I just read that the software update for MCAS (the Lion Air crash cause) had been delayed and isn't rolling out until next month. If that's true, seems to raise the probability of this being a similar MCAS issue.

Way to early to speculate as to the cause. You could raise the possibility as to a number of reasons as to what happened.

  The parent comment merely said delayed MCAS training would make it more likely that it was the cause. That seems like an obviously true statement... If the training had happen, that would obviously make it less likely. Given the number of other similarities to the Lion Air crash, I think the parent comment was being pretty conservative in their speculation (at this point, I'd be surprised if it _wasn't_ MCAS related).

    Quick clarification: it's a software update to the plane's MCAS (I think automatically disabling it when the pilots are trying to adjust trim themselves) that's been delayed, not training.

  I mean this is a comment section on HN, surely this is where speculation can occur?

    So, I wonder how much credence my comment would get if I proclaimed: "My guess is both pilots fell asleep right after takeoff but before they could get the autopilot engaged, so the plane plummeted to the ground because no one was awake at the controls."

      Probably very little, but there is nothing stopping you making that statement. However HN usually has a decent signal/noise ratio so it's worth discussing here at the very least.

  A messenger of Manwë pulled it out of the sky. It was clearly marked speculation. If we are not allowed discussions about possibilities we can kill off comment fields right now.
