Gerhard, You are a quick thinker. I'm not sure if I could have reacted so calmly under the same circumstances. As a frequent business traveler, I really appreciate your candid expression of how this happened and your thoughtful advice should this happen to the reader. Right now I'm very keenly aware of doing my own 'profiling' when watching fellow passengers board an airplane, but in future I'm also going to be more mindful of my surroundings when traveling on the street. Best regards for your future safety and for all of us road warriors. Willis
