	Boeing realized that transportation of spare engines was a high
shipping cost, so they beefed up the midpoint on the left(right)? wing
between each of the engin pylons that allowed the mounting of a fifth engine
that would freewheel. 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.
