What do people think about this 1. Put steam catapults on all airport runways (or perhaps use Linear Induction Motors) 2. Get the plane to accelerate all the way from the gate following a track, through to launch, so acceleration for take off starts from 'go'. Apply an acceleration profile such that passengers don't feel too much discomfort but runway length is still reduced considerably 3. Get runway to rotate to take advantage of wind assistance. Doing this will (qualitative assessment) - reduce airport space required - save on fuel for aircraft - already mature technology in aircraft carriers - airport land tax costs reduced etc.... - less noise?? to name a few benefits.
