Okay, okay, okay...

Apparently I didn't make myself clear enough. When I said the aircraft has to
reach flying speed, I was oversimplifying. V1 is indeed the speed at which the
aircraft is assumed to no longer have enough runway remaining to stop safely.
Many (if not most) takeoff accidents are from pilots trying to abort a takeoff
->after reaching V1<-, thereby proving once again that F=MA.
Vr is the speed at which the pilot is required to lift the nose and the
engineers say the plane SHALL fly off the runway.
V2 is the minimum safe flying speed.
