What's the back of the envelope on whether the 737 Max is more dangerous than driving? 1,300 aircraft have been built since the first started flying in 2017, with two deadly crashes. I don't know how many miles those have accumulated, but presumably it's of order 4k miles per day per aircraft, and maybe 3 years (1000 days) of flying to date per aircraft on average, giving a very rough estimate of a few billion miles?…

You can’t compare like that.

If you drive into a tree and get maimed, it’s different to someone else driving you into a tree and maiming you.

When you’re welfare is in someone else’s hands, they need to better than you would.

Two of those are manufacturing mistakes, and it seems likely the door one is as well. Not that that helps the passengers, but they're not systemic design flaws. That anti-icing system is deranged, though. They effectively installed a timed detonator on the engines and want a safety exemption for it.

Ah you’re right. They’re not design flaws, just manufacturing issues, so sign me up for the first flight when the max flies again… People falling out the sky because the wing falls off because someone forgot to bolt it on aren’t going to care if it’s a design issue or a manufacturing issue. Boeing is doing both, so the blame lies with them either way.

> Spirit [AeroSystems] is responsible for the entire fuselage, including the cockpit, in all Boeing jets, and the entire fuselage for the 737 MAX models, according to the Seattle Times.

So Boeing didn’t actually manufacture the plane. But they are still responsible for ensuring its manufactured correctly.

How to avoid the 737 Max? Fly only airlines that don’t have it. Luckily there are still a few around in Europe. Since the two fatal crashes I have avoided doing flights with 737s.

I have made the decision that unless I absolutely can’t avoid it I am avoiding Boeing for the near future entirely. But a 737 max is full no go for me no matter what the situation is. I will do multiple stops before stepping foot on one. Personally I fly exclusively JetBlue in the US and they use Airbus almost exclusively. They have a few of whatever that other brand is. No Boeing.

Please don’t read this as a defense of Boeing, especially the MAX series aircraft, but from a flyer-safety standpoint the statistics show most Boeing aircraft in operation today are extremely safe.

The post-200 series 737s, not including the MAX, have some of the largest accumulated flight miles and lowest incident rates of any aircraft ever. The 777 and 747-400 also have exceptional safety records. Even the aging 757 and 767 fleets have only slightly higher rates. The 787, though relatively newer and with plenty of documented early issues has had no passenger fatalities that I’m aware of.

Just some food for thought.

Good book describing the cultural change from engineering-focus to business-focus of Boeing: * https://www.goodreads.com/book/show/55994102-flying-blind * https://www.penguinrandomhouse.com/books/646497/flying-blind...

Has there been any push to break up Boeing?

Boeing was reasonably broken up until merged with McDonnell Douglas.

Two days ago before we got on one of these planes I said to my partner “don’t worry, it’s the most scrutinized plane in history”.

Yeah it's really not. Age is the only thing that will do that.

It's hard to know how much time has to elapse before all the problems have been teased out though.

Anyone who thought the DC-10 was in the clear after its cargo door problems were fixed was in for a nasty surprise a few years later when an engine fell off of one at O'Hare, but if the industry had written it off after that incident they'd have missed out on 35 years of an otherwise reliable plane.

We really need another player in this space. There are these startups like Boom etc. Trying to do new things, we should do one that's just normal planes, made right.

Boeing made the 737 NG until 2019. It also allegedly had issues with the contractor Ducommun making the airframe, including "hammering alignment holes into place". But it wasn't nearly as problematic of a plane. The Max is a desperate attempt to compete with the A320 neo ("new engine option"). It is the aviation efficiency gain equivalent of a die shrink, except these engines get bigger, and while Airbus had space to…

> pilots not having to do an entirely new type certificate And consequently, their intention seems to be to bend the rules about the validity of the existing certifications to the max (no pun intended). At what point can an agency rule that Boeing no longer follows the spirit of the pilot certification rules?

Brazil has decided that since the first day.

And honestly, it didn't create any huge roadblocks for Boeing.

When did they ground it? I'm looking at the tail number on FlightAware and it's on a scheduled flight to SEA since 9am.

It seems like they grounded all of their 737 Max 9 fleet immediately after the incident. But apparently they have begun inspections and returned some of the fleet to service - https://twitter.com/jonostrower/status/1743668287106678866 and https://twitter.com/AlaskaAir/status/1743677307644944797
