UAL want's its airplane back and its customers safely delivered to their destination and both UAL and the regulatory authorities give captains the sole authority in matters of command once out of the chocks, in order to achieve those objectives. This captain safely delivered both the aircraft and its passengers to their destination, albiet after exercising his sole authority to include a short diversion to MIA. The question now for UAL and perhaps also the FAA, is whether the captain will ever get the opportunity to exercise that authority again.
