Freightdoggy:
WAS do indeed operate a couple or 5 ATPs for the Swedish mail service. They have initiated and are in the process of STC'ing a large cargo door conversion. Once the conversion is completed there are rumours that they will be chartered by DHL to replace the 748s.
WAS is a nice little outfit located in the middle of nowhere in Sweden. Nice people, good organistation, long term mail contracts, ad-hoc work around Europe and a few contracts with DHL too.
