Killjoy time. The rules in the UK do not permit all of what is suggested. The definition of crew and flight crew is in CAP 393:
‘Crew’ means a member of the flight crew, a person carried on the flight deck who is
appointed by the operator of the aircraft to give or to supervise the training,
experience, practice and periodical tests required in respect of the flight crew under
article 42(3) or a member of the cabin crew;
‘Flight crew’ in relation to an aircraft means those members of the crew of the aircraft
who respectively undertake to act as pilot, flight navigator, flight engineer and flight
radiotelephony operator of the aircraft;
For sure camera persons are not classed as crew or flight crew. Happy to be corrected - because in the wording quoted above I can see some hope. But am assured by Gatwick that they do not regard camera persons as either flight or cabin crew.
