Once again this is conjecture and I'm not sure the video is even taken onboard VINSON however the power (perhaps to burner because I hear a HOWL at last second) comes on 'at the ramp' but all my conjecture could mean a fairly ordinary F-35C carrier approach. LSOs by the many monitor these approaches so any pilot not responding to their calls will be in big trouble. Anyhooo....
