Profit Max,
Please... we do NOT know yet "who" did "what".
Of course we can now switch to endless speculation on what happened, like with the Congonhas, Brazil A320 crash (remember the number of pages that generated?).
Like we can speculate endlessly on how the people in charge interpreted the aircraft moving as a parking brake failure. So they stood on the brake pedals. Took a few seconds to realise that didn't work either, so their diagnose was wrong. By the time somebody changed his mind and chopped the throttles, they were at 30 kts.
It's hardly as if it were a day-to-day issue for the average pilot. How many here on the forum do pre-delivery engine runs for a living?
So let's hold off, until the guys in hospital have had a chance to have their say.
