I did wonder if it was visible to other people/drone users, just in case any other drones were up there in stealth mode. Half expected you to get a wave from the people in the car park at 11m35s.
Due to other LEDs on it, as well as the strobe I use at night, it probably looks like a UFO if you don't know what it is - if its still, it could look like a more distant plane, but as its near, around 50-100m from the ground, it looks like its moving way too fast
That particular one doesn't have ADS-B (a common system used to monitor aircraft, I believe soon to be mandatory for manned aircraft in the EU/UK), but some of my bigger ones have an ADS-B receiver, so I get to see where nearby manned aircraft are
. Although the CAA rules make it unlikely that any aircraft in the sky, manned or otherwise, would get close to other aircraft... ...not that the idiots flying out of Hinton in the Hedges airstrip obey any rules.
