Mission control deliberated quite a bit on each burn before instructing the astronauts on how to execute it.

Although this was an emergency, they had a lot more time to navigate than they would in a liftoff from Earth.

This NASA's source gives a good overview of what was required. They executed several burns of the lunar module's engine in order to return to Earth, according to instructions from mission control and using the Earth and celestial bodies out of the window for reference. When the service module failed, the astronauts were forced to abandon their descent to the Moon's surface and instead use the lunar module as a lifeboat.

More spectacular manual piloting occurred during the Apollo 13 lunar mission, including changing the orbit. More information about that can be found in this Wikipedia article about space rendezvous. Manual orbital rendezvous has been tried, and the first attempt failed due too poor understanding of orbital mechanics. If you are going to provide a guidance system, you may as well link it directly to the engine rather than having an unnecessary step of using the pilot. Such an orbit would be a waste of propellant. Without significant guidance, a pilot would not have the precision to enter such an orbit, so would need to overshoot, putting the spacecraft into a higher (or more likely, elliptical) orbit as this would be a safer option than undershooting and ending up entering the atmosphere and crashing in an undetermined part of the world. Most rockets go into a low Earth parking orbit initially, and this barely skims the Earth's atmosphere. High G forces would make the rocket difficult to control.

It is essential to get up to orbital velocity as quick as possible, because at low speeds you waste propellant fighting gravity. I believe manually flying a rocket to Earth orbit from Earth's surface would be impractical for the following reasons:Īll current rockets pull massive G forces in the early stages of ascent.
