N703SW is see here with the rare Pratt & Whitney JT9D-70A engines. With 53,000 lbs. of thrust, it was the most powerful jet engine in the world at the time of its introduction into commercial service. It first appeared on 703's sister-ship, N702SW, in May 1976. N702SW was the test-bed aircraft used for certification of these engines. It was developed with the 200F freighter in mind, and is instantly recognizable by it sleek profile and elliptical cowling.
