Well, except for the two SRB's that are required to get it off the ground...every Shuttle launch,
And your point is? Some how I fail to understand how the fact that these rockets used more than one fuel helps your argument any, especially since they were not hyperbolic.
Can and should are two very different concepts. Sure launching a rocket on hyperbolics is possible, but is it wise or economic? What has been left out of this conversation is the nature of hyperbolics themselves. Hyperbolic fuels are deadly poisonous in the few parts per million. Its poisonous nature has two effects. One is makes it more expensive than other fuels to produce, transport, and store. Two it make using large amounts of it as a fuel within the atmosphere a very bad idea.
