While the MiG 29 pilots are stealing the air display with their breathtaking tail slide – the aircraft makes a vertical climb to 3,000 feet and just stops until gravity takes over, whereupon it pulls out at about 1,500 feet – and the giant Antonov 124 transport made a spectacular bang when its number two engine flamed out on Sunday – there is plenty of computer-related interest at this year’s Farnborough International Air Show, which has its final fling on Sunday: British Telecom is focussing on its embryonic ground – to – satellite – to – aircraft telephone systems and a complementary ground-to-air one; GEC Marconi is talking about its Macrospeak speech recognition system; Wicat Systems is celebrating a whole string of computer-based training system contracts in the aerospace world; and Hunting Engineering Ltd is showing off a Mission Planning System that puts up some pretty sexy maps on an Apollo Domain 4000 workstation, and was due to meet the managing director of its parent’s latest acquisition, Lynwood Scientific Ltd, to discuss what they can do for each other.
