The degree of secrecy is quite worrying. Sadly, the families of the deceased have to suffer even more with the Circus that Oz Army Air Corps is presenting.
TopOwl is an interesting question. What most TopOwl pilots say, is that it is an incredible safety/SA enhancer. They are able to see through the visor to determine colour, they do not have to tilt their heads upwards to view other info on the cockpit display, a very big improvement on NVG HUD. All of the most critical information is in their field of view no matter where they look. If the NVG tubes fail, or vis reduces, they have a fantastic display for Instrument recovery initiation.
