on this day in 1997.
The British Sub-Aqua Club (BSAC) was founded by Oscar Gugen, Peter Small, Mary Small, and Trevor Hampton on this day in 1953. The club peaked in the mid 1990s at over 50,000 members declining to over 30,000 in 2009. It is a diver training organization that operates through its associated network of around 1100 local, independent diving clubs and around 400 diving schools worldwide.
Supersonic land speed record
The car was driven by Royal Air Force fighter pilot Wing Commander Andy Green in the Black Rock Desert in Nevada, United States. It was powered by two afterburning Rolls-Royce Spey turbofan engines, as used in the British version of the F-4 Phantom II jet fighter. The car was 16.5 m (54 ft) long, 3.7 m (12 ft) wide and weighed 10.5 tons (10.7 t), and the twin engines developed a net thrust of 223 kN (50,000 lbf), a power output of 110,000 bhp (82MW),burning around 18 litres per second (4.0 Imperial gallons/s or 4.8 US gallons/s). Transformed into the usual terms for car mileages based on its maximum speed, the fuel consumption was about 5,500 l/100 km or 0.04 mpg U.S.
