This VTOL test vehicle was based on the British 'flying bedstead' used to develop the Harrier eventually.Lastly, here's a video showing how cool Neil Armstrong was under pressure:

The loss of control was because the computer system was not capable of full autonomous flight at the time.
Neil Armstrong had fast reflexes which he used to eject as the platform passed the safe angle of flight.
I do not think this required much spatial awareness.
