Boeing 737-300 is commencing its approach seconds after a cumulonimbus-cloud drifted over the airport. The Boeing 737 was launched as a short-range airplane in 1965 to complement the larger 707 and 727 jetliners.  Engineers chose wing-mounted engines for the 737 instead of an aft-mounted position like on the Boeing 727,  Douglas DC-9 and BAC One-Eleven. The 737 configuration includes a 707-width body, a significant reduction in overall fuselage length compared to the 727 and less structural weight per passenger carried.
