The de Havilland Canada DHC-7, more commonly known as the Dash 7, is a remarkable airplane when it comes to STOL (Short Take Off and Landing) capabilities. It was first made in 1975 and the last airplane came out of production in 1988. The oversized propellers, rotating slower than other aircrafts, made it a relatively quiet propeller airplane. In many aspects, the Dash 7 was a larger version of the two engined Twin Otter. The main differences was size, two more engines and a pressurized cabin. The four engines provided extra lift at low speeds, due to two engines on each wing, with propellers blowing air over the whole span of the wing. At landing, when put into reverse, the same propellers slowed the airplane down quickly.
