1969 they went to moon all with 1960s tech yet they or anyone else even with todays tech can get a human 400 miles up, thats technology going backwards. The onboard computer that got them there was way less powerfull than a 48k Spectrum ,remember those?... and dont even mention that lunar lander. They did it though,first attempt.Neil Armstrong landed that lander in a vacuum on a moving moon with no practise of landing in a vacuum but he did it though first attempt. All 3 made it back safely as well,even when exposed to high radiation levels. Dont believe me? Well its true because i saw it on TV.
