Found some good footage of a J57-powered KC-135A I thought would be good to share on here:
I remember threads on here stating that the original KC-135A's powered by J57 turbojets with water injection were among the loudest aircraft ever used by the military. I doubt water injection is being used in this video, but they're still loud and smoky! Fantastic sounding aircraft; really they don't sound much different than JT3D's/TF33's, especially when landing.
Also some footage of a CFM-powered KC-135R.
