10,000-Mile Training Flight
SEVEN aircraft from the Empire Air Navigation School, Shawbury, Shropshire, completed on August 11th a navigation training flight of 10,000 miles, which was accomplished in thirteen days. They left Shawbury on the morning of July 30th and flew to Gibraltar in eight hours, covering about 1,550 miles. En route they practised a new navigational method known as "pressure pattern flying" in the Atlantic, well to the west of the Iberian Peninsula. Pressure pattern flying is a collection of individual techniques based on well-known meteorological principles, coupled with the use of radar. Between Gibraltar and Castel Benito, in Libya, a distance of 1,500 miles, they executed other tests in the Mediterranean to the west of Sicily.
The next hop, of 1,750 miles, over the Sahara desert to Khartoum called for exact navigation in an area where there were no radar and few radio or landmark aids. Then the 1,100-mile flight down the Nile Valley to Almaza (Cairo) was accomplished in about six hours. The return was made via Castel Benito and Gibraltar to Shawbury, which five aircraft reached by 5.30 a.m. on the 11th. One Halifax landed at Shawbury at 2 p.m., but another was delayed at Gibraltar. One Lancastrian accompanied the formation of Halifaxes on the flight.
The Officer Commanding the mission was Wing Cdr. C. M. Dunnicliffe D.S.O., D.F.C.
