- See *2010*. The first cosmonaut across uses an MMU. She brings a
- rope with her. Subsequent transfers are straightforward (if the
- engineers have done their jobs on handling of this tethered system!).
-
- Crew transfers between aircraft in flight have been done. See the
- career of Ormer Locklear, the greatest wingwalker of all time. I
- believe the first aerial refueling (and if this story is not true, it
- damn well *ought* to be) was accomplished when a wingwalker strapped a
- jerrycan to his back and climbed from one DH-4 to another. (DH-4s are
- another proud product of the Canadian Aerospace Industry.)
-
- Given proper equipment and training in both cases, an in-space
- transfer or refueling operation *is* less dangerous than the
- equivalent in mid-air.

- Right.
