Going to Area 51

watch this video


in it the govnment clearly states that in 1958 we had nuclear rocket engine technology and by 1970 we were to be using it to fly USA persons to Mars and beyond.
Well, we are not doing that, so what happened?
The aliens quit cooperating, early on they were friendly and helpful, but after 10 years or so at Area 51, they figured out that the govnment was not going to let them freely R&R here on earth. So they quit helping. The evidence is in this video, The USA has done many great things in space, but to date it has all been using the chemical rocket technology that existed prior to the aliens landing at Roswell. There was much progress from 1948 to 1958, but since then no quantum leaps in rocket technology.
Sixty years have passed and now the Ruskie's are trying to figure out Nuclear Rocket Technology. In the video NASA/AEC (the Govnment) says we had that in 1958.
