Welcome to the News community!
Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link.

For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

Was it just surging or like a compressor stall or something? FOD like a bird ingestion or something?
I mean, Boeing has/had quality problems, serious ethical failures, but also birds exist.
(I’m not good at explaining this, maybe should have found an explanation online somewhere instead.) You know those stages of a combustion engine - intake, compression, ignition, exhaust, all happening in sequence in an engine’s cylinders? Turbine engines do them too, but in a straight line and constantly. The front of the engine is obviously intake, but compressor fans do the compression just using fast and powerful fans, no seals or valves needed. Ignition lights everything up, exhaust can just flow out the back. (It flows over some more fan blades that steal some power from the expanding gases and use it to keep the whole thing spinning.)
Unless something goes wrong with the compressor fan blades, that is. If compression is too weak and the ignited air/fuel mixture can flow back out the front of the engine, that’s bad. And yeah, it happens sometimes, with any engine. Almost never with both at the same time. (Both engines failing at once low to the ground is like a once in a generation thing, and yeah it’s really really bad. And really really rare.)
Lotta people on the internet who would disagree with that one buddy
I'm sure an engine would have just as tough of a time with a spy drone as with a hypothetical flying animal XD
I have seen news stories describe engine surges as "bursting into flames" before, but that's not the case here.
The video of the incident shows a small but sustained flame emerging from the bottom-rear of the engine, well below the engine's core.
There was an engine fire but in typical journalistic fashion it was far short of bursting into flames.
Unlikely to be boeing's fault as they don't make the engines, just the airframes.
Edit: An engine surge/compressor stall is the plane's version of a backfire. Big bang and a burst of flames. Very exciting, but very little danger beyond the loss of thrust. This incident wasn't a surge, but the last time I saw mainstream news say an engine "burst into flames" it was.
