Is this typical for most aircraft? This is a Learjet C-21A, the other stratotanker I had seen in Topeka seems to have exposed screws as well, but Phillips head. I just find it interesting, I don’t actually mind the exposed fasteners. The only planes I’m up close to are like these, on display stores outside. More later.

This and more are on display and open to the public in front of Scott Air Force Base in Shilo, IL just east of St. Louis.
