Narrative:
I was towing a banner over [the stadium]. I was training a new banner tow pilot in the process. We were at 1000 MSL with a heavy banner in tow. The cessna 172 was towing at about 25 inches mp. I then look down and see the cabin filling with white smoke. I immediately declare an emergency on tower frequency. I then turn to the football practice field as an emergency landing field. Then I turned off the master switch and that caused the smoke to stop. Then I decided to go to the airport to land. Upon landing I secured the airplane and looked for a sign of fire but could not locate the source.
