This is good news, but I have to wonder how they, or we in the US would
protect the cable from other aircraft that might stray into it at those
altitudes. Next question is how far the cable would drift on the way
down, assuming that the wind is not always right down the runway.

Good show!

Dyneema/Spectra winch cable allows for launches to approximately 50% of the
original cable length. Calculations show that there is really no upper
limit to the amount of Dyneema that can be used.

90 seconds to 5200 feet AGL on a winch beats the hell out of 20 minutes on
aero tow. That's especially true when the typical cost is $10 for the
launch.
