As a youth, the de Havilland Canada Dash 7 was, if not a widespread aircraft, one that was reasonably popular. This was a time when STOL operation was such a big deal with the idea that STOL aircraft would make operations from cities more of a thing. This idea didn’t last long but, at the time, a four engined aircraft with the ability to guarantee climb out in an engine out condition was important which also is why the 146 was a four engined plane.

As the focus shifted to regular airports, twin engined turboprops took over including the same company’s Dash 8. The Dash 7 has hung around in niche uses but they are not easy to find. Air Tindi operates them in Canada and one of their airframes showed up in Seattle a while back. Magnix is a company that is making electric powerplants for aircraft and it is supposedly using a Dash 7 as a testbed. It showed up at Boeing Field for a publicity event. Sadly, I didn’t see it in flight, but it was out on the ramp at the FBO for a while before it was moved into the hangar for the event.
