Geez, this brings back memories...
"Doors", No one ever questioned why Lewin always had a very heavy satchel in one hand and all the books out of it tucked under the other arm, lol.
"Rover 5", I saw Kerop the other day, he's still the same... "Hey boy, I flat you down".
I could go on with many anecdotes,
Don't forget the white caps to go with the white overalls and you'll need "Mike" buses operating between the hangars and the SIT.
Everything old is new again...
