If the article in the current edition if "The Log" is to believed, this aircraft is only for the MOST experienced pilots. Those without this experience won't be able cope. Also, because of the large number of cabin crew, "a clear lead has to be set" by the commander. ...and other such tosh! Or there again, you could take the Qantas F/O's line, another contributor to the same article, that this is just another big aircraft.
However, what I did get from the article was a "whiff of Walpole" therefore I'll not fly on one BA's in case I get the clown who wrote the article. The odds are not good enough.
