I've been thinking about White's anxiety disorder and what can be done about it if anything. Surely steps to resolve it or mitigate worst forms affecting him can and should be taken.
Flying on a commercial airliner is the most safe form of transportation on planet earth. You are thousands of times, even millions times more likely to be killed driving to the airport to board the aircraft than killed in plane crash. For years as a youngster I had certain fear of heights. I recall once standing on the rim of the Grand Canyon and looking down. Fear suddenly consumed me and while others edged closer to get better look I wanted to stay well back. I was around 10 years old at the time. It was only phobia (acrophobia) I ever really had. But after a few plane rides by my teen years the anxiety seemed to fade into history. Since that time I've taken hundreds of flights all over the world and a fear of heights issue or flying paranoia is now completely gone, like I never really had such "silly problem." For me, it was about growing older, maturing, learning, and slowly letting go of such fear - at least in its most debilitating form.
