Once stabilised, there is no 'acceleration', and one does not feel velocity, but one can hear it. There were no CUES, the STALL was abnormal. They felt more or less as they would have felt on the ramp. There were fluctuations in VS, and these would have added to the confusion, imho. Accelerating from the top of climb would have likely been exhilarating, but reaching 100 knots down in vertical velocity would not take long. The ship showed manageable, if not pleasant characteristics (in the descent, STALLED), again a confusion in territory one has been led to believe is mysterious, and unavailable to the BUS.
When stable at 1g, the Vertical speed would not be believable, it would be hard to accept. Close to the surface, the pilots comments were limited to specific altitudes, not their vertical speed. Again, they had no instrumentation or feel that suggested their predicament. No "believable instrumentation", that is. So get a grip, and lose the feigned shock; in that cockpit, no one would know what was happening. Acting like these three were too thick to sense the obvious is ridiculous. Nothing was 'obvious' and I feel no flyer would have had a clue.
What mystifies me is the power they carried throughout. If too fast, and in some kind of descent, closing the levers would be second nature. Is there a remote possibility They were in Autothrottle? Could they have been in Autopilot? At any time after the first loss of it?
Have BEA rejected with proof that the climb was uncommanded, or partially so?
