I made an IBM parts delivery into a building at Moffet Field once near where one of those was parked. It had 12 guys with MP5 and M4 standing around it. They had a Humvee with more armed guards parked at the end of the runway where Highway 101 passes near. It probably had something to do with Onizuka and the Blue Cube. Those and variations were always coming and going from Moffet in the mid 90's.
