After abandoning his taxi in one of the aforementioned zones (and leaving the meter running with a passenger inside), Ted manages to find Elaine inside the airport.
We find out that the two once had a romantic relationship, but that it's since failed. It's clear that Ted wants her back, that he can change, but Elaine explains that her patience has run out. It's over.
Elaine heads to the plane, leaving a frustrated Ted who proceeds to break the fourth wall and address the audience directly, an example of the self-aware, meta-humor that characterizes Airplane!
Captain Clarence Oveur, the pilot of the eponymous airplane, receives a call from a doctor at the famous Mayo Clinic explaining that there's an important medical patient, a sick little girl, who will be transported on Oveur's flight then taken to the clinic in Minnesota. She'll be having a heart transplant and must be monitored closely. (Note the set decoration at the Mayo Clinic.)
After the sick girl is delivered to the plane by ambulance, we cut to Elaine and Ted who are at it again.
We learn that Ted's a former fighter pilot who can't bring himself to fly again after trauma experienced in an unnamed war.
Elaine insists that he must accept real responsibility, and explains that she has to move on with her life.
