Is it really reasonable to think the astronauts would have disobeyed orders and landed on the moon? This seems like it would have so many negative repercussions on the astronauts involved that it seems outside the realm of possibility to me.
Also, disobeying orders in space has happened before: https://en.wikipedia.org/wiki/Skylab_controversy
"[T]he crew were alleged to have stopped working. Gibson spent his day on Skylab's solar console, while Carr and Pogue spent their time in the wardroom looking out at the window."
