When Trans Canada Flight 810-9 Was on Fire, Losing Altitude and Lost Over the Cascade Mountains

The plane at the center of this episode of Radar Contact Lost was in a bad way: One engine was on fire – there were three others, but the plane was struggling to maintain altitude. In addition to the engine fire, it was experiencing turbulence and severe icing, it was crossing the mountains at night, and in the middle of winter storm. As if that wasn’t enough, the plane was also lost. It appears the crew didn’t realize they were lost, but they were well off-course, just the same. 

This alarming situation was taking place over western Canada in a 4-engine propeller airliner in the middle 1950s. The plane had no empty seats. The passengers were likely unaware of the dire situation, though many had likely seen the engine fire and were aware that one engine was not working. 

In this episode, we’ll talk about the plane and the mountain that the plane crashed into. We'll also talk about the memorial to the victims of Trans Canada Flight 810-9 and what it was like to be a passenger on a commercial airliner in the 1950s.

I'll also share the meaning behind a weather term that I’ve noticed a lot of television weather forecasters use – and that they use it many times without an explanation – or at least without much of an explanation. The term is, “the atmosphere is capped,” or “the atmosphere is uncapped.” I’ll explain what a capped or uncapped atmosphere is all about.
