Narrative:

Normal operation until takeoff. We heard a muffled sound -- like a pop. Shortly after that, captain reported a problem -- it was sensor or valve pressure (I don't recall) and said we would be landing back in mia in 10(?) mins. We were not asked to do a planned emergency, and landing was uneventful. We stayed with the passenger until the problem was fixed -- about 40 mins. No further incidence. We took the same plane to sju. Problem corrected by maintenance. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a B727-200 and had a full passenger load. The reporter said the cause of the return to the field was unknown as neither the flight crew nor maintenance shared this information with the cabin crew.
