Jayteeto,
Your post #2424,
"The crew ate choccie bars while they went through FADEC emergency drills in the crewroom"
I'm impressed that anyone could be eating "choccie bars" so soon after eating a "Full English Breakfast" in the Sgt's Mess - who, as you are doubtless aware, get larger portions than either the Officers or the Airmen!!
You do not, however, address the more important point: why did Tapper go to Met alone? HQSTC ASI's - ALL flight deck crew, other than Air Eng, go to Met Briefing - period!!
I must confess, however, that recent posts seem to reveal that a large portion of Aircrew Operating from Aldergrove seem to be totally unaware that the Airfield had a "Met Office". In the 25+ years that I operated into & out of that Airfield I never once failed to find it!!
PS Those 25+ years were ALL in the period of "Civil Unrest".
