The introduction of turbofans and high bypass ratio engines has made those old jets sound like dinosaurs.

Those fully loaded flying gas tanks had those 4 engines pinned on takeoff So it must have sounded like few other things.

During the time I was in the early '90's they started retrofitting 135 tankers with F108 (CFM56) turbofan engines that greatly reduced engine ground clearance but were better than the J57 in all other categories.
