Don’t get me wrong - if I had to land that plane, I’d likely have overrun the runway too. I’m not saying it’s easy, only that it appears to me that they were operating well outside the documented parameters that are the pilot’s responsibility to know.
I just looked it up, and a 767’s Vref is 122-165kts, with Vref at max weight at 144kts. They touched down at 158kts, nose down. The approach was ~35kts over speed, they were above the glide slope, and not bleeding speed fast enough to sink - so they dropped the nose.
From what I can see, they were screwed the moment they touched down - the last moment they had a reasonable opportunity to abort was when they decided to drop the nose and commit instead.
