A matter of time.
l remember passing Manchester heading north in `93 on " guy fawkes " night and having a problem with lasers criss-crossing the sky ( l mean strong enough to light clouds which was the intention plainly). l made a report to atc from above 14,000ft, asking that the police investigate. My co-pilot, who was medicaly trained, kept his/her head down `till it stopped.
Our very own lawyer has got this right, bang `em up if caught "playing" with aircraft.
