I don't see any record of the crew having FAA licenses but maybe they did a recent US based training and the license would be pending. Does a temporary certificate have a number?

And in that Brazilian OER you will see that they identified MCAS as a category B training item. The question is what training the operators in Brazil implemented. GOL grounded their fleet after the...

The crew did not ďkeepĒ the thrust high. They ignored a control available to them and ignored its effects upon the aircraft. There was no cognitive thought process that said letís go past Vmo because...

Agreed, waive the Part 25 criteria and show the handling change in the sim. It would be nice to know what that envelope is. I'm surprised 737 pilots, pre the final incident, were happy flying an...

But you can envision continuous contact with the switches with the arm while moving the flap handle to 1. Would the thrust levers continue to advance because the rate of climb was not being acheived?

It is very strange. The only thing that comes to mind is a DC-8 crash in the 80s or 90s where fatigue might have made the pilots ďpunch drunkĒ. So we would have to know what the pilotsí duty day was...
