I was attending sim training at CAE/DFW and had time for a round of golf at the course just South of the airport. As a single, I was paired with 3 normal everyday non-aviation people who were also visiting from out of town. I really got a kick out of watching their reaction every time a jet flew right over us to land. First, how fascinated they were seeing airliners fly 300' right over their heads, but even more so when the vortices settled. They kept looking around wondering where that whooshing noise was coming from! After about the tenth time, I just had to let them in on it...
