- Again, I think I see were we are differing. See my other

- True... but astronauts have "Pigs in Space" to worry about.
- A diver can swim back. Or, with enough air (which they should
- always have) resurface. Astronauts are a bit more restricted.
-
- BTW, as an aside, I seem to recall 1 mile or so as being a
- useful limit for eyeball maneuvering in space. (i.e. you don't have
- to worry about changing orbits trying to catch up to something,
- you can jsut fly in a straight line.) Is this right?

- Because I wasn't aware that DC-1 would have docking
