Air Canada's Boeing 777 trails flames on take-off

Ranting about this on the porch, the boy interrupted me and said "yeah, yeah, it's like peasants seeing a comet in the middle ages, it changes everything".

To be fair, that's an engine problem and they aren't made by Boeing.

Knowing Boeing, they probably installed them wrong, broke them, left a tool inside, etc.

Boeing contracts them, so Boeing is ultimately responsible, of course.

These days engines are usually leased separately from their planes and the leasing company provides maintenance, repair, and overhaul with their own MRO provider or a third party of their choice. Boeing wouldn't be involved.

That's not really a funny or helpful comment generally, but especially not since the plane in question (C-FIUV) is over 16 years old...

Kinda weird that it took 30 years for someone to notice the engine was backwards, no?

Looks like a compressor stall/engine surge, where the airflow suddenly reverses and causes a shockwave. It can damage the engine pretty severely especially if it happens multiple times or for a longer duration. Often reducing thrust helps (though this is of course a compromising thing to do during takeoff)

It's not supposed to happen under normal circumstances and clearly it happened several times in a row here. Maybe some blade damage? Anyway I'm sure the investigation will turn up the cause.

I'm glad those people are ok. Though it isn't normally immediately dangerous on modern engines (e.g. it might lead to loss of thrust but not resulting in an explosion). That did happen on older engines though. I'm sure it must be scary, seeing flames and hearing bangs.
