Helicopters are life saving aircraft and the crews are highly skilled in their operation.
Anytime they operate they attract the public who are keen to photograph or see them in action.
All helicopters cause a large amount of down draft and this can blow people over or blow debris about.
The rotor blades , along with the tail rotor are to be totally avoided.
As we found on Saturday sometimes the public tried to get a little too close and one person was a little rude to an officer who was just trying to prevent an accident.
Please help us to keep you safe , keep your distance.
