Basically any meat is completely off the table, as with personal cars, and probably standalone houses. If I’m given the choice between not having kids and not flying to see my family for holidays, I’ll take the no-kids option.


That was just their vertical speed at the time of impact. In normal flight, it’s usually zero or close to it. This thing was falling fast, possibly faster than just a freefall.
