Thread:Comments:Canadian military aircraft escort airliner after bomb threat/Increase in Bomb Threats

I've noticed that bomb threats are increasing in today's society. When I was in high school, we would always have about 2-3 bomb threats every spring, supposedly by students who wanted to get out early. Though I don't know the reason for an airline bomb threat... maybe somebody wanted to get off the flight... it is rather strange why threats are increasing. Any more ideas as to why?
