last 100 yrs since we invent flying, we did'nt develop much, u think that we will travel into deep space?

You consider the change from Kitty Hawk to the space shuttle 'not developing much'? What exactly do you expect?

We do travel into space. Satellites are launced all the time.

Aircraft and space craft work on totally different principles. Space flight didn't start until 50 years ago. But the progress does seem frustratingly slow, doesn't it?

the problem lies more in the fact that humans need oxygen, food and water to survive and there is so far no cost effective way of sending humans into deep space. The International space station needs to be restocked, thats why they are up there for long periods of time

We havent come far though? Have you seen a B2 bomber or even a 747 take off?

Of course we will. No doubt at all about it.

Doug

Yes.

Yes. We will conquer the mystery of time and distance, and eventually go into deep space. The only thing holding us back is ourselves.

the last 100 years have had more iventions and innovations than any other century in history, with maybe an exception for the industrial revolution. we went from a flight 6 feet off the ground, to sending people into space. we have planes that can fly around the world nonstop. flights powered by propeller and prop, to jet engines. breaking the sound barrier, Supersonic Transport planes (the concorde), and most recenlty, commercial flight into space will soon be reality..

and we would already be in deep space if it wasnt for the dark and middle ages. basically 800 years of fighting and science being considered "evil". what a waste that was.

No, humans will never leave this solar system.

Didn't develop much?? It took modern humans 100,000 years to develop rudimentary powered flight, and then just another 66 years to land on the moon. You could've have been a kid hanging out on the sands of Kitty Hawk watching the Wrights, and then lived to be a retiree watching the moon landing on TV.

Compare the original Wright Flyer to the B2 Stealth Bomber, the 747, the Space Shuttle, the Hubble Telescope (not to mention nonflying things like the microprocessor and the Internet). If you think there wasn't much development, you need to quit smoking crack.
