Police helicopter crashes onto Glasgow pub

[Munnyspinner]

Can we dispel the freefall from 1000'? An object weighing say 2450kg falling from 1000' would take around 8 seconds and arrive at 0' at a speed of approximately 80m/s that's around 290km/hour or 180mph. We know the aircraft was in normal flight at around 700' shortly before the impact. It was heading west but ended up to the north of track heading north with no apparent horizontal velocity. Prior to the fall, there was an as yet unexplained sequence of events resulting in apparent loss of power and, at some stage, Nr becoming zero. There is no reported evidence of a major catastrophic mechanical failure. The engines were reported as being capable of delivering power, although it is not reported that they were producing power, and both the maingearbox and TRGB were recorded as being intact and capable of functioning normally prior to impact. I am not quoting the AAIB report verbatim but I believe that these are the general facts. Around 95l of fuel was drained from the aircraft after extraction but it us not clear from which tank(s). A low fuel warning erroneous or accurate in isolation seems unlikely to have precipitated events. However, the absence of a low fuel warning and flame out on one engine may have been the first in a series if events.
