“[ The actual veer-off/failure occurred in space during a separation event, seen at 2:19:50 of the video in question-Best Regards, OGINJ ]”
Second stage shutdown early. Nothing to really see.
The onboard camera tells the tale of the veeroff from the rocket’s perspective.
But yeah, nothing to see in terms of video shot from the surface of the earth or from a tailing aircraft.
The failure was due to the premature second stage shut off which prevented the satellites from reaching their intended orbital velocity. Someone may have failed to load the necessary fuel or there was a second stage failure of some kind. Strange it would occur at the last minutes of the launch.
