"Aircraft of the Great Raid"

"The Hudson was fully repainted in a USAAF scheme comprising light grey undersides and olive drab upper surfaces. With the American "Star and Bar" insignia applied as a finnishing touch, the Hudson was intended to masquerade as a Lockheed PV-1 Ventura"

Note "intended". The camp was actually buzzed by a P-61 Black Widow.

Rego given as:
