PeterTG, it could have been shot down for all we really know.
A lot of the current 'speculation' here is probably because of past history- its not the first time that this particular aircraft has fallen short of MB.
A lot of people criticise speculation. Did anyone read the thread on the Air North Braz? Remember all the comments about assy training? People thought that that was speculation as to the cause, but lo and behold it was apparently just that.
Carby ice? Yes a possibility, but I'd be surprised.
As you say Peter, "keep a close eye"... If it was indeed ice, somebody presumably wasn't paying proper attention!
Nice post 43. Just goes to show that high hours doesn't necessarily mean high incidents! Sunny might not like that though.
