My wife's plane was about to take off (moving) but then stopped. I just messaged her to check once I saw the news. Sounds like the people onboard weren't given any info as to why. They're still on the runway waiting.

Hello from the ground

Physics says all planes land. I guess eventfully would be diversion (maybe to Canada lol) or Mayday Fuel (but you probably won't know it happened anyway - it just means some reserve fuel will be used).
