Actually for those that still try to keep bringing up this extra momentum or kinetic energy rubbish ask yourself why a glider doing a low, high ground-speed, downwind pass over the strip can't pull up any higher than a glider performing a the same pass into the wind at the same airspeed (but lower ground speed)????

In both cases kinetic energy will be converted to gravitational potential energy, but the final GPE in both cases will be the same, even though the glider doing the downind pass has a much higher ground speed....
