lear60fellow,
Don't think it was mentioned anywhere COMPLETE hydraulic failure, merely 1 (of 3 ), systems. Oh, and I think it was 30min after dep, not 1hr.
As I have said ( & you should also respect, I would humbly suggest) without a detailed knowledge of the 767 systems , it would be foolish to publicly applaud/nor castigate the crew at this stage, other than saying, damned fine landing ! !
