I know Evergreen and ANA have also had an engines come off in flight from 747s.
You might want to balance your post by also mentioning the 747 in the early 70's that took off on the wrong runway in San Fransico, and the lighting gear at the end of the runway tore out the belly of the plane. They lost three out of the four hydraulic systems but still managed to make an otherwise safe landing, even with massive damage to the structure.
And the China Airlines 747-SP, that lost an engine on the Pacific then stalled & flipped over onto it's back. On the pull-up it went to 4.7 G's and 5.1 G's, or something like 200% of the designe loading, yet it managed to stay flying.
Also, the engines seperating from the structure is pretty much what they're designed to do in certain cases. So some of those accidents protrayed had the design of the craft doing what it was supposed to do.
But true enough they have had some odd failures from time to time.
