I don't think you could count on an airplane being shot down, then impact automatically destroying say, a bombsite. There would be enough to salvage I would imagine for German engineers to start piecing it together.
Plus on the way down, the body could break apart, separating the nose from the part of the plane that would burn (re; Pan Am flight over Scotland and nose section photograph; the poor pilots who rode that baby all the way down)
I'm not sure I believe this 100% just yet. If all the planes were independently dropping bombs based on their own calibration, why the stories of other planes dropping when the lead drops.
Also, even though this is a game. the drones drop when the lead plane drops. Like one plane having the sight, the others dropping when the lead goes.
Don't know though, might be completely wrong. Maybe they all had them. Why would each plane have a bombadier otherwise..right?
