I don't think it has anything to do with the Phenom accident.
The microlight school, Clearprop, has been bought (the Redlands operation too) by someone who has seen fit to close down the Blackbushe 'branch' no doubt leaving several disgruntled students. Someone on Facebook (don't subscribe so I know nothing about it nor do I want to) has added 2 + 2 and made an incorrect assumption.
I've been trying to ascertain who it is that's bought the school without success; the website is still running and still advertising instruction at Blackbushe.
Going by what's happened to other airfields, my guess is that Redlands arfield has been bought by a property developer.(but I hope not)
No doubt this will now appear on this Facebook thing as 'fact'.
