I bet the private BA Pilots forum contains the answer - oh wait a minute - they haven't got one on PPRuNe anymore ...
I hate to disappoint you but even the non-Pprune union hosted private top secret Tufty club eyes only BA pilots forum has not got the answer- discussion of this incident was locked down by the mods very soon after this happened (and so as not to add to the rumours I'll mention that such action is SOP there for any high profile incident, and done for lots of good reasons).
Looks like we will have to wait a few days for credible rumours from credible sources.
