De Havilland Canada EO-5 Dash 7
The de Havilland Canada Dash 7 was built around exceptional short-field and quiet-operation performance. Its four turboprops, large flaps, and propeller reversing capability allowed it to use city-centre airports with steep approaches, including London City after certification trials. The aircraft was quieter than contemporary regional aircraft, a major selling point when airport noise restrictions were tightening. Although it was later eclipsed by faster twins, its STOL performance remains extraordinary for a 50-seat airliner.

The US Army's EO-5C variant used the Dash 7's quiet STOL performance for airborne signals-intelligence reconnaissance rather than passenger service.
