As useful as some discussion here has been, continuing rules violations will lead to suspensions and thread closure. Please think about that before posting.

The purpose of FT is to be an informative forum that, in this case, enables the UA flyer to enhance their travel experience. There are other forums for different types of discussions. This thread was had wide latitude but that latitude is being abused.

Bottom line, if you can not stay within the FT rules and the forum's topic areas, please do not post.
And before posting, ask if you are bringing new contributing information to the discussion -- not just repeating previous points, then please do not post.

Discussion of Boeing's culture or the impact on Boeing's future is not in scope. Nor is comments on restructuring the regulatory process. Neither is the impacts on COVID on the general air industry -- those are not UA specific and are better discussed elsewhere. And for discussion of UA's future, there is a separate thread.

Additionally repeated postings of essentially the same content should not happen nor unnecessarily inflammatory posts. And of course, the rest of FT posting rules apply including discuss the issue and not the posters.

The Moderator team feels there is a reason / need for this thread but it has been exhausting to have to repeated re-focus the discussion -- don't be the reason this thread is permanently closed ( and get yourself in disciplinary problems).

Stick to the relevant topic which is (repeating myself)

United does not fly the 737 MAX 8 that has been involved in two recent crashes, but it does operate the 737 MAX 9.

How to tell if your flight is scheduled to be operated by the MAX 9:

View your reservation or flight status page, either on the web or on the app. United lists the entire aircraft type. Every flight that is scheduled to be on the 737 MAX will say "Boeing 737 MAX 9." If you see anything else -- for example, "Boeing 737-900," it is not scheduled to be a MAX at this time.

The same is true in search results and anywhere else on the United site.

For advanced users: UA uses the three letter IATA identifier 7M9 for the 737 MAX 9.

All 737 MAX aircraft worldwide (MAX 8, MAX 9, and MAX 10) are currently grounded.

RE UA I think it's a no-brainer to ground their 737-max (even if they aren't the 8). Even it's just for the sake of PR. I am amazed the US airlines (and particularly UA as they have only a few) are dragging their feet on grounding the max. at least ground the 8. Going forward I will avoid all versions of the 737 max until the problem (s) are clearly fixed .... I didn't avoid Malaysia airlines after their two unlucky incidents ....

Reuters is reporting several witnesses saying smoke and items coming out of plane before crash. Sounds very different than the control software issue cited in prior crash.

Tamirat Abera, 25, was walking past the field at the time. He said the plane turned sharply, trailing white smoke and items like clothes and papers, then crashed about 300 meters away.
Regardless, I am happy to see UA being proactive and understanding about people who want to avoid the MAX variants.

The problem with these reports (and similar reports the plane was on fire) is that its very hard to match them with the flight path that is commercially available. The only way that you would see "items of clothing" flying out would be some type of a bomb that blew open the hold, and that would not match the up down, up, down flight path. I for a while thought that their might have been an engine fire, but the pilot did not report one.

If there are signs of an engine fire or bomb we should know relatively quickly.

Eyewitness reports, especially from people generally unfamiliar w/aviation, are notoriously wrong. See TWA 800.

Plus - we know that the pilots radioed a problem. If there was a fire/explosion don't you think they'd said that and/or we'd already know that (debris is more than one location)?

I saw that too... interesting, but I take the observations of crash observers with heaping spoonfuls of salt. Unless they have some relevant basis of knowledge, it's hard to gauge the reliability of their recollection(s) after such an unusual, overwhelmingly dramatic event.

If as is being suggested the issue relates to air-frame deficiencies and a poorly performing/executed fly-by wire system to try to make up for these deficiencies, then the problem will extend to the MAX9, which has the same basic systems. If anything, I would expect the flight performance of the MAX9 to be even more sub-optimal than the MAX8.
This is exactly the kind of illogic that plagues knee-jerk reactions made in the immediate aftermath of a crash.

If passengers are uncomfortable flying on a given type because of their personal perception of safety, then by all means, they should change their travel plans. Problems arise when people start stringing disparate facts together in a public forum, reaching unsupported conclusions, and making proclamations that aren't relevant to the underlying matter.

Smoke before crashing is VERY relevant. VERY revealing and VERY different than Lion Air. Causes? depressurization from fire, explosion, structural failure and on and on. It's nice to know what's up all being aviation enthusiasts, travel enthusiasts and professionals alike. HOWEVER, we need to sit tight...not make any judgments. But, I have a suspicion this one is going to be very different than the Lion Air.


And I dont agree with you that the pilot could recognize the issue. Remember ValuJet crashing in the Everglades? fire. pilots had no idea. one contained crash zone. many many possibilities and WAY too early to discount or give credit to anything. But multiple people seeing smoke makes me wonder....on a clear sunny day remember!

Good PR by UA. It probably helps that the MAX isn’t a material % of their fleet miles flown. Winding them down semi quietly until the investigation is complete could be done without massive disruptions to schedule.

I booked away from MAX a few weeks ago due to poor reviews of seats and tiny lavs.

What does it say when you look at the trip details? (My Trip tab / Manage Reservation). It should say something like "Boeing 737-900." If the flight is scheduled to be operated with the MAX, it would say "Boeing 737 MAX 9."

In other cases--DC-10s, for example-- fatal mistakes were corrected and the AC served for decades.
Mohawk BAC 111 crash 1960s. Some type of fluid leak in the tail cause a fire & the crash. Problem identified & corrected.
DC 10 - AA engine flying off, corrected. Another the cargo door latch caused a crash. Identified & corrected.
In the 1960s there was a book about the 727 being the Libeled Aircraft after a series of crashes.

Back around 1970 there was a book published that described airline crashes over the prior 20 years and their causes. Flying is so much safer today. Just will have to wait and see the cause with the 737 Max.

The few times in your life where the plane is struck by lightning when the same model plane crashed two weeks before, or the landing gear has to be manually be cranked down & captain not sure if locked in place so you land with passengers in braced position in the event of crash (US Air), or it takes a half hour of to get the landing gear down on a Continental DC10 & crew starting to prepare for a crash landing.- this sort of makes you think twice before booking until issues resolved, if you are travelling with family members.

The pilots of ValuJet 592 were well aware of a smoke condition and a likely fire. Whether they knew with certainty its source or precise location is unknown, but it is evident they were trying to get the airplane on the ground as soon as possible; sadly, they were either incapacitated or lost control of the airplane before they had the chance to carry out an emergency landing.

Reportedly, an ET302 pilot communicated a controllability issue and requested immediate return to ADD. There is no mention of any other sort of catastrophic occurrence (fire, explosion, decompression, engine failure), but we'll soon learn whether any other major systems, unrelated to flight controls, failed or were malfunctioning in this case.

Ah thanks for the tip. It doesnt say anything about MAX, just Boeing 737-900 and Boeing 737-800

Not all MAXes are created equal. My best was AC 7M8 in Y - the entire experience was just wonderful - mind you this was a cross country trip (SFO-YYZ). My least best experience was AM 7M8 in J. Still, I have had generally positive experience on the 7M8 & 7M9 overall.

yes, all true. VJ592 was a smoked out cabin and pilots suspected (rightfully so) fire...but they had no idea as to the source or really what was going on...... Also we dont know the nature at all yet of the distress call. In fact, as far as I saw, only the ET CEO made that claim so far. (maybe updated) But a mechanical catastrophic event near, around some control hydraulic (as one example) could lead to control issues.....IDK, I am NOT a pilot or a mechanic....just an aviation enthusiast, frequent flier and follower of many past airline incidents...but if the witness who saw smoke coming out of the aircraft prior to impact is corroborated in in any way, it is a major early on detail that significantly differentiates Lion Air from ET.

Witness accounts I was wondering about

https://www.reuters.com/article/us-e...-idUSKBN1QS1LJ

Smoke and debris trailing, making a turn then diving

A possibility is bird strike damaging one or both engines, them stalling on that turn

More facts to come from the professionals
