The RAAus had two of their own in house investigators on site by the afternoon the following day. They are investigating with local police.
Power lines don't seem to be a factor. If it was a weather factor that caused both aircraft to break up in flight then it was a huge one. I doubt if this was the case. The Drifter was a two seater and the Thruster was either a 83,84 or 85 single seat model (very good chance i built it). They are all pretty much the same now as all have been upgraded engine and airframe wise. have never known either type to completely detach a wing before or seen such complete destruction on a Thruster. My personal view is mid air a tangle and a long fall almost vertical. But lets see what the coroner says.
