They said it wasn't shot down, 'cause the picture shows it all in one piece, no blast damage, no scorch marks or bullet holes. Makes sense.
The undercarriage is hidden in the photo the Iranians released which suggests "The lack of crash damage would indicate the standard UAV flight-termination procedure after an airborne mishap of going into a flat spin."
That's cool. A flat spin slows the drone down enough to recover it in one piece. Just what you need on a peacetime test range. It's nice to have a chance to fix what broke and fly it again. Not sure if that's what you want in wartime. I think it ought to do a power dive into the ground leaving a big hole. And a lot of scrap metal.
Aviation Week said the nobody was very concerned about compromising secrets. They claim the payload was a "full motion video sensor" aka ordinary TV camera. As far as the air frame and engine go, the experts claim there is nothing new there. Right.
