Olympic Airways Flight 411 was a flight from Ellinikon International Airport bound for John F. Kennedy International Airport and operated by Olympic Airways using a Boeing 747-200. On August 9, 1978, the flight came close to crashing in downtown Athens. Despite maneuvers near the edge of the flight envelope, none of the 418 passengers and crew suffered serious injury. Boeing reported that there was an "engine shut down" while taking off. Based upon review of the flight data recorder, Boeing concluded that nine seconds after takeoff, the flight crew had turned off the water injection pumps in response to warnings, which reduced thrust. Turning off the pumps when the plane was in takeoff climb limited the plane's ability to climb. Boeing states that thrust was increased manually after 325 seconds and then the plane climbed normally. Captain Sifis Migadis and Captain Kostas Fikardos managed to keep the aircraft in the air at an extremely low altitude below minimal speed. All Boeing simulations of the flight resulted in crashes.

Cape Colias (Ancient Greek: Κωλιὰς ἄκρα, Kōliàs ákra) was a promontory on the coast of Attica in ancient Greece, located about 20 stadia from Phaleron. The cape is most commonly identified with the modern promontory of Agios Kosmas. The site was historically significant as the location where the wreckage of the Persian fleet washed ashore after the Battle of Salamis, and it was home to a notable sanctuary of Coliad Aphrodite and Genetyllides. The location was also known for high-quality clay used for pottery.
