Canada has just grounded the 737 MAX8 and now has banned it from their airspace. More knee-jerking than a Tennessee late summer barn-dance hoedown.
I remember a while back in the 90's that the 737 used to have issues with their rudder that sometimes caused it to fully deflect. Interesting that it went on for years - PCU secondary slide jamming from cold fluid. FAA ordered all PCU's replaced in 2002 and mandatory training for unexpected movement of flight controls. To my knowledge, that's now a standard in all training no?
My point is, three crashes yet none of the 737's were grounded. Yet, in our socially sensitivitivity hyper-excited society, we tend to overreact than to objectively and calmly make better decisions. Grounding ALL MAX8's is an over-reaction. Sure, any crashing plane is a horrible accident, but putting unneeded stress due to our new stupid-social norms is starting to become irritating. /RANT OFF
