Bruce Johnstone...
I stand to be corrected here...Ex MD of Rossair, founder of Solenta, now founder of Qwila. That's the link and the fact that some Rossair people went to Qwila.... but reality is that Rossair people went to Exec Turbine, Solenta and Qwila so there are linkages everywhere if that's what you are looking for. Personally, I wouldnt look for anything sinister here... lots of good Rossair people and happily they have been snapped up.
As for B Johnstone -
My two cents once again!
