Stop slagging the Pawnee driver and gliding ops, please.
There is intense speculation about what has happened WRT to who was doing what at which RWY etc.
Please let the experts on the ground do their work, and please allow accurate and primary source facts emerge (from CCTV, from eyewitnesses, first responders etc.).
There are posters on this discussion who know the people involved, and operate out of YCAB, listen to what they might be saying.
Of course the trolls and imbeciles will now come out and slag the ATSB, the police, first responders, YCAB, Pawnee drivers, gliders, Jabiru pilots, CASA, Airservices, the illuminati, chemtrails...
