the yanks had Saturn V
the british had concorde
the only reason concorde was retired was because the French can’t maintain their aircraft
the French concorde when it crashed had 4 main problems
1 wreckage of other aircraft on the runway
2 concorde was OVERLOADED and the pilots knew it and they decided to operate outside its envelope
3 the engineers maintaining concorde had left a critical part off the undercarriage – after the crash a team went over to the hanger that day and discovered the spacer for the wheels still hanging on its rack. the spacer stopped the wheels going askew, the tyre marks of the problem was still to be seen on the runway, concorde was already on fire, overloaded with one set of wheels effectively locked and dragging along the runway (they smashed some of the lights on the runway)
4 the engineer on board decided without telling the captain to shut down the burning engine thus reducing airspeed and making sure that it could never gain enough speed to gain control. a breach of protocol.
(5) it was widely discussed at british airways that day in the engineering section that the French had left the fuel lines loose and thus fuel pouring out the engine was the cause for the fire
basically air france fucked up so badly it wasn’t funny – when I discovered all these things I decided never to fly with them
