I think root problem is that shuttle was starting and landing with people. They should use it just for cargo, second rocket with Apollo should have transport people from/to orbit.
- bdunbar 13y agoWings were the real problem. They stuck out where they could be struck by stuff. They precluded the capsule eject system. They cost Shuttle tons of fuel. For a system used in only one part it's flight regime. Why _why_ did Shuttle have wings? The Air Force insisted. So they could launch Shuttle into polar orbit from Vandenberg. Shuttle would need the wings to come _back_ to Vandenberg. Then the Air Force withdrew from the program. Too late to get rid of the terrible wings, however.
- gaius 13y agoCurious, how would it land anywhere without wings? Apart from splashing down.

- InclinedPlane 13y agoYou don't need huge delta wings to land, a lifting body design with maybe little wing stubs (like HL-20/Dream Chaser/BOR-4 works just fine). Here's an M2-F3 landing video, as an example: http://www.youtube.com/watch?v=iaz6Bmitawo http://www.youtube.com/watch?v=iaz6Bmitawo
- deletes 13y agoElon musk explained many times how Dragon will land with helicopter precision. Currently it lands with precision of a few kilometers( because of the wind, they use parachutes ). They can do that because even on a symetrical capsule you can have lift vector control. I can't find the video, but you can look it up with google. It is very easy to find.
- bdunbar 13y agoWhat InclinedPlane said. The huge-giant wings were needed so Shuttle could fly cross-range back to Vandenberg after going over the pole.
- curtis 13y agoIt's a legitimate question to ask if the wings were worth the trouble. However, the real problem from a safety standpoint was that Shuttle was riding on the side of the stack rather than on top.
- Already__Taken 13y agoBecause it had wings. You can't put wings up top without even bigger wings down low to make the thing stable.
- curtis 13y agoEven if that's the case, those lower wings aren't as vulnerable to minor damage since you don't need them for re-entry. That said, I am firmly in the "wings aren't worth it" camp anyway. Just put a capsule on top.
