thanks cosmo, I will check them out.
here is a good URL on the trident question:

I do think a human being can easily flip the wrong switch, or retract flaps at the wrong time and we must chalk it up to being human.
I flew a very nice plane at one time called the North American -Rockwell Sabreliner (40). The leading edge devices would automatically extend or retract based on the aerodynamic forces on the wing. Fancy springs calibrated for a certain relative wind/airspeed. The pilot could only control them by changing speed (aoa I suppose really). Right on the cusp of the right speed they could sort of bounce from extended to retracted and back.
I think the idea of slowing things down by calling out speed, manipulation, result and all is excellent. Sadly the chumps in charge have seen fit to do otherwise. Their rationale is that it couldn't happen that way here. Yeah, right!
fly safe
