The F-4 Phantom: proof that if given enough thrust, you can get a brick to fly.
*******************************
I served on a carrier in the early ‘60s; catapults division. I can attest that the F-4H aircraft had VERY powerful and loud engines. .....Too bad that they didn’t have cannons or machine guns. Having only bombs or missiles led to many being shot down over VN later. ....The sweep wing version may have allowed some to evade enemy aircraft more easily.
I was in Civil Air Patrol as a kid. lots of the local meetings/gatherings of squadrons took place at Selfridge ANGB. I saw and heard a lot of them as a teenager. And you’re right, they are LOUD!
