ozplane: I cannot comment on the attrition rate because that would require a knowledge of the number of hours flown/number in service etc.
My stats are brief and open to interpretation, but I reckon in the 5 years from Jan 1945 to Dec 1949 the RAF lost 62 Mossies that could be directly attributed to asymmetric problems on takeoff or landing.
The wartime losses might well have been much higher with the increased chances of losing an engine to enemy action.
