Hehe, not exactly a glorious story:
"The first B-339B (flight tested before delivery under the US civil registration of NX-56B) was on its way to Belgium when the German blitzkrieg overran the Low Countries, and the ship carrying the plane was diverted to France. This plane was apparently later captured by the Germans and was test flown.
The next six B-339Bs were diverted to France. They were sent to Canada and loaded aboard the French aircraft carrier Bearn, along with a batch of Curtiss SBC Helldivers and Curtiss Hawk 75A-4s that had been purchased for the Armée de l'Air. The Bearn sailed on June 16, 1940 and was in mid-ocean when France fell. The carrier was diverted to Martinique (a French possession), and the six Brewsters along with the other aircraft aboard were unloaded. They sat for months parked out in a field while international arguments took place about their true ownership and their ultimate destination. There was some concern on the part of the United States government that the Vichy regime in France might become an active German ally and that these aircraft might present a threat to the nearby Panama Canal. Finally, the planes sitting on Martinique were destroyed on the ground by sabotage, probably by Allied agents to prevent them from falling into Axis hands."
Aren't there French markings on that wreck? ... I could be wrong.
