This is a bit of old news, an event that took place in 2020. Basically, the employees of a French defense industry wanted to gift the retiring employee with an amazing opportunity to take a ride in a Dassault fighter jet. Needless to say, despite all of his instruction, this 64 year old managed to self-eject during midflight. OMG!

Apparently the quick and dirty safety briefing failed to properly emphasize the fact that the black-and-yellow striped loop in the middle of the seat, between his legs, was not a grab handle but the trigger for the ejection seat. The good doctor's g-load recommendations were surely exceeded as pyrotechnics blasted a hole in the canopy and rocket motors fired the seat and its terrified denizen out into the slipstream high above the French countryside.
