I did an Eastbound trans-Atlantic flight one night on a Laker DC10. (June 1997)
"Freddie Laker jnr" was on board and he made his own passenger service announcement (is that allowed??) that he would be travelling back to London with us - and would be touring the cabin to greet each individual passenger, personally.
He brought with him a cameraman, who was operating a full size Sony (television news style) shoulder held camera - with a huge light on top - and a radio microphone clipped to his shirt collar.
Two sets of rules, I suppose.
