I bet yr sister & I read the same Axios article. I'm not smart enough to come up with this type of analysis on my own. 😀

What details did the Air Force guy give about his abductions?

The usual ones. The aliens were bug-eyed humanoids with wrinkly grey skin. There were machines emitting eerie green light. He's convinced he was abducted twice: once as a kid and once as an adult. He really seems to believe it! I have to say, he was a bit off in other ways, so I'm not sure I believe it. 😀
