C-130 Noise?

Just chillin in Rust. Praying to god some naked caveman with a rock doesn’t club me to death when I start noticing a strange noise? Like a car engine. Then about 30 minutes later the plane flies on by. The sound stops, then 5 minutes later, it’s back. Not sure if it’s a glitch or somethin but It’s kinda obnoxious. I think it was mean’t to let players know that the plane is coming? Strange that it lasts so long. Post your ideas below!
