I recollect that the Channel Airways operation to which you refer was called 'The Scottish Flyer' and this was painted on the fuselage where one would expect 'Channel' to be.
I thought that it originated at Sarfend and could not imagine that even Channel would operate Viscounts out of Portsmouth which was grass, was it not?
Certainly, a couple of (Channel?) 748s went off the end on one single wet day there!
Could be wrong, though!
