Be assured, wherever they got them from, and my recollection is that they came from in-flight records, the authorities presented two large graphic demonstrations on easels, one in azimuth and one in altitude.
The trace in azimuth showed the aircraft wander in an irregular track as the crew met and pretty much overcame each successive problem in a series: the first engine cut out from starvation; the second from indvertent feathering; loss of airspeed; probable hand-over from the first officer to the captain; and so on. The vertical trace showed gradual fairly regular loss of altitude and at the end a sudden drop into a near-vertical fall.
As is mandatory in such events, the crash in the one open small space was attributed by press and others to heroic if not superhuman efforts by the crew to avoid a school, I think it was, and put a large disabled out-of-control commercial aircraft down on a handkerchief.
