Why is it HUET for the pilot and not the passenger? ( I know the answer)
Do you want to have a 30-minute briefing before the flight, the result of which would be to scare the fork out of the customers and they will refuse to fly?
I made a 4-minute video of how the different seatbelts, door handles, sliding and hinged doors, intercoms and lifejackets wortked. All the customers were interested in was the well-constructed girl strapping into the full front-seat harness (Lift, and separate, like the old Berlei ad) and using the oral inflation tube. But I had done my bit, and if they didn't listen it was out of my hands.
