From memory the previously excellent British Airways Engine Overhaull unit located at Treforest in Wales was handed over to General Electric as part of the deal that GE
engines were supplied with BA
's initial 777 aircraft.
Subsequently there were some horrendous stories emanating from the unit - some of which reached the media, but there were are number which did not!
Per Ardua ad Astra! ........ Honi Soit Qui Mal y Pense!
