Australia: UPDATED - 2008 "cluster attack" caused by boys on bicycles

In an incident in late March 2008, six planes had to alter their flight paths into Sydney’s airport after pilots reported a “coordinated cluster attack” of “up to four” laser beams. This incident has been cited numerous times as perhaps being a dry run or test for some more sinister laser usage.

However, it turns out that this incident was caused by boys on bicycles, apparently acting without pre-planning and not knowing how the lasers would affect pilot vision. During a Feb. 2011 briefing to the SAE G10T laser safety group , FAA flight standards liaison Patrick Hempen said that the truth about Sydney has not caught up with the news stories: “The attacks are usually spontaneous in nature, perpetrated by careless or malicious persons.”

Hempen said that investigation by US and Australian officials revealed that the Sydney "cluster attack" was caused by youths, riding their bicycles on a golf course at night, who stopped and took the occasion to illuminate landing aircraft. He noted that the youths’ local community had a history of acrimony directed at the airport authority due to the construction of a new runway which caused more flights over their residential area.

Hempen also investigated several laser events in the Mideast and found many of the so-called "deliberate attacks" to be similar; they were “events perpetrated by youths, in a party-like atmosphere, without care or knowledge of the havoc that they were causing.”
