Easy to laugh
I find it interesting that there is so much chat about the obvious. Poor airmanship and frankly an embarrassing moment for our profession. However I would venture a guess that these pilots where Toronto based and running on the back of the clock after a long day. AC was also involved in an incident of falling asleep at the controls only to wake up and violently manoeuvreing to avoid hitting a star. When will we band together and force laws to protect the flying public from tired pilots who are making life threatening decisions.
