Mosquito TH984: Flew into ground on overshoot 1.5 miles south of RAF Waddington 20/12/1949.
The crew had overshot four attempts elsewhere and then diverted to RAF Waddington. The pilot carried out an approach for familiarisation from which he overshot into the circuit but by this time he was under pressure and with fuel running low, he initiated another overshoot but the aircraft crashed in a level attitude 1 1/2 miles from the runway at Coleby Heath, Lincolnshire.
