Opinion on Area 51 whistleblowers?
Don't take it too seriously. A similar question came up on Ask a few years ago. There we learned that Area 51 is redundant. They're up to Area 57 now.
I watched a TV show on this and there is definitely something the government wants kept secret. The workers are flown in by special plane every day and flown home in the evening. The TV crew followed one of these people home and he opened the door a crack but refused to answer any questions, he looked genuinely scared. I don't think we will ever find out what happened there.
