I read a book titled The Roswell UFO Crash: What They Don't Want You to Know by Kal Korff mainly because I thought it was another hokey "expose" of the incident cover-up.
It turned out to be a riot, for the author peeled away each witness like an onion and revealed that most of the witnesses were B/S artists, with the most egregious being the undertaker and his "child size coffins". The most unusual part of that whole thing was how memories grew sharper over the years, with new "remembered" items/events being added with each retelling.
I agree with this author that what was found was a radar reflector from a spy balloon, one of many, which the govt wanted to keep secret (spying in Russian air space to see if they had developed the A-Bomb).
The interesting sidebars were all those authors who climbed on the bandwagon, jumping to conclusions (of Olympic magnitude) or outright making things up, with Berlitz being an outright fraud.
IMO, the museum in Rosewell did a good job of being even-handed, which was a surprise to me as the city played it up for the tourists.
Rosewell is a good example of how a mystery can be created out of thin air and gullible people - much like the Bermuda Triangle nonsense.
Perhaps a balloon - but of a very different sort.
I’ve always been intrigued by a slightly different explanation. There was a different kind of balloon floating around back then; apparently the remains of one was found just recently.
(We have to remember that people in 1947 were living under very different circumstances, and had different references and concerns that we do, today. We have to interpret their responses within the context of their times and concerns.):
