Dornier Do-13

The Dornier Do 13 was a short lived 1930s German bomber design.

It was the designation given to the aircraft resulting from attempts to improve on the Do 11.

However, only a few were built, because the design changes caused serious problems, with many of the first flights ending in crashes.
