Rainboe,
no offence but your posts are really going downhill me 'ole mucker. Before I took them with a pinch of salt and even laughed and joined in so that we could wind up the original poster or who ever contradicted the main opinion - the thread on a BA747 blocking the taxiway "on purpose" in J'berg was a good example.
But you seem to be awfully grumpy of late. I loved cockpit visits as a child and it further affirmed, at such a young age, that I wanted to be a pilot and I am sure this is true for many of our colleagues. I also enjoyed (albeit for a short period before 9/11) having passengers come to the cockpit. Once in cruise, there is always time to speak with visitors - remember, you make the decision first whether it is an appropriate time to accept visitors. And once they arrive, you could politely say that if you stop talking or don't answer anything immediately, don't think we are ignoring you.
I would love cockpit visits to return - If only to look at the the yummy mummies. Flash them a smile, give them a wink, make a few innuendoes about thrust. You get the picture.
