Presumably the Government keep a close eye on these things and are not wanting negative press aimed at sites that companies could close at the drop of a hat. It won't reflect well if Hitachi gets negative press and just decides to close the doors, leaving Brits out of work. Let's face it, their UK product has been terrible and they currently have their fleet of 800-802's visiting Eastleigh to be glued back together - this in itself should be in the media! Can you imagine the frenzy if Boeing or Airbus suddenly started to send entire fleets of aircraft for work to fix cracks?
