44217 Whittle           Discovered 1998 Aug. 12 by J. Broughton at Reedy Creek.
British aeronautical engineer and pilot Frank Whittle (1907-1996) was the inventor of the turbo-jet engine, which he first patented in 1930. Such an ingenious yet simple method of high-speed propulsion made flight an affordable and relatively safe form of travel for the masses.
