When I was in training for the F-117, one of our civilian instructors....Mr Klaus Klause related this. First night of Desert Storm, he was one of the first wave of F-117s going into Baghdad to hit the command centers located deeper than the radar sites on the border the Army AH-64s had hit at almost the same time. It wasn't really known is stealth actually worked. The F-117, being slapped together from miscellaneous odds and ends from the A-10, F-15A, F-16A and F/A-18A, it wasn't very eronomically friendly in the cockpit in some ways. As Klause is getting over Baghdad, the AAA that was filling the air in a barrage fashion starts shifting his direction. So he begins to slightly change course, which isn't recommended for a number of reasons, and the AAA keeps tracking him. Finally he really starts maneuvering, thinking "this stealth crap is BS...", finds his target, drops his bombs and gets the hell out of there. Crossing outbound, he's getting his systems back on-line "Fencing out", and notices that his position lights are still on and thats how the gunners were seeing him: visually. Back then in the 117, there were 5 different switches controlling 5 different external lighting systems, located in 5 completely separate places in the cockpit. On fence-in, he'd forgotten the position lights switch. A few years later, the USAF installed a single "all external lights- extinguish" switch on the left wall panel for ergonomic sake, aptly named the "Klaus switch".
