Narrative:

Had to shut down #2 engine due to loss of oil quantity and oil pressure. Deviated off 'T' track to execute drift- down procedure. We broadcast over 121.5 that we were deviating 30 mi parallel course and descending to FL250 which was our 2-ENG altitude. ATC and company dispatch was advised. After reaching FL250 we were cleared back on track 'T' and cleared as requested to nearest suitable airport, glasgow. Our original destination was amsterdam.
