Unexpected arrival at Manchester at 12:40 on 27 August 2007 was Alenia C-27J, I-EASA, showing 'M.S.N.126' on the rear fuselage. It is reported to have diverted en-route the United States with a pressursation problem, that was seemingly soon fixed, as it departed at 14:05.
This aircraft, c/n 4126, was intended for the Greek Air Force, but has apparently been diverted to the JCA (Joint Cargo Aircraft) test bed programme across the pond.
