AlexB....actually you can still buy logbooks onboard for a £1 and the crew will happily pass it up to the flight deck to be signed...unfortunately you wont be able to accompany it up there unless the plane is parked at a stand!!!
Nooooooo! its just not as fun is it?
I remember ~'96 when my cousin was killed in a motorbike accident in portugal, on the flight back home the captain invited me to sit in the jumpseat for the last 40 mins of flight, i nearly wet myself with excitement
I wore a headset on approach, activated the rain repellent switch,and the FO spent 15 mins telling me that I should become and airline pilot because the BA pension was excellent.
Ahhhh memories!
