I say moon-less night (July 2 was the new moon) and black hole departure transitioning from over land to over water either lead to the demise of the flight (spatial disorientation) or contributed very significantly with zero time and zero visual reference to save a mechanically impaired craft. Happens all the time down here even with most experienced pilots. That night was one of the darkest of the moon cycle. It was a very dark night. I flew that night in South Florida.
