## Discrepancy

WHILE FLYING, CREW IN THE BACK ANNOUNCED THAT THEY SMELLED SMOKE.  TWO SECONDS LATER THEY ANNOUNCED THAT THEY SAW SMOKE IN THE AFT CABIN.  SHUT OFF THE AIR CONDITIONER.  INFORMED THE CREW THAT WE WOULD BE MAKING A PRECAUTIONARY LANDING.  ALREADY ON FREQUENCY WITH TOWER, TOLD THEM MAKING A PRECAUTIONARY LANDING TO THE RAMP.  SHUTDOWN & COULD NOT SMELL SMOKE ANYMORE.  NEVER SAW SMOKE, ONLY SMELLED IT.
