I was 'hit' in the eye momentarily by one of these from a distance of 150m approx and it caused me to have disturbed vision for a while afterwards. The user was a teenager who had scarpered by the time I'd got to where he had been. To be properly flashed by someone using such a laser whilst in control of a complex piece of machinery in a critical phase of flight is so dangerous as to be almost premeditating murder. It should be considered as a serious crime and not as a prank gone wrong.
