- I was, or am, under the impression that there are turbine blades on
- the wheels that do rotate them some after the undercarriage is lowered
- but it still does not get them up to landing speed. BTW, doe anyone
- know why one set of wheels on the 747 hangs at an angle? Is it some-
- thing to do with autopilot landings?
