As this drama unfolds I have to "defend" to several not-flying friends, that these situations can and do happen. Very rightfully they ask how in the world a crew can be so neglectful of their fuel state. That is so basic to them they cannot understand how a professional crew gets themselves in such a bad position with a full load of pax.
My ole company is on the verge of even more fine tuning the reserve fuel qty. Hope this accident makes them think another time.
One idea about the steep descent could be failing instruments, that made them dash for VMC conditions below clouds. Just an idea, not more.
Yes and for the ATC lady: my (worn) hat off.
