Such a scenario is consistent with the final BFO values that correspond to ~4500 ft/min descent rate at 00:19:29 and 15,000 ft/min at 00:19:37.
FWIW, the
acceleration in the descent rate between :29 and :37 averages out to ~22 ft/sec/sec, close enough to 1g (~32 ft/sec/sec) to suggest near free-fall.
However, take the calculation with a grain of salt:
Besides, according to Inmarsat engineers in the Journal of Navigation "it is prudent to discount the measurements between 18:25:34 and 18:28:15 inclusive, and the one at 00:19:37."
