Gulli - I wasn’t suggesting he might have run out of fuel or even got close to it, just that it might have been low enough to make a divert to somewhere with known acceptable weather difficult, so adding to pressure to land at WN. I imagine say 100kg of fuel is enough to burn a crashed aircraft well. But certainly not enough to fly much further at night. Clearly bad flight planning, but just pondering as to why a presumably highly experienced pilot got himself in this situation.
