You'll all be delighted to know that the BBC report one pax:
Passenger Marty Martinez posted a brief Facebook live with the caption: "Something is wrong with our plane! It appears we are going down! Emergency landing!! Southwest flight from NYC to Dallas!!"
After landing, he told CBS News that it felt like the plane was "free-falling".
At least the BBC had the decency to put "free falling" with inverted commas but did not explain that it might have
felt like free falling but was a controlled emergency descent as per SOP for every commercial airline. They had the chance to educate (just a teeny bit) but, I'm guessing, the lack of proper staff on hand who have knowledge to be applied, could be a factor.
