GSS contract with BA terminated
As popgun said.
However it may still be prudent for Atlas to have use of a UK AOC should a suitable contract come along, even for just one aircraft whether it be a -400 or a -8.
I believe two of the GSS -8s are going to LUX for bridging checks before returning to Atlas and the other HKG. I don't think Atlas have found work for all 3 of them yet. With the military flying slowing down it will be hard to put these three airframes in a contract flying the same kind of block hours that they are currently flying with GSS.
