On the units where I served the issue of how the SPH safety pin could be incorrectly fitted was demonstrated in the mandatory six monthly ejection seat lecture for all personnel who entered a cockpit with a seat installed. Of course it is easy to see on the training seat, but a different matter when sitting in the aircraft. There was a campaign to increase the frequency of these lectures; I wouldn't be surprised if today they have ceased altogether.
