An airline has allegedly warned pilots after rumours emerged some were sharing explicit footage of colleagues engaging in sexual acts while on flights.
According to the Sun Germany's Condor Airlines have told pilots they could face receiving the sack as well as criminal charges if they were seen to be taking and distributing X-rated images.
Those caught could face up to two years in jail.
IBT Times reported pilots were allegedly filming stewardesses performing sex acts before trading footage as "trophies".
A Condor spokesman said: "We have been clear with our colleagues that there is no place in our organisation for this kind of inappropriate behaviour.
"We are rigorously pursuing any allegation. We will of course initiate disciplinary and legal measures if we find that there is any substance to any kind of claim".
Condor was launched in 1956 and flies to 80 destinations across Europe, America, Africa and Asia.
