Bit of a difference between what happened at Boscombe Down and what might come to pass at Wattisham.
Airwork were in default from day 1 at Boscombe Down due to insufficient atcos, never mind any validated staff. An Airwork chief banana, RAF-retired, called in some RAF help and the MOD wanted the civvies out; which happened in due course.
SERCO have held the Wattisham ATC contract, compared to Airwork at Boscombe, for longer. A lot longer.
