This isn’t a Boeing as much as it is a CFM the pilot apparently reported vibration issues with the engine a CFM 56. If there is an endemic issue it would require the Engines to be worked on, that would spread across the 737 line including P8, E7 and C40 as well as E3D, KC135, E6, Airbus A318, A320, A340 models which use the engine. If really bad that could include the LEAP series however we should wait and see what the post event investigation finds. Seems like this may have been a specific issue.

Yes, it can be a similar case with China Airlines Flight 120 in 2007. Engine 2 started to burn at the gate at Nara Airport. The fire had been caused by a loose bolt puncturing a fuel tank.

We indeed have to wait for the results of the investigation.

Also, it could be an airline maintenance issue, perhaps an optimist's view as I fly on these jets frequently. WestJet and Air Canada maintenance issues, none that I know of but driving from Toronto to Canada, not an option....trains...LMFAO:rolleyes:

I like trains!
However yeah North America has let our lead in railroads from the late 19th century decline to last place. However when you consider the size coast to coast of the North American continent even the fastest HSR on the planet couldn’t keep up with a standard flight. HSR is optimized for trips to long to drive to short to fly or roughly between 100-600 miles.

Yep, NA distances (with population voids in between) are real obstacles, not to mention the aviation lobby in Canada and the US.

All transit is subsidized in Both. Streets are city/state(Provence) Highways are State/Fed, Passenger rail is state/Fed, Aviation is State/Fed. It’s just easier to repave a runway than to build 400 miles of Grade separation via aqueduct. Of course the real killer is eminent domain. People get angry when you tell them that the reason they have to move is the government wants to straighten a curve of a rail line so some city folk can shave 30 minutes off a commute.

Eminent domain is primarily a US issue, not so much an issue in Canada....unless its First Nations land.

Was Hiring A CEO With A Background In Engineering The Right Move For Boeing?

Will an engineer save Boeing and rebuild Boeing's reputation?
simpleflying.com

It is about time that Boeing CEO back again to engineers after so long stay on bean counters helm. His move to relocate Boeing HQ back to Seattle hopefully also means his reign as CEO means also back to technical focus driven.

Even market analysts which mostly are Financials background are also mostly welcoming this. For a manufacturing company that now riddles with numerous technical qualities issues, there are limits that financial market driven CEO can do to sort it out. Hope the shareholders understand also that this process will take times as it is changing back from More Shareholders value driven of Mc Donalds Douglas legacy back to More Technical value driven of Boeing legacy.


Add video that being made during opening of Xinjiang - Lanzhou high speed train. This HSR line then connect to Lanzhou - Xian line which then can connect to other HSR line from Xian to the coasts, either Beijing or Shanghai.

However this line also one of most expensive line among China HSR lines being build, and also one of less utilize ones in term of passanger density. Xinjiang to Beijing HSR is equivalent to US coast to coast HSR (if US one to build HSR between coast to coast). China build the western HSR line as part of Belt and Road initiative and it is remain debatable on the economics value of that.

There're debates on how far a HSR line can be profitable. Whether single line of 600 miles or 1000 km (around 5-6 hrs trip) is the limit ? or interconnected line as Xinjiang-Lanzhou-Xian-Beijing still can be attractive for certain segments of market. However so far China Western HSR line basically still being subsidies by more profitable coastal lines between cities line HK-Guangzhou-Shanghai-Wuhan-Xian-Beijing corridors.

Personally I believe it is back to economic activities which make one lines attractive or not. China economics activities still dominate by Coastal area and Central area, thus Western area lines so far will not be going to be much profitable for long time. However if being build as part of ecosystems lines, perhaps some merits will be there,eventough will take long times to be break even.

Just to shown perspective on question between HSR vs Airliners on long distance travels.

This pro Russian aviation channel put video on first flight of SSJ-100 with Russian PD-8 engine. This is part to de-westernise SSJ-100 and MC-21 regional and medium range Airliners. This is already behind schedule but important as both Airliners are Modern design and unlike TU-214 and IL-96-400 that's still have 3 crew Soviet design Cockpit.

SSJ-100 and MC-21 are Russian Civilian Airliners future and Russian hope to replace most Airbus and Boeing in domestic operations. Something that Russia hope also later on to export for market that can not get or don't want to operate Western Airliners.

A topless passenger (don't worry, it is a man) who missed his flight was caught on video footage aggressively throwing objects, breaking and smashing structures in the gate area of Terminal 1 at Dublin Airport . The sudden unplanned redecoration of Terminal 1, occurred on Monday 17 March 2025.

Thanks for sharing.
So it seems that Lufthansa has to keep the A340-300 and B747-400 longer in its fleet, because of the delay of the delivery of the 777X.

I think the concern also applies other new aircraft that will have cutting edge jet engine technology. As for the renewal of Lufthansa long range wide bodies, not really familiar, but perhaps the larger versions of the A350 could have been an option?

After Russification version of SSJ-100, now the channel shown IL-114-300 Turboprop Russification version. Seems Russia also planning for first flight of Russification MC-21-300 soon. With this even after much delay, seems the momentum for Russian civilian aerospace industry is gaining ahead.

With Chinese civilan airliners, it will then see how far Russia and China can provide alternatives to Duopoly and Turboprop western products in international market. Still far from happening, but will see by end of decade.

A closer look at the modified/upgraded Il-114 and new built (naked) Il-114-300.
With delays in the Il-112V/Il-212 program, the Russians really have to ensure that the Il-114-300 development program runs smoothly.

According to the same Youtubechannel, production of the Tu-214 is going very slowly because of lack of proper trained and experienced staff.
The Tu-214 delivered to Red Wings in December 2023 is probably the last Tu-214 delivered to an airline.
Авиакомпания Red Wings пополнила парк самолетом Ту-214

But it seems that Red Wings added a second Il-96-400T to its cargo subsidiary Sky Gates last week. It has the registration name RA-96101.

China revealed plans of a program to start the development of a new supersonic airliner. Fox News is talking about "50 × faster than the Western made Concorde".
That sounds impossible, and other sources talking about a maximum range 50% more than the Concorde, which sounds more realistic.

COMAC is thinking big, and we’re not talking about its current commercial jets and future widebodies. The Chinese state-owned aircraft manufacturer is already

And here an article about a Jetstar flight from Denpasar to Melbourne that has been forced to turn back to Denpasar on Monday night last week, after a female passenger attempted to open one of the doors.

They are talking 50% range increase of 6,800 miles vs Concord’s 4600 miles. Though speed wise it would actually be slower at Mach 1.6 vs the Concorde’s 2.4. A target size between 28-48 pax.
Boom SuperSonic’s Overture aims for a 4,250 mile range machine 1.7 a 64-80 pax. And well an unrealistic 2029 launch date. So the Comac team might have a more realistic launch date and longer range, I expect both to slip. On the upside this might light a fire under the west to work harder.
So China v West right now still in the US favor as the Overture has been vapor for longer than the 949. With Comac yet to cut steel on the 939 and inching to the 929.

There are other even more ambitious proposals such as the Hermes Halcyon a 20 pax Mach 5 4000 mile airliner but that’s well even more nebulous.

3 program of Russification being covered in this video, the SJ-100, Ansat and Mi-38 Helicopters. Like all Russification program after the War and subsequent western sanctions, this programs aim to not only guarantee Russian Aviation Industry existence, but also revive Russian Civil Aerospace Industry.

Personally I'm more interested with progress on Mi-38, as this is already been developed for years as Mi-8/17 replacement. Both Helicopters in my opinion can attract more potential export interest then SJ-100 or MC-21 later on that are more potential for Domestic or close neigbours interest.
