Full size models in WWII


I wonder what went through the Germans’ minds when they failed to hear a boom and found that laying out there? I also wonder if someone ended up in prison or dead for that embarrassment.

I recall reading a comic - Not a Commando - the drawings were iffy - decades ago, that had this incident as the main story, except it was an Italian project in North Africa. Had wondered if it was true, the fake bomb dropped on a fake airfield seemed the appropriate response.
