can't find the chec in the rr Sta

[6ftdwarf]

I can't find any other germans to kill, i captured the mechanic, swithched clothes and still can't open any of the doors.  I figure he's upstairs in the middle room but can't get it open in time.  I'm only playing in easy mode, single player. What am I missing?
