@Dave Reid and Scifi - you guys will have to get together and get your stories straight. Wheels are spinning after takeoff for, what, 10-15 seconds? "Positive rate!" - "GEAR UP!" And often immediately braked while still retracting. Decelerating.

Scifi expects them to spin up on gear deployment, 90 seconds (on average) before touchdown. And during the phase of flight where one is trying to nail a target 3 feet wide (the centerline). And where braking defeats the whole idea - they are accelerating to match landing speed.
