My fear of shop assistants is as nothing to my fear of flying, which, if I'm being honest, is actually more a fear of turbulence. Now a Texas-based travel company has come up with an idea that may help me overcome my aerophobia. It is offering nude flights to naturist resorts in Mexico. The experience will be utterly embarrassing, of course, especially when queuing up for the loos. But at least when you encounter turbulence you will be too distracted by the sight of wobbling glands and jiggling appendages to feel scared.
