When I joined 39 Sqdn in 1952 we were given the history of the sqdn which was formed as a home defence sqdn to combat the German airships. Seemed apt that it was a nightfighter sqdn then, one of the very first. It is extremely hard to imagine the tenacity and endurance needed by those men, flying, in open cockpits, at extremes of the aircrafts performance, in order to combat these huge airships. Then they had to find a safe night landing 😮
