When I was about 10 or 11 I used to believe that the mile high club was a group of powerful business men in suits who would fly around the world on a huge fancy private jet, staying up for days at a time, drinking and smoking cigars and discussing their plans to manipulate markets, politics and wars for their own gain. I was disappointed when I found out it was just about sex, my version seemed much cooler.
