In this World War I photo from the National Library of Scotland, an airplane has crash-landed on the roof of a building. The description notes:
This photograph of an aeroplane which has crash-landed on the roof of a building is a dramatic illustration of the flimsy nature of the early fighter planes. There is remarkably little apparent damage to the roof but the wood and fabric framework of the plane's tail has folded up around a chimneystack.
Even as late as the spring of 1917, the Royal Flying Corps were losing about 50 planes every week. When possible, as appears to be happening in this case, the wreckage was salvaged and re-used.
