this is an interesting topic. before 9/11 i loved flying....now, hate it. will not do it unless absolutely necessary, unless in a friend's airplane. i wonder though....even without 9/11...would we have "upgraded" our airport security eventually? it was very lax. i speak only to airport security. i think it would have had to upgraded with or without 9/11. without 9/11 i don't think we would have the fear of shampoo and water or whatever it is they don't let you bring aboard planes ( i have not flown since 2002, though i will for the hawaii trip this year)
