I happened upon this WWII-era video and it reminded me of the incident where the 733rd was part of a decoy operation. From my map (originally from the book, “Ghosts of the ETO”):
02 November – 10 November 1944: The 733rd was part of ‘Operation Dallas’, which made extensive use of inflatable decoys and flash simulators. On 08 November German planes circled the area to survey it. The men weren’t sure if the decoy worked or failed.
