Japan's Mitsubishi Ki-21 "Sally" bomber added

The Japanese combat aircraft had much success against the inferior defenses and equipment of the Chinese in the early years that lead up to World War II. Unfortunately for the Japanese crews this lead to the attitude that these early designs would be adequate for the upcoming war with the United States and Britain. The Mitsubishi Ki-21 was such a combat plane. It was kept in combat much longer than it should have been.

I've added a new page for the Ki-21.
