The airplane most famous for being used in the Dolittle Raid in WWII. Normally a land based plane,some of these were stripped down to save weight so they could take off from an aircraft carrier yet still couldn't carry enough fuel to return to the carrier after their raid on Japan, the first by the US on Japan. They flew on to China where many of the pilots survived though some were killed and others captured by the Japanese. I think it was about ten planes that took part.
