Ruby did not adapt to life in Czechoslovakia and Kuttelwascher's air force service there, and in January 1946 she returned to England. Kuttelwascher became concerned about the growing power of the Communist Party of Czechoslovakia under Soviet patronage in the Third Czechoslovak Republic. He applied for a visa to return to the UK, which was eventually granted. On 21 May 1946, he resigned from the air force and five days later, on the day of the Czechoslovak general election, returned to Britain.
