The aircraft got delivered in August! Pretty rare to get a modern Airliner involved in the crash these days, but anything can happen. Very sad! Hopefully they can figure out what happened in the near future.
This is the second crash of a brand new Lion Air 737. In the first one, there were no fatalities (the plane crashed in the water while trying to land), but unfortunately this new accident was not survivable.
Wow, that's some serious glitch. Reminds me of the Qantas A330 that did a random dive due to a faulty ADIRU but in this case it happened just at 5000 feet giving very little room to bring the flight back under control.
