Along with their operations from somewhat-remote Southend and Stansted, Channel started up a quite substantial road coach operation, based in Southend, to take passengers to and from London, where they had the "Channel Coach Terminal", which appears to have been a bus stop pole in a back street near Kings Cross station, an interesting place to start your holiday from. When they went under in early 1972 the coach operation, which had picked up various other contract work along the way, was sold to its management and kept going, as Channel Coachways, still with black and gold livery (maybe they had picked up the airline habit of never repainting anything). Part of the dowry from the receiver was the vehicle decals, with Channel Coachways in the font of Continental Airlines that came with the Viscount 800 fleet purchase, and the oval eagle logo from the same source. They carried on like this for quite a while, unconnected with aviation. I last saw one of their vehicles on the road in London in the mid-1980s, still with the same badging, and a huge oval eagle on the side, which looked for all the world as if it had originated in the Continental Viscount stores, as it was the size of their nose decals !
It's a bit challenging now to find evidence of all this, but here is an old photo of some new-1967 road coaches of theirs, in the Southend airport car park, with a recognisable style of badging :
