However, there are problems. When you spin a tire it acts as a gyroscope and will resists having it's course altered. This can make handling tricky as you would have 10 or more wheels all spinning on most airliners. Have you ever held a spinning bicycle tire in your hands and tried to move it? Same effect. You also need to weigh the advantages against the disadvantages. How much does the tire wear cost the airline? How much would mantenance on a system to spin the wheels cost? Plus you will have the initial cost for the system and the added weight. It is one more system to break down, etc... All in all it just doesn't appear to be worth it... ############################################################################### # I have one prejudice, and that is against stupidity.
