Sorry to say, but I have to support the ban. Speaking with your head twisted around for so long to people when you are travelling at up to 600mph with up to 400 people with you is not such a good idea. I have had people wanting to 'bring their son up for a look' and appear with a babe in arms, and with a full nappy at that, I have had people up who you suddenly realise are inebriated, or just bored. We once had several visitors on the flight deck with both us pilots twisted around talking when I heard a very soft sound. Took a few seconds in all the talking to identify the noise as like a 747 engine surge. I turned around to see the exhaust gas temperature quietly winding up and closed the thrust lever and had to shut it down.
Now if only someone up there was actually listening to the radio instead of watching the guages ......
Today was the worst day ever in my career of having to say things twice (or more), or getting airline ops to get plonkers on ACARS, or company relays to come and join everyone else on the
operational frequency, etc, etc, etc.
Closing speeds of up to 1200 Mph and some still want to look at that cheese board
