Jens Müller had one brother, the Norwegian movie director Nils R. Müller. Müller had already received a pilot"s license at age eighteen in 1935. Müller was studying in Zurich when World World War II broke out.
In May 1940 he arrived in England.
By 1942 he was an officer in 331 (Norwegian) Squadron at North Weald in England. On 19 June 1942, after completing a so-called "Roadsted" mission, his Spitfire Mark V (tail number AR298) was shot down by a German Focke-Wulf Fw 190 just off the Belgian coast after running out of ammunition.
He escaped the plane by parachute and managed to paddle ashore unseen in his inflatable dinghy after 66 hours. However, he was caught by a German sentry almost immediately.
In what later became known as the "Great Escape," which Müller had contributed to by constructing an air pump for ventilation of the tunnel, he was among the 76 prisoners of war who managed to escape from the camp (now: in Żagań, Poland).
Accompanied by Per Bergsland, he caught a train to Stettin in Germany (now: Szczecin, Poland), where they intended to meet one of Roger Bushell"s contacts in a local brothel. However, while there, they made contact with a Swede who offered to aid their escape, telling them to wait down at a pier in the harbour. After some time they realized the ship had left.
They spent half the night in a boxcar, slept the next at an inn, and on returning to the harbour the next evening, met two Swedish sailors who helped smuggle them past the harbour authorities.
The ship arrived in Gothenburg, where the two Norwegian pilots quickly sought out the British consulate. They were sent by train to Stockholm and were flown to Scotland from Bromma airport.
From there they were sent by train to London and shortly afterwards to "Little Norway" in Canada. Out of the 76 POWs who escaped, only three managed to reach neutral countries and freedom.
The third successful escapee was the Dutchman Bram van der Stok, who escaped to Spain with the help of the French resistance.
The remaining 73 escapees were recaptured. Adolf Hitler wanted to have them all shot, but Heinrich Himmler (or possibly Hermann Göring) persuaded him not to do this. Instead, fifty of the escapees were executed to make an example.
This was a serious breach of the Geneva Convention which constituted a war crime.
The remaining 23 recaptured prisoners were held in the custody of the Gestapo before being sent off to other camps. Of these, 17 were returned to Stalag Luft III, four were sent to Sachsenhausen, and two to Colditz Castle.
After the war, Müller worked for Det Norske Luftfartsselskap (DNL), one of the companies that merged into Scandinavian Airlines System. He retired in 1977. He died in April 1999.
Jens Müller wrote a book about his war time experiences titled Tre kom tilbake (Gyldendal, 1946).
