I have also heard these rumours, although they have not come from my usual "relible" source.. ... if my source doesn't know then dont pin ya hopes up.
As far as I am aware 4 different companys wanted the Ground school, although it would involve taking on a Very "hefty" loan that sft took out to build it.. so however has bought it will have only bought just the ground school... no one is stupid enough to take on the flying school too, i have seen the loan involved on that one and its not pretty!!!! I also have a fair idea of who it might be.. although I cannot tell.
and..... yes Bournemouth needs another school on the ground, deffinatly!!. someone was going to build one anyway as there was a slot on the field, but now it may be taken...... I can only hope!
