Correct, as from Monday there will no longer be an RAF airfield at St Mawgan. However, the domestic site remains and that is still known as RAF St Mawgan. Purely pedantic I know, but true!
The MATZ has not gone, for a couple of days anyway, and you can get fuel, you just have to go north side to the civilian terminal, and there never was a feeder! More pedantry!
One of the RAFs best bases in my opinion, and I am sorry to see it go.
