"When the war started, on 3 September 1939, 75 and 148 squadrons were the units flying from Harwell. The first burial at Harwell was that of Pilot Officer W. R. Ross (90913) who died on 14 November 1939, aged 27 years. His Bristol Blenheim, L1286, crashed at Blewbury at 11:30 hrs while he was ferrying the Blenheim from 5 Maintenance Unit from Kemble in Gloucestershire to 145 Sqn at Croydon in Surrey and was forced to land at Harwell due to low cloud and very bad visibility. He took off again immediately but crashed on the hills which were in low cloud. The Operational Record Book shows that P/O Ross crashed 1 mile from Harwell and was killed instantly.

Records also indicate that he served with 604 Sqn, and was the son of Lt.Col.Henry and Mrs Betty Ross. His funeral took place on the 17 November 1939".
