How safe are these? I'd be worried about missing or incorrectly torqued bolts etc such as with the Alaska airlines 737 max9s. God knows what the production line is like at Boeing these days.
Those engines seem impractical, its like Tim Allen got his hands on it, its like a big block muscle car, sure its cool but I wouldn't put the kids in it, somethings bound to go wrong.
Flew the 737, 757, 767, 777. The Triple 7 is the greatest airplane flying today. 10,000 hours in all over the world. An amazing machine built by amazing engineers.
