Fresh Bloomberg report states that a deadheading pilot in the jumpseat saved the previous day's Lion air flight from crashing by disabling the MCAS system. The flying pilots didn't know what was happening and were working through their checklist. Report -

Also, apparently as per the voice recorder, the pilots of the Lion Air flight that did crash were following their checklist, but ran out of airspace to work with. This is BAD BAD for Boeing! Wonder if the US delivered planes were simply different or were US airlines given advanced warnings and provided additional material to train their pilots - but multiple US pilots have reported the system acting up and causing issues. Luckily no incidents in the US.
