"Between June and the end of the year, 398 Lockheed and Martin medium bombers--including 120 B-34's, 153 A-28's, 45 B-26's, and 80 A-30's--
were ferried to British forces in Africa by crews of Pan American Air Ferries or by American and British military crews."

B-34 = Lockheed Ventura
A-28 = Lockheed Hudson
B-26 = Martin Marauder
A-30 = Martin Baltimore
Methinks it might be a Ferrying accident to one of these...
