Narrative:

At top of climb lost #1 hydraulic system. Dumped to 440000 pounds routine. Callback conversation with reporter revealed the following information: reporter captain believes the hydraulic system loss was found to be caused by a leak in the upper rudder or upper stabilizer. Reporter says he could have continued with the other hydraulic system operating normally, but the flight crew had a long day and were fatigued. That, with the possibility of other problems compounding that hydraulic problem, the captain elected to return and land.
