Hi HZ. Fully aware of B744F program of GSS.
This was in AirCargo publications and "Cargo Facts" newsbulletin issued on Friday. I somehow feel this is "old news" as the co-operation with DHL has been there for sometime but articles read as if they are taking their own aircraft, i.e for bespoke use.
Nothing to stop them selling to GSAs etc to fill up remaining capacity.
