This is a 20-year-old single witness account, but with (reported) supporting documentation. Vandenberg AFB is just up the coast from Los Angeles, California.External Quote:
LUNA: My next question would actually be for Mr. Graves. Can you please explain to me in detail the event that occurred at Vandenberg Air Force Base?
GRAVES: Certainly. In the 2003 timeframe, a large group of Boeing contractors were operating near one of the launch facilities at Vandenberg Air Force Base when they observed a very large, 100 yard sided, red square approached the base from the ocean and hover at low altitude over one of the launch facilities. This object remained for about 45 seconds or so before darting off over the mountains. There was a similar event within 24 hours later in the evening. This was a morning event, I believe, 8:45 in the morning. Later, in the evening, post sunset, there were reports of other sightings on base, including some aggressive behaviors, these objects were approaching some of the security guards at rapid speeds before darting off. And this is information that was received through one of the witnesses that have approached me Americans for Safe aerospace.
LUNA: Was this documented in any official form, whether it was a police blotter?
GRAVES: Yes, they had official documentation and records from the event that the witness held over the years.
LUNA: And I'm not going to ask you to do right now for time reasons. But you'd be able to sketch what it was, correct?. And you've have you seen that before on any other equipment and/or during your flight time.
GRAVES: I have not seen what they've described, this object was estimated to be almost the size of a football field. And I have not seen anything personally that large.
I've driven past it a few times on PCH (Pacific Coast Highway, Hwy 1). Unlike "Area 51", it's not that isolated. However, Graves says "a very large, 100 yard sided, red square approached the base from the ocean and hover at low altitude over one of the launch facilities". This suggests something like the space launch complex nearer the ocean, or perhaps further north.
The area is surrounded by mountains, so "darting off over the mountains" could be any direction over land.
There's not a lot you can do with such a vague description, but maybe more info will come out later.
