POST #8
Dan Air's original 727-100s were the first on the U.K. register and as such were required by the CAA to have a Stick Pusher fitted i.e. a pneumatic actuator that snatched the column out of your hands (nearly). The system fitted was similar to that used on the 1-11 and, presumably, the Trident.
If I remember correctly, but I may not - it's been a long time !, the -200 series aircraft were allowed onto the register without the pusher fitted and relied on the standard stick nudger, a spring device which was much more gentle.
