THY DC-10 in 1973 - a charter carrying rugby supporters from Paris (to London?).
Door locks failed to engage on rear cargo door. This is why the DC-10 lower cargo doors have windows over the locks so their engagement can be verified. Other doors, like Main Deck cargo doors on 757 SF, have similar viewing windows. Main reason THY DC-10 crashed was due to cabin floor collapsing. Subsequent mods to the DC-10 and other types introduced vent panels in the floors.
