Space shuttle landing distance
On a test flight, during the landing of the space shuttle, the ship was 325 feet above the end of the landing strip. It then came in on a constant angle of 7.5 degrees with the landing strip. How far from the end of the landing strip did it first touch ground?

If I understood well, you only need the basics of trigonometry. You have a right-angled triangle, with the base as the distance from the end of the landing strip, the height as 325 ft and a base angle of 7.5. Use the ratio Post your answer. |

I came up with 2469 ft the acft 1st touched down from end of runway. a=325 ft B=82.5 A=7.5 b=2469 ft Not real sure about this. |

Hello rp: I don't know the answer. I know the question is bunk. Oh, I suppose one could assume that the shuttle would continue on its downward arc until it touched down... But, that isn't what it would do in the real world. If it did, it would crash and burn... What it DOES is continue on its downward arc until it's about 20 feet from the ground... Then the pilot changes the downward arc to one just below being parallel to the runway, causing the shuttle to "float" on a cushion of air for some distance before it finally touches gently down. Clearly, the landing distance is going to be a lot further than if you just did it your way... excon PS> Please, don't write any aviation books. |

Of course, it is more complicated than that in real life. The point of a problem like this is to learn basic trig. 325cot(7.5)=2468.62 rpmacs, you are correct. |

Curious to know this. It's typical orbit is around 200-250 miles above the earth's surface, although it will be going higher when it services Hubble. But does anyone know what is the limit for how high the Space Shuttle can orbit the earth? Thanks!
I am looking for a movie that had a boy who stole a space shuttle. It looked for like a flying disk. The ship would talk to the boy. The boy could talk to a glob in the ship. I only remember little things about the movie. Like the boys brother shot fire works in the air to show the boy and ship...
Once again we are faced with tile damage that could put this mission in jeopardy. We know that the tiles are fragile, and easily damaged. Why not install a thin carbon fiber (or some other suitable material) sheet over the bottom of the shuttle, to protect the tiles from harm during lift-off?...
