Here is some of the latest "gossip" from Parafield.
The mid-air incident may (or may not) have happened before (or after) the TWR opened, and there were more (or possibly less) than the maximum permitted (of 5) aircraft operating in the circuit.
What I have seen with my own eyes, is a Tobago parked in the far NE corner of their hangar with a green tarp covering the fin and rudder. This suggests the rudder has been clipped by a wing, a wheel or a prop.
Callsign might have been VH-YTG.

The media have a sniff of it and have been ringing around the flight schools asking questions but not getting too much cooperation
AFAIK.
