Well done to the FEDEX pilots!
What a shame that the United DC-10 accident happened years ago with many deaths in order for McDonald Douglas to separate the hydraulic lines near the #2 engine (including a fluid shutoff valve?), so that no more planes could lose all hydraulics at the same time due to a turbine or compressor blade(s) burst.
FAA aircraft certification often "works" in very mysterious ways.
Remember the Swearingen Metroliner (stretched Merlin, known as the San Antonio "sewer pipe") turboprop with Garrett engines, which had a very small rocket in the tail cone, in order to boost the climb rate during an engine failure at takeoff? And this was only under Part 135: NO 2.4% second segment climb gradient was required.
