A brilliant blue-white light performs amazing acrobatics for an hour and a half over the city of Brisbane.

Brilliant pulsing blue-white light (like burning magnesium) passed directly over apartment building and began incredible acrobatics across the Brisbane night sky for an hour and a half before heading due west towards the outback. At times the light divided to become two, three or four separate lights of different colours, and at other times it threw off lights like flares. The craft took up space that was normally active with take-offs and landings from Brisbane Airport, however for the duration of the event, no other aircraft were seen. A half hour after the light disappeared over the Great Dividing Range, a fleet of five or six black helicopters came from behind the mountains, and roughly retraced the pathway of the light. Only after the helicopters left did flights from the airport resume. There was absolutely NO media coverage of this event.
Date is approximate.  One of two interesting reports from same source.  We will attempt to contact sources in Brisbane to inquire whether they know anything about it.  PD
