What is a "Boeing or Airbus ignition key"? I ask in a sprit of pure enquiry...
The Russian aircraft all had locks, when I used to look after TU154’S we had to wait for the engineer to come down and unlock the hold doors so we could offload the baggage. I also remember not being able to load an IL76 until the engineer turned up with the key to unlock the front door. I don’t think they had ignition keys though
