What a great site, thanks!

Actually, the Apollo 13 sighting (sorry, I don't remember it) may be
another movie anachronism, as well.

My father was a NASA engineer in the early sixties, and I have the
impression that there was a strong tendency among his colleagues in
those days to flaunt the fanciest SR they could afford on their
desks. It was, of course, a status thing.

So while in the movie Apollo 13, the movie actor engineer may have
had a relatively simple rule, in real life, the engineer the actor
played quite probably had something better. As far as the movie
makers are concerned, though, slide rule equals
engineer/brainiac/math geek, and the prop they used was close enough.

Anyway, my point about Sky Captain: the character Dex Dearborn is a
comicbook-loving genius scientist engineer who creates amazing things
like death-rays, and fighter planes that instantly convert into
submarines, etc. on a virtually weekly basis. What kind of SR would
Dex use? A simple Mannheim?

Nope. He'd definitely have some wizbang of a slipstick, with multiple
slides, and dozens of scales, reverse polish notation, andÂ… you get
the idea.

Rich.
