I'm new to this community and was curious to ask something without doing the math myself to even get a sense for how reasonable the question is :P.
Has any hobbyist group (perhaps even a very large and established group) ever managed to launch a rocket and/or its payload into low earth orbit? or more impressively has any group managed to have a rocket escape earth orbit?
The most impressive height I've seen recently was a video from a European group (teaming of a school in Germany and Sweden I believe?) that launched the Rexus 9 rocket to ~80km.
