Restoring a World War I DH-4

0

When the U.S. entered World War I in 1917, it had no suitable combat aircraft so the British-designed DH-4 was adopted and manufactured in volume in the U.S. Because the 400-HP Liberty engine was used, the American-made DH-4s were called Liberty Planes. Very few survive to this day, but in this AVweb video shot at AirVenture, we offer a detailed tour of the airplane and how it’s being restored.
