Bill you are working with outdated info on 427 and colorado springs.
I suggest that you get last month's (maybe 2 months ago now) Air and Space magazine. It has a long detailed description of the investigation and how they thought what you thought was true untill they found the mechanical defect in the 737s rudder that causes it to reverse (You step with right foot and it goes left) and then JAM at the stop. The problem is real and now known and turned out to be common to the redesigned rudder. The aircraft have been speeded up to faster than crossover speed as a near term bandaide till the fleet can be fixed.
Your hypothesis was given a VERY serious look at by the NTSB and the FAA and everyone else untill the real mechanical defect was found. We have found enough defects in the A300 as well.

PS. If you can't get a hold of Air and Space shoot me your address and I will copy it and forward it to you if I still have it
