When i first read this thread i thought it was a wind-up...
How can the authorities possibly find it safe for a bloke to buzz around the skies without being able to hear?? I dont want to even start listing the extensive hazards he presents to himself, and more importantly the greater flying community. It is stated that he plans his flights meticulously to ensure all is pre arranged with airservices and so on, but how often in our own experiences has a flight gone exactly to plan?
Seriously how devoid of logic is it to celebrate the dangers this guy is creating? How he is licensed to operate by himself is simply beyond me. Im all for him getting up there and enjoying his flying experiences but as esreverlluf said, get a hearing offsider and stop creating hazards.
