The Boeing 737 Classic are narrow-body airliners produced by Boeing Commercial Airplanes, the second generation of the original Boeing 737-100/-200. Development began in 1979 and the first variant, the 737-300, first flew in February 1984 and entered service in December of that year. The stretched 737-400 first flew in February 1988 and entered service later that year. The shortest variant, the 737-500, first flew in June 1989 and entered service in 1990. This particular version is a 737 - 300F which is the frieghter version which JET2 operatd. Put in its shiny silver and red, this heavey haller. Here is how to operate: Use 1 and 2 to turn on engines, 3 for landing lights, 4 for cargo door (VTOL), 5 for flaps (VTOL), 6 for aileron trim (VTOL), 7 for parking brake (VTOL), 8 for gyro scope (to help keep plane level, and (g) for gear. This model particularly contains a very detailed cockpit of the 737-300 and is present in my commercial model as well. Highly realistic and places you right in the pilots seat!
