Ha! Yes I could see that happening. The gentleman I spoke of would use his umbrella getting out of the plane. It was a huge, multicolored tour guide style umbrella, that looked even bigger over his maybe 5'1" frame.
The plane would come to a stop, you'd see the canopy wiggle and then the umbrella poke up through the opening. Then the huge thing would blossom and cover nearly the entire cabin area. He'd climb out then close the canopy before clamoring down off the wing.
Don't think I saw the procedure for boarding the aircraft in the rain, though I'm quite sure he would not have been above simply starting up and taxiing it out of the hangar.
