There is an interesting postscript to this story, You will see from the website that Billington is very concerned about "high energy approaches" and features a number of pictures of the aircraft - a German registered Piaggio FW P.149D D-EARY. This was based at Barton and was flown into Ashcroft by the people with who he was having a legal dispute.
Last year - 2017 - the aircraft was sold and is now based over in Yorkshire and is very unlikely to be carrying out "high energy approaches" at Ashcroft ever again.
Even a glance at the website shows someone with a very loud bee in the bonnet..........
The result of the legal action will be interesting to say the least.
