Not necessarily a radio transmission, but sitting in back of a Shuttle flight ATL-IND last night when this came over the PA from the flight crew, "From our cruising altitude of 14,000............" Myself and a NetJets guy I was sitting with are both thinking the same thing.... What's going on here? He later found out both packs were deferred, Yippee!!! Least we lucked out and had smooth air for most the flight, couldn't imagine the fuel burn on that segment.
