So whats these orange portacabins some have said are they EZY or Oasis?
As I dont live close enough to see for myself, but I am reasonably confident that the portacabins would not be for OASiS's use James.
They only use MSE for it's runway during their base training flights, and on the very rare occasions when they have to do a full-stop landing, the crew usually go to the terminal building.
