Warren truss

[citation needed] The Warren truss consists of longitudinal members joined only by angled cross-members, forming alternately inverted equilateral triangle-shaped spaces along its length.

The Warren truss is a prominent structural feature in hundreds of hastily constructed aircraft hangars in WW2.

In the early parts of the war, the British and Canadian government formed an agreement known as the British Commonwealth Air Training Plan which used newly constructed airbases in Canada to train aircrew needed to sustain emerging air forces.

Two characteristic features were a triangle runway layout and hangars built from virgin British Columbia timbers with Warren truss configuration roofs.

The Italian World War I Ansaldo SVA series of fast reconnaissance biplanes were among the fastest aircraft of their era, while the Handley Page H.P.42 was a successful airliner of the late 1920s and the Fiat CR.42 Falco Falco fighter remained in service until World War II.
