The bombing range at the Ashley Range in the New Forest had a concrete target about 20 ft × 20 ft (6.1 m × 6.1 m), to be bombed preferably from the optimum height of 22,000 ft (6,700 m). PB955 was loaded with the Grand Slam to be flown by Group Captain H. A. (Bruin) Purvis; bad weather led to two failed attempts to bomb due to mist obscuring ...
