As to..
Agreed as to parameters of controlled flight. Motion of any body that has no aerodynamic stability, or stable CG cannot be predicted without a great deal of data. In the sixties, the supercomputer was an infant, and chaos was also in infancy.
The CAB had a purpose outlined in its remit. After the third impact, nothing was quantifiable such that a reward of any kind could be had relative to “preventing” such an accident in the future.
The single cable system was the underlying culprit, and nothing could be done to make it redundant, certainly not at reasonable cost. The “fix”, one assumes, is more frequent inspections (not terribly difficult) involving pulling up some carpet and removing an Inpanel. More stringent repair procedures were no doubt applied, etc.
No mention of the two terrible accidents that were seemingly cured by LEAP, and I find that strange. The experiment involving flap/aileron, done by Lockheed, in my opinion, was done to eliminate the possibility that the wing had been partially destroyed, either prior to, or as a result of, the last take off.
Howl as much as you like, Whirl Mode was on everyone’s mind, and purposely not bringing it up was a political move.
IMO
