I think the real issue here, is not do we need low flying? (We do)
Or does this lady have the right to live peacefully in the countryside? (She does)
The real issue is how has it got to this stage without a compromise being reached. If the lady in question contacted the MoD and she was told to 'blow it out her ass', and no attempt to explain the need for low-flying or thought of an avoid was made, then quite right her next step would be to take it to the next level.
If however, an avoid was not possible and everything was done to explain to her the operational requirements of the crew, or worse, she did not contact the MoD and then decided to take it to the courts, then I have zero sympathy.
Without knowing the facts of the individual case it would be difficult to come to a conclusion either way.
