    This one didn't work out so well.

    This news is a little stale; but, I don't remember seeing it here. Flying with no moving parts.

    MIT Scientists Created A Plane That Flies With No Moving Parts
    The plane uses an ion drive to propel itself through the air — in absolute silence.

    Imagine a plane with no engine ― with, in fact, no moving parts at all ― not just gliding like a paper airplane, but being propelled through the air. Scientists at the Massachusetts Institute Of Technology (MIT) have made it a reality using an ion drive.

    The project’s lead researcher is Steven Barrett, a professor at MIT’s department of aeronautics and astronautics. Barrett said he was inspired by the show “Star Trek,” in which spacecrafts travel rather silently and without the use of traditional fossil fuels.

    The five-pound plane’s ion drive consists of electrodes near the front with a positive 20,000-volt charge and air foils near the back with a negative 20,000-volt charge. The electrodes positively ionize the surrounding air molecules, which are then attracted to the negatively charged air foils, creating an accelerating ionic wind to propel the craft. And with no propellers, turbines or moving parts in general, all this is done in complete silence.

    Their most successful sustained fight so far was about 10 seconds, or a distance of 60 meters.

    Barrett says that while implementing this technology in commercial travel is a long way away, the soonest use might be in the advancement of drone technology.

    A journey of 10,000 miles begins with a single step.

    That'll buff right out.

    (and r/CatastrophicFailure is worth a sub if you reddit).

    That is one lucky fellow there.

    Posted By: maryyugoYou might want to avoid the 737-800 max if you have the choice... ...until it's fixed.

    Not much chance of fixing that one.

    Early days yet but could this be another case of a failure properly to integrate artificial and natural intelligences?

    If a pilot has to ask "What's it doing now?" the answer might be "it's trying to kill us all".

    Yeah. I hope the recorders are in useable condition after the aircraft apparently augured straight in pointy end first. I read in one place, unconfirmed, that there was a distress call.

    Let's hope it was not a remote hack from a satellite

    Its been reported that in both crashes the pilot radioed for permission to return to the airport.

    A scenario that seems to fit the reported automated air data from the airplane is this: The dreaded secret system that is supposed to "aid" in stall recovery trimmed the aircraft nose-down, either in response to a faulty sensor or just stupid coding. This causes the pilots to pull back on their yokes (decent Boeing yokes, not silly Airbus sidesticks with no force feedback) in an attempt to raise the nose. They are successful, the secret system fights them again, they need more and more force pulling their yokes back, up to 40 kg reportedly, and suddenly one of them remembers the Trim Disable switch on the center console and flicks it to OFF. Suddenly the force on the yokes disappears, but the pilots are still pulling back. So the trimmable horizontal stabilizer is running rapidly back to neutral, the fake yoke force is gone, the pilots are still pulling fully back, the engines are at full power.... a zoom climb results, the airplane does a beautiful wingover or stall turn, and augurs straight into the ground from a relatively low altitude and high airspeed. The crater is deep and the impact was so forceful and followed by the fire from the fully fueled airplane that there is nothing left big enough to bother with. The flight data and cockpit voice recorder data safes are going to be buried meters deep in that soil.
