Hello again. I remember one flight on a 737 where we were delayed for an hour on the apron. A couple opposite me decided to get a bag out of the overhead locker. The aircraft hadn't moved but they managed to swing their own bag down out of the locker and hit someone in the head with it. Fortunately, they'd disturbed another bag which hit one of the couple on the head and they all sat down to reflect on gravity. I've seen similar happenings on the more humble trains here in the UK. Gravity and inertia usually win. Regards, Rog.

Actually, it usually starts with an idiot who can't get his facts straight: "It should come as no surprise, as Rasmussen Reports said Tuesday, that the recent government bailouts of General Motors and the Chrysler Corporation have affected public attitudes toward the U.S. automakers. But rather than pitch in to help the struggling manufacturers continue to stay afloat, 46 percent of Americans indicated to Rasmussen that they were more likely to buy a new car from Ford-if they were, in fact, buying a new car-because it did not take government money in order to keep its doors open. Call it a competitive advantage for Ford. By staying away from the bailout, the company has potentially increased its share of the market place by a significant amount, especially among those who insist on "buying America" as a political statement." http://www.usnews.com/blogs/peter-roff/2009/07/28/fords-auto-bailout-lesson-consumers-like-rugged-corporate-individualism.html If you ever hope to be taken with even a minute amount of credibility, pay attention to what's going on around you... Take Care, Dudley
