Why Space Shuttle doesn take-off like the Aeroplane, to save the fuel?
Taking off like an aeroplane means that you are taking a smaller angle out of the atmosphere, therefore you are constricted to gravity longer and it takes more force to break through. The force you would need to both push the weight of the shuttle upwards as well as forwards AND break through the atmosphere would be immense and it would take much more fuel. Plus, its not very safe hunking round a very unstable shuttle and huge canister of explosive material above a country for a long time, and this could turn bad in the testing area of implementing the idea.
