> This is the new reality for all airliners now that there are much more rigorous mandatory safety analyses in place.

That's an interesting roundabout way of saying that they were not following the certification requirements before, and that it now takes much longer for them to actually conform to the rules they should have followed in the first place.

> The 777-9 just happened to be on the edge of certification when they came along.

Yeah, killing 346 passengers due to extreme negligence will do that to you.. These pesky FAA requirements standing in the way of business..

And more generally, door blow-outs during pressurization tests and engine pylons failing are maybe not things that can be blamed on certification rigorousness..
