I've noticed that "slowness" when big piston bombers fly over. I figure it must have something to do with the time it takes to traverse their own length when nearby coupled with the rumble-rumble, somehow. Just weird.
I gather that after the war a large number of DC3s (C-47s) fell into civilian and commercial hands. Arthur Godfrey was given one and he used to commute to Hawaii in it. There was an incident where he buzzed a control tower and got in trouble.
I believe Senator Barry Goldwater had one, but I can't put my finger on a referent. He was kind of a tech nut, owned an early IBM 1620 computer and was a ham radio operator.
