Wheel of a Delta Boeing 757 flew off while it was preparing to take off at ATL
- interestica 3y agoOkay this is too on-the-nose in terms of metaphor
- weard_beard 3y ago“The wheels are coming off”, you say?
- georgyo 3y agoVery relevant skit https://youtu.be/3m5qxZm_JqM?si=jrExOJWxTPIVECel https://youtu.be/3m5qxZm_JqM?si=jrExOJWxTPIVECel
- EdwardDiego 3y agoCardboard is right out. No cardboard derivatives.
- mindcrime 3y agoBut are these planes built to very rigorous aerospace engineering standards??
- crossman 3y agoActually it sounds like the problem is it was no longer on the nose...
- brucethemoose2 3y agoLooks like a misleading tweet, in the video it sounds like the tire came off like it was a flat maybe?
- EarthIsHome 3y agoIn the video: > It just rolled off the runway behind you.
- pimlottc 3y agoThat doesn't really answer it, most tires hold enough shape to be able to roll on their own.
- daveslash 3y agoYou're right, they do. And I'm certainly no expert, but I have a more difficult time imagining a tire coming off the wheel intact without some catastrophic "blowout" impeding it's ability to smoothly roll than I do imagining a whole wheel coming off.
- jagged-chisel 3y agoLeak, low pressure becomes no pressure, various lateral forces encouraging the tire to fold this way and that under mass, and soon enough the tire alone escapes its tormentor (because it’s being bent and pushed in ways similar to those that originally encouraged it to pop onto the wheel) and scurries away toward an unsuspecting fence.
- daveslash 3y agoWell, I did say that I was no expert. This explanation makes sense. Thank you.
- mvdtnz 3y agoAmericans commonly use "tyre" and "wheel" interchangeably. Drives me nuts especially in motorsports where the distinction is important. But it is what it is. This was a case of a wheel coming off.

- bequanna 3y agoHere comes the confirmation bias. Now, every issue with a Boeing plane will be noticed, reported on and magnified. I'm not saying this is necessarily bad as there actually do seem to be some significant issues at Boeing. Hopefully, the result is an intense shakeup resulting in increased focus on quality.
- AlexandrB 3y agoThere were plenty of rumblings about Boeing's poor quality control after the MCAS issues. Didn't seem to change much. But then again, maybe this is the straw that breaks the camel's back in terms of PR.
- gregoriol 3y agoMaybe different problem here: while MCAS was an engineering problem, door was an assembly problem, here it would more likely be a maintenance problem (757s have been built years ago), which is on the airline or not directly Boeing?
- Jtsummers 3y agoYes. The youngest 757 is 20 years old, oldest is 40. This would be a maintenance issue of some sort.
- sokoloff 3y agoThe last 757 flew away from Boeing in 2004. It's surely the case that the landing gear issue that happened today has little or nothing to do with Boeing's quality control and everything to do with airline maintenance actions/responsibility.
- mvdtnz 3y agoI guess that's a consequence of directly causing the deaths of 346 people. We are right to scrutinise them harshly.

- SoftTalker 3y agoAll airliners occasionally have problems with wheels and/or tires. And occasionally have cracked window glass. And occasionally have engine failures. And occasionally have pressurization problems, Read avherald.com for a few days and you'll see that it happens to Airbus, Boeing, Embraer, Bombardier, and others. And with the number of flights worldwide, some kind of problem serious enough to cause a return to the aiport or diverting to an alternate happens almost every day. Boeing has some serious questions to answer about their engineering and QA processes. But attributing random normal problems to that just confuses the issue.
- pavel_lishin 3y agoIs a wheel coming off of the front of an airplane a "normal problem" on par with an engine failure or a cracked window glass?
- bombcar 3y agoVarious things related to it are common "enough" that you can find discussion around them - for example the Airbus sideways landing gear: https://safetyfirst.airbus.com/landing-with-nosewheels-at-90-degrees/ https://safetyfirst.airbus.com/landing-with-nosewheels-at-90... Of course, these are "normal problems" that shouldn't happen and need to be investigated, but it's not quite "the front fell off": https://youtu.be/3m5qxZm_JqM https://youtu.be/3m5qxZm_JqM
- cm2187 3y agoPlus B757 stopped being manufactured in 2004 so whatever problem this is, is unrelated to recent boeing manufacturing problems.

- mpreda 3y agoAnd all airliners ocasionally have two complete-loss crashes a few months apart? (346 people died in two similar crashes: Lion Air Flight 610 on October 29, 2018 and Ethiopian Airlines Flight 302 on March 10, 2019) https://en.wikipedia.org/wiki/Boeing_737_MAX_groundings https://en.wikipedia.org/wiki/Boeing_737_MAX_groundings
- gregoriol 3y agoIt seems that the departure has been delayed by a 1h20min but the plane did take off?
- pavel_lishin 3y agoThey pulled the donut out of the trunk and slapped it on.
- paulpauper 3y agoIs this going to become a 'thing' in which every airplane malfunction becomes a major news event.
- xnx 3y agoFor a few weeks anyway. Attention is fickle.
- ethbr1 3y agoGreat visualization of the outbound stack in the video. I'm sure ATC was super happy to have orderly departures thrown into disarray.

- Flatcircle 3y agoHad a physics teacher in highschool, worked on a submarine. Told me that with government equipment like submarines, workers replace parts based on dates regardless of the wear and tear of the part. "If this screw is supposed to last 10 years, we're ordered to replace it in 7 years regardless of the condition." With for profit companies, they'd try to push the parts to last 12 years instead of 10 by inspecting them and confirming they're still good. Saving money this way isn't too big of a deal if you're McDonalds and it's an ice cream machine. But if it's a for-profit airline it can turn into a problem.
- lawlessone 3y agoI've heard the word AI being used around this before... and it scares me.
- wenc 3y agoWhy? It’s just a marketing term. Most predictive maintenance models are ML or statistical learning models and have a great track record. Some call it AI to sound hip (you can any ML model AI these days) but it’s probably just a standard model from reliability engineering.
- wenc 3y agoIt’s called predictive maintenance and it is the norm in many critical industries. Replacing equipment every fixed number of X years (no matter what the condition of the equipment is) is wasteful, costly disruptive and does not actually guarantee better reliability. (although it makes people feel better). Most predictive maintenance is done with data — updated sensor data processed through a mathematical model derived from principles from reliability engineering. In a sense it’s actually more realistic than the X years model (which is a once off number derived from some reliability model too but doesn’t have the benefit of being updated with real data — it’s usually an overly conservative number) https://en.m.wikipedia.org/wiki/Predictive_maintenance https://en.m.wikipedia.org/wiki/Predictive_maintenance There is no evidence that predictive maintenance is the cause of Boeing’s mishaps.

- JCharante 3y agoThis happens from time to time for all aircraft models. It's why you should never be in the direct path of an aircraft taking off if you're plane spotting.
- callalex 3y agoRemember when every train derailment was 100% evidence that the USA was a failed state like Ancient Rome? That period lasted for a few months, I can’t wait till this one dies the same death.
