either in flight or prior to take off is it possible to visit the flight deck?

JAMES asked: i was watching a tv Program yesterday and one person did. just wondering if you asked the pilot or crew if you could visit the flight deck whether you could do it, or are all airlines so tight on security that they rarely allow it.

i live in europe so i don’t know [...]

am visitng europe and have a transit thru London. Can i be able to visit London without a UK Visa?

colorful asked: I have my connection flight at Heathrow after 6 hrs. I dont need a transit visa to go via LHR.

How old do you have to be to fly alone?

gєmmαα (: asked: I’m 16 in March 2010. My cousin has just moved out to Australia and said to come visit when i’ve done all my GCSE’s so will be going in the summer. Would i be able to fly on my own?
I’m from the UK so will be about a 22 hr flight?
Thankyou.
