Very aware of the 28 day rule - we currently hold car boot sales on the site hence the car tracks on the google pic. We even have an empty barn on that side which has lots of hangar potential. We're clear of any controlled airspace luckily, there is however a police helicopter base located nearby who frequently pass overhead. I'd assume they'd need notice of any such plans if they were to go ahead, does the CAA require notice of any kind?
