Unserviceable or Unairworthy
The Airframes are neither but they have suffered BOREDOM trauma and will now need counselling/cascading sessions, and go on to the couch to be told they are still loved and its not their fault.
They will then be given a walk around the peri track to get them accustomed to daylight and a nice wash and polish.
After a short 'holiday' at Membury they will be as good as new even if the organisation they belong to is a pile of C...p,and dis-organised by Twatter Control.
