The Biggest Jet Engines in History Are Finally Ready to Power Boeing's Biggest Plane
More like a bull whip where just the tip goes sonic but the innards are moving more slowly
I was in a western act once as the dummy where the cowboy snapped the whip several times for effect and then lashed out at me and wrapped it around my body before the sonic tip finished up the wrap now much slower

This article popped up on my newsfeed. Seems the GE9X engines are not quite ready yet. The logistics of moving them back to the factory are a story in itself: https://www.flightglobal.com/news/ar...r-issu-460379/
GE Aviation is recalling four GE9X powerplants from Boeing to address a previously disclosed engine compressor issue that already forced Boeing to delay the 777X's first flight.
News of the recall surfaced in a 19 August regulatory filing with the US Department of Transportation (DOT) by Russia's Volga-Dnepr Airlines, which has applied for rights to fly the engines from Washington state to Ohio.

I fully appreciate the complexities of modern aviation manufacturing and production, but phrases like 'more haste, less speed' and 'it looks like carelessness' keep popping into my head. GE has already told investors that having already faced a US$600 million cashflow hit so far, it could face a further US$800 million hit if the MAX remains grounded and faces further exposure through its aircraft leasing unit.

The GE9X problems pushing the first 777X flight into 2020 and deliveries perhaps into 2021 is not helpful to Boeing or GE cashflow, given the other problems. With 150 777Xs on order Emirates won't be pleased either.

I don't know why people are wary of folding wing tips. After all we have seen how Boeing takes as long as necessary to thoroughly test all aspects of new models and ensures crews are fully aware of and trained in all aspects of the monitoring, dynamics and control systems are thoroughly documented in every detail (including simulator training for all) with sensors that are multiply redundant, ensuring no unexpected malfunctions or system faults could arise to confuse crews or cause accidents, because safety comes first. I have every confidence that the folding wing tips will have been developed, tested and documented with training to be provided to the same high standards.

Perhaps their (Volga-Dnepr's) bid was cheaper than Antonov Airlines'.

US-based airlines are unable to transport the massive GE9Xs, which ship on a stand measuring roughly 8 x 4 x 4m (26 x 14 x 13ft) and weighing 36,000lb (16,300kg). GE had used Antonov aircraft before to transport GE90s to Boeing in the early stages of the GE90 powered 777 program.

I bet you Rolls Royce wishes they would discovered the sulfidation/corrosion problem on the Trent 1000 engine in the early stages of certification before having so many engines in revenue service with various airlines.

May I suggest Boeing’s own B.744F derivative the ‘Boeing Dreamlifter’

Yes, but according to the article you posted:
It is an extensively modified Boeing 747-400 that is used exclusively for transporting Boeing 787 Dreamliner aircraft components to Boeing's assembly plants from suppliers around the world.
I guessed along those lines... But with the current feud going on between Ukraine and Russia and Antonov making their outmost to have the Volga Dnepr fleet grounded I am still surprised to see a US company contracting with them to fly within the US. Anyway a bit of a thread drift 🤔
Turbine, I don't know about the GE9X, but you can transport a GE90 (or GEnx) in a 747F - the catch being you need to remove the fan module and ship it as two pieces. That's actually fairly easy with a GEnx due to the modular design, somewhat more involved with a GE90.
Boeing looked at making the Large Cargo Freighter - aka the 'Dreamlifter' - available 'for hire' for transporting outsized cargo. Two things killed that - first off it would have complicated the certification and operation of the LCF relative to having it dedicated to moving 787 bits (read more time and money). However the real show stopper was that the four LCFs are already booked pretty solid simply supporting 787 production. In fact, if one gets pranged (or worse) and is out of service for any length of time, it'll affect the 787 production rate.
I was in a meeting many moons ago where it was proposed that they contract to build a fifth LCF while the tooling and expertise was still available - where it was pointed out that only have four would be seriously limiting (especially if one got damaged). They got turned down because upper management didn't want to spend the money.

Speculate to accumulate.

Shipping The GE9X Engine
Here is a video that depicts shipping a GE9X engine from Victorville to Peebles, GE's outdoor testing facility in Ohio:

Given that GE manufactures these engines (to my knowledge) in Ohio, can someone tell me how are GE is planning on shipping them to Washington State for installation in 777X's when production actually gets going? I doubt it will be via AN-124s.

It will be mainly by truck using the interstate highway system or other roads where clearances have been thoroughly checked out, day or night. If need be, engines can be shipped by heavy lift aircraft, e.g., AN-124s. This was done in the early days of the GE90 production to support Boeing's 777 aircraft schedules at the time.
