I have to call BS on this one. The author obviously is pro-American manufacturing and is just trying to use this to sway opinion.

A. Those aren't seat-belts, they are cargo straps. Those are like 10+ feet long... who has 10 foot white seat belts? And someone who can't spot cargo straps is going to explain what an turbo-jet fan blade is supposed to look like

The author goes on to use the airport code (FRA) to refer to an international airport. Seems like an attempt to make it sound more real. (known as useless details when detecting a fabrication)

A 4 engine airplane is not certified to take off with 3 engines while passengers are aboard. It is only certified to do so for "ferry flights". (aka taking the plane back for repair... empty) It takes a fair amount of extra skill to do and is usually handled by special pilots working for the manufacturer with the right training. Pilots have a really strong desire to live like the rest of us.

This is very likely a photo taken of an engine from an investigation of an airline accident after it ate crash debris in the final few rotations of it's life. That engine wouldn't have merely "vibrated"... it would have disintegrated had it been in use. Esp. with the split connector ring in the bottom center.

The last line is the sinker... shows the authors true intent. Even if it was true... what does a poorly maintained aircraft engine (probably built in Europe or the US) have to do with a car built in China?

Sorry Fossil.. had to comment
