- You can walk from one place to another carrying a four-ton

-
- About as careful as divers probably were when logging
- the first hundred man-hours on the first aqualungs.
-
- Ever note how many recreational divers there are today?

-
- Divers can drift off, too. And they have to worry
- a *lot* more about sharks. :-)
-
- The difference is, we've spent, probably, millions
- of hours perfecting SCUBA techniques and hundreds
- of hours on EVA.

-
- So why do you assume that anyone who does inspace refueling
- will try to do it "under weigh" instead of docking first?
-
- Oh, I forgot, we're assuming that the pilots are stupid. :-)

-
- And the C-130's design didn't include cabbages. That doesn't
- mean that if you needed cabbages someplace, you couldn't use
- the Herky bird to haul 'em there.
-
- Cargo planes are versatile.

-
- What makes you think a DC-1 can't accomplish a hard docking.
-
- McDAC has artist's conceptions showing a DC-1 docked to
- space station Freedom. That should tell you something.

- No, we're being misquoted. What we actually said was, "Lead,
