Some interesting historical references for the Saturn V that launched Apollo 15, via Ed Kyle in NSF L2 Historical:
"SA-510 had improvements that increased payload by more than 4,000 pounds.
The parking orbit was lowered from 100 to 90 nautical miles.
Propellant reserves were cut and propellant loading increased.
S-II stage ullage motors were eliminated. S-IC staging retrorocket numbers were halved.
Re-orificed F-1 engines produced 7.56 million pounds of liftoff thrust.
The outboard F-1 engines burned nearer to LOX depletion, and the center engine burned longer to T+136 seconds."
Hunslet heard it was the annual wash day and had seen his friend Duck hanging on the line.
I better hide somewhere he thought. Maybe the swirly whirly machine isnt the best place Hunslet.
