What I find instructive in the explanations of the video is the fact that a drone does not hold up with wind, and that it would have destroyed itself under conditions where the kytoon operated.
This ties in with the AWE drone crashes which have been reported, even in a different context, AWES being tethered unlike the drone described on the video.
I do not see how a tethered drone could produce MW reliably and over time regardless of the conditions, whether it is a quadcopter or a plane or both for VTOL operations.
We can therefore deduce from all this a poor future for AWE drones whatever they are, unless spectacular progress related to control.
It is perhaps not for nothing that we do not see a tethered drone when the power kites are legion.
The lesson to be learned is that AWES should limit themselves to what already flies well.
