The record attempt over a distance of 656 feet (200 metres) on a runway at Elvington Airfield in Yorkshire was monitored by independent adjudicators and timekeepers.

Flying Dutchman Fred Rompelberg was the previous record holder, reaching 166.9 mph (268.831 km per hour) in 1995.

Campbell, an architect by day, is no stranger to setting records - he broke his own European motor-paced record last year, clocking a speed of 149 mph (239.8 km per hour).
