As bigger and better high rise buildings went up in Shenzhen, China, a fashion came of having large randomly pointing laser beams mounted on the roofs. At night they would be spearing through the air on returning to the heliport. Not too much of a problem. Seeing one of them coming towards you closing your eyes or turning your face away was sufficient. Then some burke disconnected their automatic one and decided to use it manually and guess what was the most attractive target.
We knew something was wrong when the beam, instead of sweeping past, stopped and hovered around the aircraft's position. He wasn't a very good short so the beam wasn't hitting the cockpit but was very close, stopping above, below and either side. Getting fed up with this I switched off the anti-coll, position and cabin lights, broke hard to starboard and dived off 500ft. The passenger didn't even wake up.
I put in the complaint telling them which building it was but it went on, and so did we, lightless, for another couple of days before we were told the police had sorted it.
