A E G G IV - WWI German bomber 

WW I bomber at Canada Aviation Museum in Ottawa, Ontario.
from their website:
The Allgemeine Elektrizitäts Gesellschaft (A.E.G.) G.IV bomber went into general use with the German Air Force during 1917. Because of its relatively short range, the G.IV served mainly as a tactical bomber, and operated close to the front lines. The G.IV flew both day and night operations, but, as the war progressed, was restricted increasingly to night missions. A.E.G. units operated in France, Romania, Greece, and Italy.
Many night operations were nuisance raids with no specific targets, but with the intention of disrupting sleep and perhaps doing some damage. The crew was equipped with electrically heated suits and the aircraft fitted with radios. The G.IV is the only surviving aircraft displaying the distinctive German First World War night lozenge camouflage pattern. Although the rear gunners cockpit is on the top of the fuselage, his position was equipped with a hinged window in the floor for viewing and fending off pursuing aircraft

The G.IV is a unique specimen - the only surviving twin-engine German First World War aircraft. It was shipped as a war trophy to Canada in 1919; its movements over the next 40 years (two 260 hp Mercedes engines were lost) were not well documented. The aircraft was stored in a warehouse operated by the Canadian War Museum in the 1950s. In 1968-69, it was restored by No. 6 Repair Depot, RCAF, with 160 hp Mercedes engines in place of the correct powerplants
