It should be mostly undamaged.

Either captured, or taken after forced landing, or similar. Something like the Hainan incident would count. https://en.wikipedia.org/wiki/Hainan_Island_incident

Even if the pilot has a chance to manually destroy sensitive aspects of the plane before being taken, as long as the exterior is mostly intact it would count. Even a crash which the pilot walks away from would likely result in a plane in good enough condition to count.
