Very sad indeed. FYI United States FAA SFP ( Ferry Permit ) for aircraft that size not on FAA121 AOC/Ops specs. Essential crew only ( 3 max ) plus mechanic all must hold FAA license, this old machine seems was a straight out ferry candidate only. Read she was carrying 19 pax and gear maybe 2000kg I guess to much at her age at 5700 foot field elevation. I hope all are recovering quickly, looks like crew did the best with what they were given.
