Bottom line is, they're about to throw the book at him.
Seems like there are plenty of lessons to be learned (or relearned) by many individuals and organisations. It would be unfortunate if he's the only one to be hit by said book - and that's assuming it's warranted given that the investigation isn't over yet.
The CAA letter in the Times certainly comes across like a pre-emptive shot based on early access to the report, BWTFDIK. On the other hand, the response by BADA came across as a little pompous in tone (I'm surprised that FL thought it was OK) and some of retorts (e.g. a system admired throughout Europe) are difficult to reconcile with the AAIB update.
Widger, a diverse board background makes sense for a publicly listed company like BA with the usual suspects of Chairman, CEO, COO, CFO, CIO, etc. I'd have thought that the CAA would have a board with more flight related experience, wouldn't you?
