I am sorry but this has to be a wind-up. Don't come running to blame someone else because you were stupid enough to pay that sort of money upfront to a flying school of all places!!
If you had bothered to do any research you could have easily found out that the Cabair Group was in serious trouble. NEVER NEVER pay a large upfront sum to ANY flying school unless you do so on a credit card which will offer you protection against bankruptcy of a service provider. To then put in another lump sum to try and keep Cabair going is just totally bizarre. You can blame anyone you like, the fact of the matter is though that plenty of people were capable of doing their research and as a result didn't go to Cabair.
