Their initial PROBLEM was possibly an indication issue. They were not even committed to return and land. They investigated, remaining close to the airport in case things went worse rapidly, found they had more issues, worked on extending the gear, did a fly by inspection, and found they DID have a major problem, and announced an emergency. They added " Roll the equipment" in plenty of time for the equipment to deploy to the best location on the field for the type of emergency that they had.
In the course of the flying around and attempting to correct the PROBLEM, they burned about half their fuel, and landed with "3 souls on board, and one hour of fuel" The on airport fire equipment was well prepared for the event, and there were no unexpected issues.
And no packages were lost or destroyed. I personally believe when the final report comes out, they will look pretty good, even though the ruined a pair of engines and may have converted an airframe into spare parts. Some in the industry claim that the engines keeping most of the belly off the pavement can mean that a reskin of the aft belly similar to a sever tail strike, may return this airframe to service.
I am inclined to say "Well Done" to these pilots
