Been following this thread with interest. Question for those logging sightings near Pine Gap here in central Australia - are you cross-referencing dates and times with any public flight tracking data before concluding the craft is anomalous? I ask because I've been doing field recordings out that way a few times over the past few years and the amount of conventional traffic that gets misidentified at night is genuinely surprising.
That said I'm not dismissing what people are reporting. The triangular configuration with silent movement is a pattern that keeps coming up in credible accounts going back decades. What I want to know is whether anyone is capturing audio alongside visual. In my EVP work I've found that audio often picks up things the eyes and cameras miss entirely, and some of the accounts I've read mention a low frequency hum that would absolutely show up on a decent recorder if someone had one running.
Anyone actually doing systematic audio capture during these sightings or is it all visual and video?
