It’s LC-39A, pad camera E-8.

Soon as I saw the title card I could stop playing, I’ve watched and rewatched this footage so much i can play it back in my mind. If you haven’t seen it and you love rockets, this is a must watch, the F-1 engine in all its glory. The details are clear enough you can clearly see the turbopump exhaust stream flow interacting with the rest of the combustion chamber “rocket exhaust”.

It goves me an appreciation for the energy required to lift something heavy out of Earth’s gravity, as well as the expense. It makes missions to Mars, or even economical asteroid mining seem further and further away.
