Question for the locals: I do not live in the USA, but I would love to visit someday and jump into some planes to take pictures. Is it open to the public? Does it require permission?
Also if you’re talking specifically about the planes in the boneyards, would not recommend doing that in the desert. You will find some other “visitors” like rattlesnakes, scorpions etc. that have made the plane their habitat.
Depends. Taking pictures in front of or around the planes is no problem, but majority are pretty much sealed off. That said, most of the bigger aerospace museums have several planes and helicopters with cockpit and cabin access.
