I have seen a plane which retracts its gear into the fuselage. On leg goes forward, the other back. Racking my brains! it must be either a jet fighter (to maintain profile) or very light (to maintain CoG). I hope someone solves this soon!
I have seen interviews with crash survivors who recommend keeping it in your pocket. Because you will not remember to grab it when exiting the plane and so it goes up in smoke unactivated if the plane burns.
I think you could sign temporary MR on a sheet of paper to cover a flight. But I am no lawyer! Your licence/medical arrives digitally, can you retrieve it from archived email?
And as I posted earlier, I use Google but a description in words to search. Sometimes I waste (enjoy) an hour doing it. I agree image search is cheating, but the few times I tried it for an aeroplane it always found a Cessna 172.
