In the second flight, the downlink signal ( ie, video feed and telemetry data ) started breaking up when the drone was 1900 ft away from the home point indicating that there was either interference or there were some problem with the radio on the controller / drone side.
any ideas on what happens?
Does drone go straight down? Would it veer left or right? Could it continue flying till battery ran out?
Anyway, RTH has already started before the black out and there was a mild tail wind so the drone should have returned to the home point automatically after 1.6 minutes unless something happened on the way.
