Last time any of those people on board will get on a plane, I'm sure. Especially the guy who had his shift ripped off him... F that!

Statistically air travel is very safe, getting in a car and going to the supermarket is probably more likely to get involved in an accident. Of course, when a plane crashes, it's more likely to seriously injure or kill a lot more people but then that's the case if a bus crashes as opposed to a car too. This looks to be some sort of manufacturing defect - it is noticeable that the shape ripped off is a door shape, and that Alaska got their 737s without an optional door in that place. It's possible the process of converting that was defective and maybe it wouldn't be something that might be picked up in maintenance. When you're travelling a long way up and at speed the pressurisation is much different so anything which could be weaker may well pop over time. |

Commercial flights are by far the safest per mile travelled (Motorbikes are the least safe).
Private flights however have a poor record, they are the second worst, so if your going to fly, do it on a commercial flight. |
Re: Boeing 737 Planes Grounded
The door that failed was blocked as its not used on the seat configuration used.
The plane was only 2 months old. As has been said, you have more chance dying on the way to the airport than flying to your destination. |

The door that blew out is apparenly held on by 4 bolts, that really doesnt sound like many.

It may interest you to know that the tail of the Airbus A300, the Airbus equivalent to the 737, is only held on by three bolts. And in 2001 a pilot over stressed the tail ( or vertical stabiliser) by wiggling the plane to avoid wake turbulence from the plane in front, and it sheared off. The plane crashed killing all 260 on board. https://en.wikipedia.org/wiki/Americ...nes_Flight_587 https://www.researchgate.net/figure/...fig1_279693318 |

Wow ..... my front door is held in place by more bolts.

(The tail fin of that Airbus withstood more than doubled its design tolerance before failing - the ‘wiggling’ Pierre described was actually a series of extremely violent and excessive control inputs by the plane’s first officer, who had been poorly trained on how to escape the emergency situation they were in). In the present case, Boeing has allowed yet another flawed 737 Max 9 out of the factory. The type is turning out to be a disaster. Netflix’s damning documentary on the company (Downfall: The case against Boeing) is well worth watching. It focuses on the software issue that caused the autopilot to crash more than one of them and concludes that the corporate culture at Boeing has gone rotten, killing off the safety culture the company used to be famous for. The blanking plate installed in this aircraft where there would otherwise have been an optional emergency door is either badly designed, or else its installation at the factory was botched and then quality control failed to pick it up. Either possibility is unnerving. |

It wasn’t so much the software issue, which was an attitude correcting program. The plane flew fine, if you knew how to fly it. As always it was about the money. History…..Because the 737 airframe is essentially the same one for 55 years, but engines have changed, and for modern engines to fit the 55 year old frame they have to be slung way forward, therefore making the plane slightly unstable. Boeing fixed this with software, as Chris says, but they filed the change as BAU, therefore not requiring retraining of pilots, because that is very expensive. So pilots did not not know that this software would make corrections to the plane’s attitude independently of the pilots inputs. So, when you took off, you had the plane pulling up, so the pilot pushed down, and vice versa, which led to two crashes. It was simply cost cutting over safety. Unforgivable, especially in aviation. |

This morning’s developments:
- this specific aircraft had pinged pressurisation warnings in the cockpit on multiple occasions and Alaska Airlines had restricted it from long-haul flights over water in case it needed to land quickly. - a teacher called Bob found the missing piece of fuselage in his back garden in Portland. - an iPhone sucked out of the cabin during the emergency has been found, in working order. https://www.bbc.co.uk/news/world-us-canada-67909417 |
