We hear a great deal about how dangerous hand held laser lights are for pilots flying aircraft, and how they can temporarily dazzle air crew. Fine, but we are talking about 1 person with a relatively small, single beam unit. If that can cause a serious risk, why isn't there any risk when a laser light show of
this magnitude is conducted in the city centre? (Brisbane Festival next September.) This is a serious question, and I'ld be interested in knowing why there is no danger under these circumstances.
