Airco DH.4

 

 

The Airco DH.4 was a British two-seater biplane of the First World War. It was the first British two seat light day-bomber to have an effective defensive armament. The DH.4 proved a huge success and was often considered the best single-engine bomber of the War. It was flown by a number of famous British and American aces, such as Frederick Cotton and Charles Bartlett.
