Where do you get all this information from?
Readily available, Gordon Vette "Impact Erebus" has some good photo's taken just before the crash, Hempys post with the photograph of the crash site, the impact point was near as dammit 1,500ft, which they had to go down to to get under cloud.
Not again, still. If people cannot do a bit of research before coming up with inane comments, will probably be going for years yet.
