So I'm close enough to the flight path into/out of YQB that I can usually hear any departing or arriving planes - so when I heard a jet at around 12:15 am I checked out my FR24 app, thinking it was TS' LGW flight taking off. Lo and behold, I found that it was actually the YYZ-FCO flight, which had diverted somewhere over the Gaspé peninsula and was landing at YQB. On the ground for a little over an hour, and finally departed at 1:42 am, arriving in FCO at 2:50 pm local time. Anyone have any info on what happened?
