Lot of info in the /r/Aviation megathread here:
Apparently the #1 engine fell off the airplane completely on the takeoff roll. Also heard from a buddy at UPS that they were on a 2 hour maintenance delay for the #1 engine before they left.
that would explain why the flames on the wing were so massive - not engine on fire, the fuel just gushing out of the wing, wonder what that does for systemwide fuel pressure
Headed to Honolulu, so massive amount of fuel onboard.
MD-11s have a recurring issue with known, unknown problems. Phantom electrical stuff that comes and goes. They throw what parts they can at it until it powers up and send it, they have done this for a very long time. Lots of parts cannot be sourced, most is "refurbed" stuff that is not ever up to OEM spec - which wasn't great to begin with.
