Right, so this problem will be isolated, inspections done and doors fixed. But what about the massive unanswered question left hanging - what else has Boeing's "quality control" regime missed? I know I'll not be getting on one for a good few years from now till they prove themselves. [No d...

Re: Unconfirmed: AS1282 PDX-ONT decompression event, returned to PDX

This is going to hit BA hard. Not as bad as the other 2 max crashes but a bit less similar. They only positives is no one died and it was on a Friday evening after markets are closed for a weekend.

Not to put a fork in this deal, but what happens if the FAA does not certify the Max 10 by the end of the year? Is the deal contingent on this?

Drones shouldn't wasted on trucks. They would obviously save them for more high value targets. There is no higher value target than a fuel truck when it looks like your enemy's logistics are causing them trouble. Hit one fuel truck, you might reduce a squadron of tanks to becoming a static display.

Re: Boeing 737 Max Netflix documentary- Downfall

It has been stated that Boeing assessed the likelihood of the pilots as not taking appropriate corrective action as a 1-in-150 risk, which combined with the small fleet size of the 737Max permitted Boeing to proceed without grounding the fleet. Also quite efficient with the truth. Perhaps Boeing pu...

When the 77W retirements start we will see if they choose a smaller aircraft or a 4% larger one. It will be very interesting to see.

Doing it for a living, even winning awards, does not mean you're good at it. Plenty of managers win tons of money before high-tailing it ahead of catastrophic failure. Assumptions can be eliminated.

I agree. Most engineers will tell you most automated test suites are garbage.
