If you guys can not handle another opinion based on reporting from one of the flight crew (Y O Y)
From YOY: I Think The Crew Handled It Well.... There Was A TRE On Board As Well
If YOY was one of the flight crew then he would know that the person onboard was not a TRE but a Nominated Commander and probably the worst one we have. Thankfully the Captain under check knew what he was doing.
