One of my flying experiences was in a helicopter, one of those 'joy ride' affairs at steam rallies.
Myself and three others from our Land Rover club decided to go in the helicopter. We paid and headed over to the nearside door and got in, I was last.
Every one grabbed their lap belts but the bugger who got in first grabbed the wrong pair of straps and so by the time I got the door shut and started looking for my belt I only had one side of it, the side closest to the door.
Despite my protests the pilot took off and started circling left banking right over so everyone could look out the window at the ground.
I had three blokes leaning against me pinning me to the door. I had my left hand wrapped tightly around the single lap belt strap and my right hand in a vice grip around the angle iron strut under the seat.
Then the door clicked open one notch on the latch. The latch was this sort.
It only had two notches to click closed onto and it had sprung open one of them.
I could see the ground through the door gap and feel the air rushing in.
At a time like that you realise how heavy three beer drinking Land Rover drivers are and how your life depends on 3mm of latch and your own grip on a bit of angle iron.
Never, ever doing that again. Pilot was stupid and didn't check we were safe before taking off and didn't care when I was complaining about it.
