| Histoire résumée | B.A.C. Ltd was registered as a Limited Company on 4 March 1931; directors were C H Lowe-Wylde, K Barcham Green and Mrs Sheila M Green. Around this time Lowe-Wylde was developing the principle of launching gliders by towing them using a powerful car. Giving demonstrations around the country, his Bentley, driven by Mrs Green, was able to launch him to a height of 300ft, thus making hill sites and bungy-launch teams unnecessary. A school of auto-towed instruction was started at West Malling. The Sopwith Dove G-EBKY (now with the Shuttleworth Collection) was also used for aero-towing. An improved version of the B.A.C. III appearing in April 1931 was the B.A.C. IV with longer, tapered wings. One was sold to Mr C M C Turner of the Channel Gliding Club. For an intended channel crossing. it was towed to 10,000ft by Sqn Ldr Probyn in his Westland Widgeon G-EBRQ on 18 June 1931, but this was not high enough for the planned flight. | ||||||
