I was down in SAT this past weekend, my first trip to the airport there, and I was surprised to see the extensive maintenance facilities that they have. One of the aircraft that was there was particularly surprising, a Saudi Arabian MD-11 was parked out west of the passenger terminals outside of a hanger. Does anyone have any idea what it is doing there? I realize that routine maintenance is a likely possibility, but I was surprised that it would be flown so far for that reason (even though I know that it happens a bit). Does anyone know if it is being sold? Or perhaps converted to a freighter? Do they have that capability in SAT? Most of the pictures of Saudi Arabian MD-11s on this site are of freighters. However, there were windows and no cargo markings on the aircraft. Anyone know? Thanks.
