We shot a CAT II and landed right in front of him. Heard the whole thing happen. He sounded like a Chinese student of some sort. He burned up all of his gas doing multiple approaches into FRG. Couldn't hold the localizer. His second to last approach was all over the place. He ended up way left of course, turned back to the runway, tried to line up for 31R, which is closed, and then went missed, came back and ran out of gas on his last ILS.
I don't think he or the controllers understood the severity of what was going on until it was too late. He didn't declare an emergency, ATC did, and they tried to get him into JFK. Once they realized how grave it was, they did a great job of trying to get him on the ground, but it was a bit windy and 1/8 mi visibility. We heard his last transmission. "Out of gas". We thought he died. It was pretty crazy.
