Why bother with espionage, just pull a chair and wait. One will fall out of the sky somewhere. The airframe is just a box to carry the gubbins. Now someone else has the latest gubbins. Any fool (sorry, but its true) can build an airframe. Very few folks can build gubbins. That is where the issue lies.
Hopefully the gubbins were protected, if not we just gave the folks who hate us a wonderful Christmas gift.
