Rossair (PF) Flying school was owned for many years by the legendary Kevin (F@!$ing) M, who sold it, and then it was resold and eventually merged into the Air South organisation. Kevin moved to Emu then ******** and now parts unknown, apparently retired from Aviation.
Recently Air Charter Aust and Rossair merged, having been aquired by a CB based (I think) operator, who also purchased ND helicopters.
