I hope this sheds some light. Navair were taken over by CAS in about mid 2003 and operated out of the old Navair hangar which CAS rented off FY as he held the lease from BAL (and still does i believe). In about 2004 they were sold and began operating as SFTC and until very recently had been operating from the same hangar until they went into administration and are now operating out of remote nsw.
As for FY, not sure what he is up to, though I know he ridded himself of a few of the old warriors and archers a short time after he sold navair.
