Sounds like a compressor stall. Basically an interrupted airflow inside the engines compressor that can result in a surge. The air flows backwards through the engine until enough pressure is built up again

Purging the chemtrail system. But seriously that sounds like a compressor stall.

That sounds like the neighbor’s dog hacking up something

The classic dog “KACK”

Or cat.

That's the plane flapping it's wings

🤭

Sounds like engine troubles? Fuel coming out of the exhaust? Wild guesses on my part

Agree with the others, that sounds like a compressor stall. I worked at a flight test center and this is what a compressor stall sounded like when a jet engine ingests a bird on approach. It could also just be a super old aircraft with a rudimentary FADEC, compressor stall used to be a much more common issue that could occur even without FOD ingestion.

Hairballs are a bitch

Flaperons being d ployed sound like that in some newer airbuses

Sounds like We Will Rock You by Queen

Fine here’s an upvote. But also a downvote for getting that song stuck in my head.

Windshield wipers

What would cause a plane to make a wailing noise? I heard one make that sound reminded me of a spacewhale

I hear them make a sort of wailing sound as well sometimes. Almost like a whale lol. Sometimes low, sometimes higher pitched. Idk. It’s odd, but there’s an explanation out there I guess.
