A few months ago I was on a NW DC-9-30 from SAT-MEM. Anyway, I was in first class and sometime before pushback there was this noise like an electric drill that sounded like it was coming from the floor... Any idea what it was?

Did you hear it before engine start? And did it go away after the engines were running?
