Ok, wenn das JORN an war, hätten die Aussies das Flugzeug sehen können/müssen.
"The JORN radars have an operating range of 1000–3000km, as measured from the radar array. Figure 2 depicts the locations of the three OTHR systems and the JCC, and highlights the coverage of each radar. Of note, the Alice Springs and Longreach radars cover an arc of 90 degrees each, whereas the Laverton OTHR coverage area extends through 180 degrees."
"JORN does not operate on a 24 hour basis except during military contingencies. Defence’s peacetime use of JORN focuses on those objects that the system has been designed to detect, thus ensuring efficient use of resources."
Fragt sich nun halt nur, ob zur gefragten Zeit gerade "Military contingency time" war oder nicht.
