[FPSPACE] question regarding improbable event tomorrow on ISS

[Chris Jones]

I just saw a presentation on NASA-TV concerning tomorrow's internal
space-walk (I guess it's not properly called an EVA, though it *is*
being called EVA-23).  Given two space-walkers and 4 crew left inside
ISS, and given the positioning of the Soyuz spacecraft, it's necessary
to split the non-spacewalking crew into two groups to give everyone
access to a Soyuz as safety requires.  According to a slide shown during
the presentation, the plan is to have Wakata alone in Zvezda with access
to Soyuz TMA-14 (or 18S as NASA mistakenly calls it), Padalka and
Barratt space-walking in the transfer compartment on Zvezda, and
DeWinne, Thirsk, and Romanenko in Zarya or the rest of the station with
access to Soyuz TMA-15 (19S as the slide has it).  Since only one
Russian is left in the pressurized portion of ISS, it seems that in the
event of a space-walking catastrophe, a non-Russian would have to be in
the commander's seat of a Soyuz to effect an emergency reentry.  Does
anyone know if Wakata has been trained or certified to do this?  Has
*any* foreigner ever flown in a Soyuz commander's seat for a meaningful
part of a spaceflight (launch, reentry, or docking)?
