Kill me for starting with
Bloomberg numbers supposedly backed up by:
Expert 1: "Scott Dunham, a former National Transportation Safety Board investigator, who combined the distance the plane traveled horizontally and vertically to arrive at a speed estimate." {600mph}
Expert 2: "John Hansman, a Massachusetts Institute of Technology aeronautics and astronautics professor, estimated the plane was flying at 540mph in the final moments..."
Expert 3: Jasenka Rakas, a lecturer in engineering and aviation at the University of California at Berkeley "...the speed could have been between 586 and 633 mph."
added Bloomberg hype? "At the end, it fell 1,025ft in 1.6 seconds."
I thought the ~600mph was vector sum of vertical and horizontal velocities.
Flightradar24 data looking at timestamps,
it was at 28,000ft and took minutes to drop, so -33,000ft/min seems wrong too. 2018-10-28 23:31:56Z.030 last two samples do say it fell 1,025ft in 1.6 seconds.
edit: confused flight JT610 with JT43.
