re: #182 goddamnedfrank
An AC-130 accidentally lost control going inverted during test flight maneuvers two years ago. It had to be scrapped after G limit overload.
My first stepdad sold computers to McChord AFB and as a favor one of his contacts there got me some time on the 130 simulator in 1991. It’s an incredibly stable aircraft and while I’m no expert I suspect the pilot was doing something way off script.
One thing that comes to mind is a control surface failure.
