In order to keep down the drag, some of the turbine stages could be removed(this was back in the earlier years). With yaw trim adjustments and fuel management, the effect of the fifth engine could be minimized. I do not know if the Air India plane was carrying a spare, or if airlines carried spares while carrying passengers. Peter Barada {ihnp4!inmet|{harvard|cca}!ima}!pbear!peterb
