Could you please tell me where you found this information? Samoa Airways' website is still up and they seem to be active online. As for TACV, they rebranded in 2018 as Cabo Verde Airlines, so they are still the flag carrier for Cape Verde, but under a different name.
Suggest you allow people to enter variations on spelling, particularly as you have some wrong. For instance it is either SAS or Scandinavian Airlines not combined as you have shown. Also it is EuroAtlantic Airways not Atlantic Airways
Otherwise, had fun with this tough one.
