I wonder if it is even possible to go much faster? sound barrier is only 200 miles an hour faster...

The theory is (and it seems to be holding true) that the speed attainable is about 1/10th the wind speed....

Should that be the other way round? With a 50 mph wind you get 500 mph? So wind speed is 1/10 the airspeed? So on an 80 mph day you could do the speed of sound! Can you imagine a sonic boom from a glider, that is something I'd like to witness.
