Martin B-26 Marauder
Despite nicknames like the "Widowmaker", earned due to the tricky landing and takeoff behavior of its early models, the Marauder had the lowest loss rate of any combat aircraft of WWII. Its small wings gave it poor low speed behavior (it landed at about the same speed as a modern jumbo jet), and it never was very popular with its crews. It was soon replaced by the Mitchell in the Pacific, where the improvised island airfields demanded shorter takeoff runs.
