Well according to the AAIU spokesperson on the six one news last night, a prelim report will be issued within 30 days.They certainly have no shortage of evidence to this accident. Between the CVR, CCTV, eye witness accounts and pilot account, we will get a difintive answer I would think. Hard to know if it was landing or taking off from the CCTV footage on Sky, but it does look to be in a relatively steady hover before it all goes horribly wrong.
