You can land a helicopter in your garden as much as you like, the 14 and 28 day rule applies only to land not within the house curtillage...
Dont you think that is crazy and unfair? Surely in a fair society this should not be allowed? I am not saying ban all helicopters, I am saying dont allow people to do things like this which could be hell for innocent neighbours. Helicopters should only fly from designated airfields, what is so wrong with that? They can be very noisy and some thought needs to be given to that when making laws.
When they make a quiet helicopter then you can allow them to do what they like......
