Once a pax asked for the cockpit for his camcorder...I explained him that wasn't possible and he repli ed"It's not a aproblem, I know this, so I kindly ask if YOU could enter in the flightdeck, give my camcorder to one of the pilot who is not working, to film the other one while pilots during the landing"
I didn't know what to say........
with a smile "I'm sorry, but both pilots work during the landing..."
