Interesting situation at WGN today (2/6/22).

One MD11 is flying a revenue mission. The rest are on the ground at SHV or RSW (their maintenance locations), except for 2 that are apparently not-flyable, one at ICN and one at ANC (after #3 engine failure in climb), and one that is in heavy-check at TPE. So all the flyable MD11s but one have returned to either SHV or RSW.

Something up? An AD? Something to do with the FAA? To have 11/12ths of the MD11 fleet (not counting 435KD and 804SN, which have been grounded for years) not operating is certainly an attention-getter, particularly in this high-revenue international cargo environment. I saw where National's chief said the other day that he could fill 10 more 747s than he has.
