According to UK CAA statistics, over 1.400 incidents of laser attacks on pilots were reported last year, most of which occurred at Heathrow airport.
In fact, on average four pilots are at risk of being blinded by laser light on approach to British airports every day.
The CAA has warned that if a pilot is blinded or dazzled by a laser light on approach, it could result in a catastrophic incident. According to a regulator, “An aircraft on final approach at 1,000ft has around one minute before it reaches the threshold of the runway and touches down…A pilot dazzled by a laser can be blinded for up to ten seconds followed by over a minute of impaired vision. The risks to passengers and crew are all too obvious.”
