Zeke, no doubt the FDR is the most important piece... Until that gets released, we can only go ny the ADS
And as far as I'm concerned, even if this is accurate, we still need the FDR... of course

It's just a timeline of altitude, based on the data reported by Mandala499, not accounting for groundspeed or distance..
Nicely put... please add:
23:18:45 24025 (last valid with Baro Alt of FL235)
Impact is between 23:20:16 to 23:20:26, this was at the press conference somewhere... but I can't remember the exact time... it is between those two numbers.
You'd see that the final fall is roughly straight from at 23:19:03 / 34125 ft.
If you then look at the average vertical speeds between the points, then the vertical speeds become less spectacular and make more sense.
23:16:33 34000 -
23:16:52 33975 (79)
23:17:29 37075 5,027
23:17:43 38850 7,607
23:18:03 34125 (14,175)
23:18:45 24025 (14,429)
23:20:20 0 (15,174)
These numbers would not be too far off the numbers we saw in AF447... conveniently... *pretty numbers syndrome caution! consider with extreme caution!*
Elapsed Time 0:04:22 0:03:28
Time To Peak 0:01:04 0:00:51
Climb to peak 30.5 48.75 (FL)
Average Clb 2,859 5,735
Peak to Fall 379 367 (FL)
Fall Time 0:03:18 0:02:37
Average Fall 11,485 14,025
Given that QZ8501 was well below it's optimum altitude of FL380 and that AF447 was near it's optimum altitude at FL350... The difference in the climb and descent rates are not spectacular whatsoever in my opinion.
