The Critical Drinker provides a good explanation of “The Rocketeer,” a movie from back when movies were actually fun. “Remember when Disney movies didn’t make you hate yourself.”
A little while ago I discussed Fictional Aircraft and mentioned an interest in eventually doing a US Bomber Projects style publication or three wrapped around them. A rocketpack might or might not be an aircraft, but it’d be a fun exercise to try to produce a realistic-sounding engineering explanation of the thing. Clearly this isn’t a “rocket” pack but a “jet” pack; trying to explain how a jet engine in 1938 developed enough thrust-to-weight to loft a dude skywards, and did it fuel efficiently enough (using alcohol, no less) to keep him up there for a substantial time, would be a bit of a challenge.
