I had some fun designing the Reindeer Mark II - my degree is in Industrial Design, and I spent a number of years drawing conceptual and real aircraft at one of my jobs, so I got to put some thought into this. Fans of Jimmy Stewart will recognize the basic design. Even though it might need the tail replaced every now and then, I'd love to see airplanes looking like this flying overhead.
The last panel is a bit of character establishment at reality's expense. Jeffrey was a big movie fan, although I don't recall his being so fond of Mr. Lucas's work. He definitely knew R2 D2, though.
