I have spoken to Lindsay personally about this and he is perfectly happy to pay for the cost of manning the tower if that is what is required te ensure an acceptable level of safety.
The cost is not in the millions of dollars. When Qantas or the military do training at Avalon the cost of manning the tower is about $380 per hour.
Airservices even man the tower when the Formula ! cars are airfreighted in.
And if the CASA safety study for Avalon is flawed why don't you do something constructive to get it corrected - or won't they take any notice of someone who isn't even game to put a name to the objection!
