"In his debrief comments, Dave, his WSO and the two other crews stated the object had initially been hovering like a Harrier. They described it as uniformly white, about 46 feet long (roughly fighter-sized), having a discernible midline horizontal axis (like a fuselage) but having no visible windows, nacelles, wings or propulsion systems.
As Dave was pulling for nose-on and trying to get a dogfight lock with his radar, the AAV tightened its turn, “lift vector on, then aft” as Dave described, passed behind his tail and accelerated away at multi-Mach speed. Dave immediately queried Princeton for a snap-vector but the SPY-1 radar had also lost the contact. The first calls from Princeton were “picture clean.” A few moments later Princeton came back with, “You’re not going to believe this, it’s at your CAP.” Princeton had picked up the AAV hovering at 24K at the assigned Lat/Long Dave had used earlier during training as his orbiting point."
