Would transmitting on a radio have prevented this accident?
Most of the places I operate in are saturated with absolute rubbish on the radio. Makes things worse, made up radio calls, 7 hour long readbacks.
Anytime I operate into an aerodrome where gliders operate I expect the worst, cos you're gunna get it. I've never met a glider pilot yet that knows what a radio is for other than to guide the tug pilot when they're starting a tow.
