Jump to postI don't think 10 seconds of continuous trim input is really a "short burst." It is a myth that MCAS runaway and "normal" runaway are so different that a pilot would not be able to recognize MCAS runaway as a runaway stabilizer. I would be willing to bet that when the final repor...
Jump to postUnfortunately there are many people who believe that the pilots are obsolved of all blame because they are dead -- that's not the way it works. As long as you even hint at any pilot blame you will be trashed.

Except the picture appears to be a 757. The 757 does not have fuel jettison (ie dump) nozzles.
Relative to the back in service date, I believe Boeing indicated after they got dinged by the FAA, they said September would be the date for providing paperwork to the FAA, so in service would be 2-3 months after that if all went well.
