Pilots of F22, the Swedish UN squadron in Congo, posing in front of one of their jets. At the end of the mission in 1963, seven of the nine J29B fighters, including 29365 / I, were blown up by the Swedes as the non-afterburning J29B was being phased out and the costs of bringing the aircraft home could not be justified.
