In a traditional airplane all of the lift is supplied by the wings but as speed increases this puts more and more stress on the wings the answer as was determined years ago is to use a lifting body . That is a plane or as in this case a space shuttle that maximizes the strength of structure by using the body of the shuttle itself as the wings. It has not been used heavily in the aviation world due to politics but it was the only chance for a ship that needed to re-enter an atmosphere from orbit. Unfortunately a true lifting body would by its nature be very stable as it comes down but not very manoeuvrable at high speed. NASA solved this problem but using a large rudder fin atop the vehicle this stabilized the side to side motion making it as stable as the forwards and up and down motions. The only other problem was to find a long enough strip to land the shuttle because of the forward speed required to keep it aloft. The space Shuttle was the end of a long line of expert-iments in this type of flight. For those who have seen the old TV series the Six Million Dollar Man the scene in the beginning was a real crash of one of the early lifting bodies designed by NASA they were flown up by airplane and then dropped our current Mountain fold the middle and valley fold the 2 sides. then turn 90 degrees to the right. space shuttle design was the winner. PVB Fold the flap on each side into a rabbit s ear that points to the back of the model. The first crease in step 1 is the front. Valley fold the left side down along the line of the rabbits ear created in step 5. Then valley fold up the flap even with the bottom of the model then unfold back to the diagram at Using the creases just made crimp fold the tail section into place. step 6. Valley fold the right flap to the left along the crease made in step 2. Valley fold the front over using the raw edge of the previous .
