Probably because--get ready for this--it's classified information!
Why don't believers ever consider that the blacked-out information might actually be a matter of national security? That maybe it might be bad for us if the Russians or Chinese or God-knows-who found out what we were doing in the 40s?
Easy, dawg. I don't think I'm any kind of hard-core believer, so don't put me in that group, thanks. It's just that all that blackout for a cheapass balloon sensor, surely hugely outdated by now, seems kind of strange. I'm not really sure how it would be bad for us if the Russians - no longer the USSR - or the Chinese found out what we were doing in the 40's. Hell, the Brits and Americans were so badly penetrated like a decade later that one wonders what the point would be. I wonder if it would be worth looking at the blacked-out pages themselves to see if there's any kind of grammatical room for something like that.
Given that this comes from a place called "Secrecy News," I'm going to venture a guess and say no. Just as I'm skeptical when I hear that a group called "Noah's Ark Ministries" claims to have discovered that mythical boat. You have to consider the source.
I do; but I'm also looking to see if it's so in other sources.
But even if we allow that files have been destroyed, it does not mean that the government is hiding alien technology. It might simply mean (if true, which it almost certainly isn't) that they don't want information getting out. To make the leap from that to "they're hiding aliens!" is ludicrous.
Well, actually that's the competing hypothesis, so it's not that ludicrous. This iss the counter-argument.
I presume by this you mean an alien spacecraft? It wouldn't. Because it doesn't exist. Well, I'm sure there's a planet somewhere with a spacefaring alien race, so let me amend: There have been no alien spacecraft on Earth, so don't worry about it.
Ah-ah-ah: calm down. Put it this way: if FTL travel is so insanely impossible, why is there so much interest in it? It can't work? Bit too early to completely count it out: they laughed at the natives who said they'd seen Columbus pull up in his ships too. Let's have a gander. What's to lose?
