I seem to recall a 'paper airline' under the name of Southern Airways planning to start up at Bournemouth back in 1990/1/2 i can't remember... They wanted to operate to Brussels, Glasgow, Manchester but nothing ever came of them.
Sounds very similar to EuroDirect's business model when they operated from BOH with J31s in '94/5. Didn't last - (but that may have been because they tried to get too big too quickly and fly ATPs from LGW).
However one problem with the small aircraft business model is there are very few passengers to split the landing/handling fees between. 19 pax in a J31 with the level of fees of Manchester or Amsterdam may also have helped kill EuroDirect.
