Take a flying lesson. For most, fear of flying is a lack of control issue, and taking control of a plane helps it greatly. You can get an introductory lesson at almost any small airport for around $100. I learned to fly from a lady who took her first lesson that way, on the recommendation of a therapist. She ended up an aerobatic instructor!
