When the jets fly at low-level they in Labrador, they are practicing flying bombing missions, flying so low as to avoid detection by radar. They are flying fast close to the speed of sound which creates a loud roar and there is very little if no warning before the jet is above. You often don’t see it or hear it before it arrives. For those in canoes and those in the quiet of the wilderness, this can be frightening and potentially dangerous. While in Labrador, we heard stories of jets returning to the airport with spruce sprigs caught in their wings. Whether or not it is true, it does indicate a culture of getting as low as a pilot can.
