Has the airplane done the human race more harm than good?

It is definitely a plus the aeroplane was invented for travel and for goods to get from one place to another. They say its safer to travel in a plane than drive but I personally do not want to trust my life to someone 30,000 feet in the air who may or may not be sober and in a good mood. Then too you got the hijack and terrorist thing. Many people enjoy flying and could not live without it..
