If I was a passenger on a plane and saw fighters escorting us, it would not give me a good feeling.
I know he is not there to protect our plane from enemy fighters. His only purpose as far as I know would be to shoot our plane down rather than have it crashed into a target.
Just to orient you a little (no pun intended), plane was probably somewhere near southern end of Alaska panhandle when diverted back towards Vancouver, it was in the air almost three hours so if you assume 1.7 hours out, 1.2 hours back, it was likely closer to Ketchikan or Prince Rupert than where it landed at Comox. That choice may have been for safety given the combination of weather and airport layouts, proximity to military base (near Comox) and possibly thinking of potential need to bring in a second airplane later. Have not heard any details on local news about what actually happened beyond what is generally known from these reports. In any case, this must have come to the attention of the crew at least an hour and possibly closer to two hours into the flight otherwise they would have landed a lot earlier at Comox or gone back to YVR.
