The flight NE had 'most' favorable winds at CRZ FL350. Top tail winds were around 126/130mph resulting in GS of 600 to 612mph (TAS 478/IAS 280). After days of heading west, head on in to head winds of 80 to 90mph, a most welcome relief. Then issues set in: ATC directed the flight for an ILS APP into RWY 29 at KDTW. Well, after several looks at all runways I could find for KDTW, I could not find a RWY 29. I then requested an alternate RWY and APP, selecting 22L (consistent with winds). This request was granted and then enetered into the FMC. As soon as I banked to catch the localizer, 'CRASH'. This is a first for me and leaves me wondering if FS9 (and me) simply got lost with loaded flt. plans and last minute changes. Sadly, 2:10 of flight time was lost and I sit here trying to reconstruct what happened. Anyway, I thought the tail winds were most impressive and made good time northest.
