the A-10 is actually a stolen WWII German design.

Correction: a hungarian design from 1944.

Except for slightly W-shaped wing, the plane looked just like the A-10.
It was powered by two Jumo or BMW made 8kN turbines. It was 3/4th
completed, when the factory was overrun by the front. Supposedly the
plane's parts and drawings were captured by the USA and hauled overseas.

The three-view drawing of the plane was featured on the back cover of a
1976 copy of the hungarian monthly paper "Repules". It was quite unusual
for a communist state-run paper to feature a nazi plane at that time.
