Not in the least - I'm usually all about the Age of Sail. I kept my research really constrained for this one, by my standards. I knew I wanted them to survive a bomber crash in the Pacific, so I started looking at bombers. I found an actual B-24 crash to base mine on, & read the pop history book on it up to the crash itself & the life raft bit, and stopped reading when they were captured by the Japanese because my guys got rescued. Then I did a little bit of web searching to understand the layout of the B-24 with the different crew stations and crash exits. And that, aside from a few side trips into Golden Age comics and how the hell did a Mae West life vest fasten and how waterproof were their watches, was it.

Luckily I won't have to become an expert on WWII for their later stuff either. I'll have the much richer field of midcentury Manhattan, plus gay/subcultural history therein, to play with. (But NOT the Beats. I don't LIKE them and nothing says I have to play with them.)
