Cazatou,
Long time no hear.
Rather than enter yet again the argument about whether the weather was suitable and legal for this flight, I suggest interested parties go back to this thread in mid May this year. There are many entries on the subject.
The basic jist is the weather "forecast" was suitable for the low level transit around the Mull and up the Great Glen.
The "forecast" did rule out "safe overflight" of the Mull due to the icing limitations of the aircraft.
No one knows the "actual" weather conditions encountered by the crew.
Now unless you have any new evidence, I thought this subject was dead.
