 rounds were able to penetrate the GIGN's helmet visors. The remaining hijacker kept the GIGN at bay for 20 minutes, but he eventually ran out of ammunition and died from a gunshot wound. Meanwhile, the GIGN operatives were not sure which men were the hijackers and how many were still alive, so they considered all male passengers as potentially being hijackers. The flight engineer, Alain Bossuat, radioed the tower stating that the hijackers were dead and that there were no more left. This signaled to GIGN forces that a final clearing of the A300 could begin. Delhemme said that when the forces entered the aircraft, they ordered him to put his hands on his head. Delhemme said that, after the hijacking ordeal had run its course, he refused to leave with his hands on his head and be "punished like a child". Burgniard said that when she saw Bossuat handcuffed, the cabin crew told the forces to let him go as the individual was the flight engineer. At 5:35 pm, Favier radioed to the tower that the incident was over; the incident unfolded in 54 hours.
