Okay, that the facility was closing - EDIT: or that the operations were shutting down - is the same information I got back in 2015 from the retired AF man who said he ran the place. He told me he was trying to sell some of the equipment.

BUT, as far as "aliens" go....I'm telling you straight up, I stood and watched a very, very, VERY large craft slowly lower down into Sac Mts. early one morning. It wasn't right at Sunspot, it sat down between Sunspot and Alamo, further back into the mountain range.

Perhaps whatever that craft was didn't have diddlysquat to do with the observatory, but I know what I saw, and it was more than remarkable.
