Engine Failure in Thunderstorm Over the North Sea

An engine failure during a thunderstorm flight over the North Sea brought Hans Bieri, as a young professional pilot in Germany, to the brink of life and death. What began as a routine passenger flight to the island of Borkum developed into a dramatic fight for survival over the raging waves. In his autobiography «Ruf vom Himmel» (Call from Heaven), Bieri describes this shattering experience that put his faith to a severe test.

Why did I volunteer for this death flight?

"Why I volunteered for this flight, I still don't know today, it was pure suicide," Hans Bieri recalls of that sultry afternoon in Emden. Thunder was already rolling ominously toward the sea when the chief came into the flight office looking for a pilot.

A government official urgently needed to be flown to Borkum. All other pilots remained silent – the weather was too dangerous. But Bieri stood up and volunteered for the flight that would prove to be a "flight of no return."

The passenger with his briefcase had no idea what he was getting into. Three minutes after takeoff they were already in the air, while a pitch-black thunderstorm front built up ahead of them.

Into the black hell

The clouds literally spiraled upward as Bieri flew toward the coast. Now would have been the moment to abort the flight. Instead, he radioed: "Overflying coast" – and steered directly into the black thunderstorm wall.

One minute later he found himself in hell: visibility absolutely zero, heavy rain, the aircraft rocking back and forth like a feather. Thunder and lightning alternated within seconds, while the deafening noise drowned out everything.

Bieri knew about the danger of carburetor icing during rapid air cooling. He performed the carburetor check and pulled the lever for warm air. But precisely at this critical moment, the unthinkable happened.

Mayday over the raging North Sea

The engine failed. The RPM dropped almost to zero. Immediately Bieri issued a mayday: "Call sign: DEGNU, engine failure over the North Sea, between Emden and Borkum."

With a quick movement he reached under his passenger's seat and handed him a life vest. "Put it on!" he shouted through the noise. The government official's face had turned ashen gray, pale as a corpse.

There was no time for his own life vest – a fatal situation, because Hans Bieri could not swim. Below them the North Sea raged, above them the thunderstorm, and the engine was dead.

When faith becomes the only hope

In such moments between life and death, a person's true character is revealed. Hans Bieri, whose life conviction culminates in the words: "Jesus Christ – the beginning and the end, the center of my life, my rock of salvation," faced the ultimate test.

What happened in the next minutes over the raging North Sea, how the young pilot fought with the failed engine and whether rescue came – these dramatic details Bieri describes in his autobiography «Ruf vom Himmel» (Call from Heaven) with shattering honesty.

It is experiences like these that shape a pilot and show that sometimes only faith stands between despair and hope.

Brief Q&A

What happens during an engine failure over the sea? During an engine failure over the sea, the pilot must immediately send a mayday signal and equip passengers with life vests. The aircraft will transition to a gliding descent, where altitude and distance to the nearest landing possibility are crucial for survival.

Why is flying through thunderstorms so dangerous? Thunderstorms bring extreme turbulence, zero visibility, hail, and the danger of carburetor icing. Rapid air cooling can lead to engine failure, while lightning and severe up- and downdrafts can make the aircraft uncontrollable.

Some flights teach us more about life than years on the ground – especially those where we learn that our control is limited and trust is sometimes all that remains.
