checkboard, how wrong could you possibly be??!!
these days it's not just the drunken, 120 kg footy player on tour that "gets physical" with us. in a previous 'service' lifetime, i personally saw a 40 kg woman take down a large male employee by wrapping his own tie around his neck and dragging him to the floor!
mate, if your an fa, think a bit more laterally, and if your tech crew just stay behind your locked flight deck door and i'll bring you a coffee later - physical well- being permitting!
