Seriously though, SpaceX isn't Usain Bolt, it's... Fabio Cerruti (of Italy, fifth-place getter in the first heat of the men's 100m at the 2008 Olympics). He ran 100m in 10.49 seconds, which is very impressive, but nothing that hasn't been done before.
Sorry if it wasn't clear. To my understanding, "pushing the envelope" means just going a little bit further than anyone else has gone before. You obviously have a different definition.

OK, enough athletics analogies.
