Reusable Space Craft

Everything that is sub-orbital or beyond.

I have thought about this for years. I have no formal education just a love for space. So here it goes, if we can build aircraft like the SR-71 and the U2, that can reach the uper reaches of the atmosphere. Why cant we build a reusable craft capable of reaching the upper reaches of the atmosphere under conventual power with detachable srbs to reach orbit. Then return to earth like the shuttle?

In a nutshell: Gravity. To escape gravity you need speed. To reach the speed, you need lots of fuel. Fuel takes up a lot of space and weight.
And let's get one thing straight. There's a big difference between a pilot and an aviator. One is a technician; the other is an artist in love with flight. — E. B. Jeppesen

Thats why you use srbs. They don't require a tank or gallons and gallons of fuel.everything is inside the booster that can be jettisoned. So I still don't understand why this could not be possible!

So you mean you would carry the SRBs up to high altitude, then light them and go into space?

That would require a HUGE amount of fuel to get that massive weight up to high altitude.

I might be wrong but ram jet engines require less fuel than a turbine engine. Yes I know there would be limitations and problems. But it could work if jet technology improves. Keep in mind at a higher altitude you wouldn't need srbs as large as the shuttle. You wouldn't need as much energy to leave the atmosphere, because your not launching from the ground. The srbs could be considerably smaller
