Re: "Virgin Galactic has remained tight-lipped over what happened"
Not so. They publicly explained that a slightly prolonged spell at an altitude with higher-than-forecast winds blew them a little off course. They also noted that such events are common enough in regular commercial aviation.
The problem was that it blew them off course far enough to make it a real concern that they had the range to glide back to a proper landing. And normal aviation doesn't have to worry about that sort of thing.
