Boeing 737-400
The Boeing 737-400 is a stretched version of the 737 Classic family, extending the -300's fuselage for extra passenger capacity on the same wing and engines. Its longer tail required a small tail-skid to protect against striking the runway during a steep takeoff rotation, a feature not needed on the shorter -300. It became a popular choice for airlines wanting more seats without moving up to a larger, more expensive aircraft type. Many remained in active passenger and cargo service for decades after production ended.
