GJB,
I've jusr re-read both the AD and the Private Eye article posted earlier. Both mention "a recent crew incapacitation incident in the UK". To me that tends to lend credence to the PE report - let's hope they've got their research right. If they have, they need thanks for placing a matter of great importance into the public domain.
As for getting AAIB reports from the newsagent. Well I don't know how many my local stocks but I'll ask tomorrow.
