I grew up in New Mexico, about 160 miles from Roswell. 7 years before I was born an airborne object crashed on a ranch near Roswell and Corona, NM.
What it was, well, that has been up for discussion all of my life. It could have been a top secret surveillance balloon ... the official government story, or it could have been aliens, as some people believe.
Heck if I know what it was. I first heard stories about the 3 foot tall aliens that crashed, all deceased except for one, at school in the early 60's ... decades before books and the TV show.
I just heard that Roswell has a UFO shaped McDonald's. I don't know when it was built, but how cool is that! I want to go!
