Whilst surfing another aviation forum I came across this link:
http://streaming.scmp.com/aircrash/C...ne_crash1f.avi
Which apparently has only just been released and shows the horrific last moments of the MD-11 which crashed in a typhoon at Hong Kong in August 1999.
As a relative layman what amazed me about this video is that the final stages of the approach did not look unduly out of the ordinary. Yes there was a small amount of bufetting but compared to some footage I have seen (various Kai Tak, 321 at Lisbon) the aircraft looked under control. I cannot fathom what actually caused such a catastrophic end?
