safety briefs
Most graphic safety brief I've had was from a London HEMS pilot who jumped up and pulled the blade down to neck height.
I never forgot that and so always remain in the cabin after landing until the blades have stopped, even in a jet banger, which is occasionally embarrassing when the pilot walks off under the spinning main rotor.
I jump in and out of numerous helicopters, I'd rate most safety briefs 7/10 as they just do go far enough in driving home the point that the rotors can flap down to below head height.
I learnt something the other day which was to check that the seat buckle is right way up, because if it isn't your body weight will make it impossible to reach and undo in a roll over.
Full marks to those pilots on week long filming jobs who begin every day with a safety brief.
