    On the day of the accident, however, the lights at the intersection where the Dash-8 entered the runway were malfunctioning, according to a notice to airmen that went into effect on December 27. Pilots are expected to check airport NOTAMs.'

    Japan is going to hang somebody over that. It's not like the west, they really go after negligence and sentence the people responsible to long prison terms.

    The Coast Guard pilot is pretty much finished too.

    The US had two commercial air travel deaths last year. Zero
    commercial turbojet crashes. The cheesemakers are doing OK.

    That's the bottom of bottom line statistics. And it does not mean they're doing okay.

    Now it's turning out the MAX 9 fleets are full of defective installations on that door/ window thing. I wonder if that has to do with the union busting South Carolina operation.

    The scary part is the door/ window is just the one they know about. How could anyone be confident in that aircraft again? They need to collect some samples for a complete teardown and inspection of every last rivet.

    Alaska Airline is in really deep doo-doo. Their pilots had been reporting and documenting intermittent alarm indicators for loss of cabin pressure, and the airline took it seriously enough to prevent the MAX 9s from being used on their ocean flyovers to
    Hawaii.

    Excellent. Safety first.

    That makes them sound like a bunch of amateurs who don't know how to resolve problems in a reasonable way. Makes one wonder what else they've screwed up by sweeping it under the carpet.

    Fly Air Uzbekistan if you think it's safer.

    In the USA, the airport escalators are more dangerous than the planes.
