Dr Jesse Marcel Jr is a patriot and a very fine man. But he was 10 years old when his dad mistakenly told him he was looking at debris from a flying saucer.
This subject has been thoroughly debunked. No alien craft crashed at Roswell, NM in 1947. It would be a lot more interesting world if it had actually happened, but it did not.

Thoroughly and skillfully debunked, but not proven false. The debunking is just as much hearsay as the claims themselves, and the article you referenced is hardly unbiased - the number of third-party straw-men arguments, implicatory conclusions and yes, hearsay "facts" pads the hell out of the thing.
I believe, though he was 10 years old, Jesse reported what he actually experienced, and his dad was silenced by the cover-up. The military blew it - they admitted it before they denied it, and the absurdity of the weather balloon story just doesn't even remotely pass the smell test.
But what I have never believed is that a ship just "crashed" because of an electrical storm, after travelling from who knows where. We either figured out how to shoot it down, or "they" arranged it as a sacrifice to try to get us to admit it was real, or to transfer technology to us, or both.
But no matter what, I really hope they aren't galactic proctologists.
What unmitigated cluelessness.
