Olympic Airways Flight 954 strikes a mountain outside of Keratea, Greece, killing 90 people in the worst crash of a Douglas DC-6 in history.

Olympic Airways Flight 954 was a Douglas DC-6B aircraft that crashed into a mountain near Keratea, Greece, on December 8, 1969. All 85 passengers and 5 crew on board died in the crash.

The Douglas DC-6 is a piston-powered airliner and cargo aircraft built by the Douglas Aircraft Company from 1946 to 1958. Originally intended as a military transport near the end of World War II, Douglas reworked it after the war to compete with the Lockheed Constellation in the long-range commercial transport market. Douglas built over 700, and many still fly in cargo, military, and wildfire control roles.
