My thanks to those of you that have replied so far. As I am grateful for the constructive comments made apart from the second entry that is !!! Only joking LOL.
And no it's not a wind up question, for before 11/09/2001 you would often read about people's J/S experiences and good reading they made too.
It's interesting and indeed good to see that the occasional crew is able and willing. After all, how many of us were inspired by that first time to the Deck. However, I do of course respect the issue of security and to be fair, if I was a passenger and saw someone not in uniform going up to the F/D, I might just start asking questions.
Cheers to everyone.
