If you are correct that agaricus' point was that the Chinook Mk 2 was, at that time, un-airworthy, then I apologise. He was absolutely right.
DOUBLE BOGEY
We really shouldn't digress, so all I will say on the matter of the Mull is this. If you were discussing issues of fact, we could have a debate. However due to the lack of any survivors, any eyewitnesses, or recorded data, we are left only with matters of opinion. Yours appears different to mine, but then I am probably as familiar with that accident as it is possible for anyone to be. After a long fight by many of us for justice, my opinion is now in accordance with the official view. Yours is not, but of course if you too have the courage of your convictions, you could always now do as many of us did, and embark on a 17 year fight. Rather than simply bumping your gums together.
Apologies for the digression, but the link (if there is one) is the value of data/voice recording in accidents. It provides a window to the truth. Rather than allowing 'opinions' to prevail.
