The U.S. Navy's Curtis F9C Sparrowhawks are some of the coolest planes ever; sleek little biplane fighters that operated from the rigid airships of the USN.
I'd never realized that they were in service for almost three years and that they performed over 100 successful midair "hookups" in their first month of trials alone. According to the pilots, once you got the hang of it, it was easier than lining up a landing on a regular airstrip. I wonder if there's a unit history published someplace? Or hopefully one of the fliers left an autobiography...
It would be a shame if every single Sparrowhawk pilot had passed away without any of them leaving a memoir; they were sole eyewitnesses to a very unique little chunk of aviation history.
EDIT: A search for deck plans so I could get a feel for the hangar arrangements turned up a discussion at a forum called "airshipmodeler.com", which proves that there truly is an internet discussion forum for every interest under the sun. Do you reckon they have arguments about "Which blimp for bear?"
