Port Strobe:
Can I ask what exactly Mr & Mrs Public are doing out wandering aimlessly around the apron in the first place?
Perhaps enjoying being part of the activities at one of those many airstrips such as Popham, or the PFA Rally (Kemble), or any of the other GA airfields or strips where there is no such thing as "the apron" ......
I don't think anybody in the thread has mentioned considering your pax eardrums .... by moving or covering the headset mike before yelling 'Clear' anything!
