Talking yesterday to a witness who didn't see the actual impact but the immediate aftermath - the Pawnee was observed flying another circuit, landed on 06 and then taxied to the far end (i.e. where it is in the photos).
Allegedly the Pawnee pilot asked the first responders "where's the Cessna?" in reference to the aircraft that allegedly taxied across 06/24 causing him to initiate his go-around. A good question - what DID happen to the recalcitrant Cessna?
Thanks for posting the photos/diagrams, helispotter. I don't think your final diagram is quite right - note how the wreckage trail of VH-EDJ parallels 11/29. I'm sure when we eventually see the ATSB report, all will be revealed.
A terrible business.
