I always had a hunch that Bob Lazar most likely did work at area 51  as 
a janitor or service person of some kind. 

John Lear:
On March 21, 1989 Bob asked me if I wanted to watch a saucer test flown and I said sure, when?. He said they are going to test fly tomorrow night just at sunset. He and I, Gene Huff and Bobs wife drove in my motorhome up to the back road into Groom Lake and parked just outside the restricted area. Just after sunset the saucer came up from behind the mountains and did some gravity jumps. I got a good look at it with my 8 inch Celestron after it had finished performing and was gently and slowly descending. It 
looked like a flying saucer oriented about 30 to 40 degrees with resepct to the horizon and was 'glowing' yellow or gold color, actually 'radiating' the color. I watched it for about 15 seconds before it settled back down behind the mountains. The was March 22, 1989. George Knapp went with Bob the following Wednesday and filmed it. The following Wednesday after that, April 6, 1989 was when we all got got. Yep, they must tell all them janitors, "Hey Guys, don't tell anybody, we are going to fly one of the extraterrestrial flying saucers Wednesday night.
