The British Airline Pilots Association (Balpa) have called for action to tackle the growing problem of powerful lasers being directed at aircraft.
According to London24.com, Heathrow Airport is a 'hotspot' but Manchester, Glasgow and Liverpool airports are also frequently targeted. More than 1,500 incidents took place last year, compared to just three in 2004.
These incidents involve lasers being shone into the cockpit, often from as far as kilometre away. Typically, this occurs during take-off or landing, and causes a "blinding flash" which can last for minutes.
Pilots warn that the practice is playing "Russian roulette" with the lives of passengers, and are now calling for prison sentences for offenders.
Balpa general secretary Jim McAuslan said: "We want regulations over the sale of high powered lasers strengthened, more prosecutions and action taken through trading standards. Lasers can be bought easily and cheaply. The government should convene a cross-agency summit to discuses how to tackle this problem."
The Guardian reports that there were 153 incidents at Heathrow in 2011. The second most affected airport was Manchester with 148 incidents, Birmingham had 143 and Glasgow 107. Liverpool's John Lennon Airport had 90.
Since 2010, shining a laser or light an aircraft has been a specific criminal offence. A Civil Aviation Association (CAA) spokesman told The Guardian: "We are currently seeing a global surge in incidents of lasers being deliberately shone at aircraft on final approach to airports.
"The aviation industry and the police are doing everything possible to combat the problem and we strongly urge anyone who sees a laser being shone in the night sky near an airport to contact the police immediately."

Pilots call for action over 'laser blinding' at Heathrow
The worst airport in the UK is Aberdeen Airport according to British travellers. The airport, which handles more than three million passengers per year, was given the thumbs down for its facilities including its baggage carousel area, which passengers said is in need of updating.
Luton Airport is in at number 14 and is the least favourite London airport for UK travellers. It's the fifth busiest UK airport and serves as a base for airlines such as easyJet, Monarch and Thomson Airways. One passenger wrote on airline review website Skytrax: "As a frequent flyer all I can say is how embarrassing this airport is as a gateway to our country."
London City Airport is small compared to the capital's four other international airports and is mainly used by business travellers. Passengers said the airport has "expensive parking," although it does offer free WiFi for all. The airport is busiest during the winter months when most airlines fly to top ski destinations.
London Stansted Airport is not the most favoured UK airport by British travellers and was blasted for its "extremely long queues at check-in".

Bristol Airport in North Somerset handles over 5.9 million passengers a year, with Amsterdam, Dublin and Edinburgh the most popular flight routes. It has one of the shortest international airport runways in the country at just 2,011 metres in length, which means large planes are rarely, preventing most long-distance flights.
