Narrative:
We pushed back from the gate and during engine start another aircraft which was a B737-900 also was pushing back in front of us. We happened to look up only to see the aircraft continuing to push fairly close. Our marshaller had to move because of jetblast and the other aircraft continued to push. The 900 only stopped when the tug driver noticed our marshaller running from behind the 900 aircraft. Only then did the tug driver look and notice us. He stopped the push and pulled the aircraft up away from the nose of our MD80. The 900 tail was between 16-20 ft away from the nose of our aircraft. What I do know is the push would not have stopped had our marshaller not come running out from back of the 900 in view of the tug driver. Oh; by the way; the 900 did not have 2 wing walkers. They had a tug driver and a person walking alongside the tug with a headset. No other personnel were present.
