It's probably no surprise that I knew the story a long time ago.Holy shit! I was just looking at my Flightradar24 app, and I saw a plane coming from the Toronto Airport, which has airport code YYZ. This is the basis for the Rush song of the same name. In fact, the morse code for YYZ is used as the opening rhythm of the song. I never knew this.
I may have known before they taught IRBS in grade school.
