I’ve always heard that the J-79 was exceedingly loud.
The F-104 Starfighter had just one, and it was loud as hell. Sounded like the mother of all vacuum cleaners, attached to a moose in heat with a megaphone.
The F4 had two J-79s. It must have sounded like the crack of doom.
I’m too young to have experienced either one personally.
Although I have it on good authority that the sound that Johnny Quest’s dad’s jet made was actually a that of Starfighter at idle speed. Basically the coolest turbine whine you can imagine.
It did. Growing up I spent time living on a base were some were stationed. Our house was no where near the flightline but you still had to stop your conversation and wait for them to finish taking off. Loud.
