| The Airco DH4 was a two-seat bomber
with a clean, tractor layout and a non-rotary
engine that improved handling and stability
as the torque produced by in-line engines
was nowhere near that of a rotary engine.
It was the first bomber designed specifically
for day light bombing. It first served
in 1917 and was withdrawn from service
in 1932. |
