Description

The question was something along the lines of, “How did this happen on a military base and no one but these three contractors saw the football sized UAP?”
Vandenberg SFB is a huge base. LF-21 is on the north side of base. The area around LF-21 is very remote and there is hardly anyone there… only contractors and security forces. LF-21 is on a large hill that over looks the ocean. There is a cliff too.

"In the 2003 time frame, 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 approach the base from the ocean and hover at low altitude over one of the launch facilities," described Ryan Graves. "This object remained for about 45 seconds or so before darting off over the mountains."

The UAP in question would not have been seen by anyone on base except for these contractors or anyone in the immediate area due to the remoteness of the area.
Also it happened around 830. Most people were at work. Not a lot of traffic on base at that time usually.

Got a popped tire doing this but it was fun and a beautiful sight to behold.
