- You're being led astray by words.
-
- Both airplanes and orbiting spacecraft are said to be
- "in flight." That doesn't mean they have anything in
- common, except that neither one is in contact with the
- Earth. We also say that ships and islands are "at sea."
- That doesn't mean that ships and islands have very much
- in common.
-
- An orbiting spacecraft is not flying like an airplane.
- There is no air rushing past the wings. It isn't using
- aerodynamics to stay up and isn't using its engines to
- maintain velocity. If it runs out of fuel, it does not
- come crashing back to Earth like an airplane.
-
- When two spacecraft touch each other, they are not "in
- flight" relative to one another. They are said to be
- "docked," like ships at sea. So, if you want to base
- your analogies on words like this, you should argue that
- the US Navy is the only organization that can navigate
- two ships to the same dock, then transfer fuel from one
- to another.

-
- We aren't talking air-to-air refueling either. In-space refueling
- does not require split-second timing, only hooking up the hoses
- properly.
-
- So, what's so special about the ground?

-
- Again, I thought that was what we are doing.
-
- What are *you* doing, except standing on the sidelines carping?
