Olympic Airways Flight 411: The Day a Jumbo Jet Skimmed the Rooftops of Athens

29 Oct 2026, 03:17 by Stella Mazonakis · Greek City Times

On 9 August 1978, Olympic Airways Flight 411 brought Athens within metres of the worst air disaster in Greek history. The fully fuelled Boeing 747 lost an engine on take-off and skimmed the rooftops of the southern suburbs. Yet everyone on board walked away.

The jumbo was bound for New York. Its captain was Sifis Migadis, a Cretan veteran whose calm in the cockpit has become aviation legend.

A heavy jumbo on a hot day

The jet was SX-OAA, a Boeing 747-200 named Olympic Zeus. It was due to fly nonstop from Hellinikon airport to John F. Kennedy International in New York.

Conditions were tough. The temperature was 32°C, and the tanks held around 150 to 160 tonnes of fuel for the Atlantic crossing. Boeing’s later analysis, summarised on Wikipedia, put its weight at about 350 tonnes. That was just under its 353-tonne climb limit for the day.

Migadis, then 55, had flown for the airline and its predecessor TAE since 1948. Beside him sat co-pilot Konstantinos “Kostas” Fikardos, an equally experienced airman and a close friend.

Engine failure at the worst moment

Just as the nose lifted off, the No. 3 engine failed. Greek newspapers at the time reported an explosion and a huge flame. By then, the jumbo was too fast to stop on the runway.

Then a second problem struck. About nine seconds later, the crew switched off the engines’ water injection pumps. Boeing found the flight engineer had misread a warning light. As a result, the remaining engines lost vital extra thrust.

Migadis ordered the landing gear raised at just 35 feet. This went against the flight manual. However, it cut drag at a moment when every metre counted.

Over the rooftops of Athens

The 747 barely cleared Pani Hill in Alimos. After that, it sank again. It crossed Palaio Faliro, Nea Smyrni and Kallithea at roughly 55 metres, according to most Greek accounts.

Residents watched in shock as the giant jet tore television aerials from apartment roofs. One flight attendant later said she could see office workers at their desks in the Interamerican tower on Syngrou Avenue.

Inside, many passengers had no idea. Most were American tourists, and some reportedly thought the low pass was a sightseeing treat. They even took photos.

The captain could not risk a normal turn, because a banked wing might have stalled or struck buildings. So he held the jet level. According to Greek accounts, he aimed for Mount Aigaleo. If the plane came down, he hoped to spare the crowded suburbs below.

A breeze, a gentle turn and the sea

Eventually, the pilots lowered the nose to gain speed, and the engineer restored engine power. Around 2:05 pm, a light headwind gave the jet a few precious metres. That allowed a shallow turn away from the mountain.

The aircraft headed out over the sea and dumped fuel. Then it landed safely back at Hellinikon.

The next day, To Vima described hundreds of panicked calls to police from Kallithea, Nea Smyrni and Palaio Faliro. Relatives on the airport’s farewell terrace thought the plane had vanished among the buildings. Passengers left for New York at 5:40 pm on a second jumbo.

What Boeing concluded

In October 1978, Boeing sent its analysis to Greece’s civil aviation authority. It found no airframe or engine fault behind the poor climb. Instead, it blamed the accidental shutdown of water injection on a jet already at its climb limit.

Even so, the flight has gained mythical status. Greek accounts say every Boeing simulation of the flight ended in a crash. The case is also said to feature in Boeing training.

The pilot behind the miracle

Migadis was born in Heraklion in 1923. As a young volunteer, he fought in the Battle of Crete. He later joined the Allied resistance network Force 133 and escaped to Egypt in 1943. There, he trained as a pilot with the Royal Hellenic Air Force.

He retired from Olympic in 1981 and died in Athens in 1996. In a 1994 television interview, he admitted the crew had believed they were already dead.

“All of us who live after this are living by stealth,” he said. “But even in the hardest moments, there is a small hope that can give light, that can give life.”

How many were on board?

The figure most often quoted is 418 people: 400 passengers and 18 crew. However, contemporary reports differ. To Vima reported 370 passengers in 1978, while other accounts give 348 passengers and 20 crew.

Whatever the exact number, not one life was lost, in the air or on the ground. Nearly five decades later, Olympic Airways Flight 411 remains one of the great escapes in Greek aviation history.
