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.
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".
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.
I don't think that's true. As I understand it, jet engines are manufactured, sold, and maintained separately from the airframe. They're interchangeable components, and often get swapped out when they need maintenance.
What is DEI? Are they blaming pilots? Fundamental attribution error is the bread and butter of right wing nuts here (it's sometimes half their ideology, it's quite sad this is a well-known logical fallacy our 'instinct' love to make up)
