I was visiting the library in East Hartford today, which boasts having an "aviation museum" I'd never actually managed to find. Turns out it's on the last floor, but I show up, and the lights are off. I flip on the light switch, see nothing but a few photo exhibits, go around the bend, and find a beautifully restored R-1830 Twin Wasp radial engine.
A couple more photo exhibits, another bend, and I find another immaculate aircraft engine, this time a J57 turbojet revealed in cutaway.
Both of these engines are in better conditions than the same types displayed at the New England Air Museum, but it looks like nobody even knew they were there. I find it both fascinating, and a little odd, that Connecticut is so proud of it's aviation heritage that it displays jet engines in it's public libraries.
