Józef Jeka was born in Tupadły (present-day it is part of the town Władysławowo).

[2][circular reference] Two Józef's brothers, Alfons and Stanisław belonged to the Pomeranian Griffin.

On 1 August 1937 Józef Jeka entered the Non-Commissioned Officer's School for minors.

Two months later, the Allied front reached his hiding place and Jeka returned to his unit.

After the Second World War ended, Jeka stayed in the RAF and served in Allied-occupied Germany.

He flight-tested the Lockheed U-2 aircraft, and flew missions over Central and Eastern Europe.

The mission was cancelled, as on 5 March 1953, the Polish pilot Franciszek Jarecki landed his MiG at Bornholm.

In the late 1950s Jeka served in the Angkatan Udara Revolusioner (AUREV) air force of the Permesta rebels on Sulawesi in Indonesia.

On 13 April 1958, Jeka was the pilot of an AUREV Martin B-26 Marauder when it crashed on take-off from Permesta's Mapanget airbase.

Jeka, his Polish navigator Jan Iżicky, and his Indonesian radio operator / observer, Minahasan, were all killed.
