Wiltshire Police are warning of the dangers of shining laser pens at flying aircraft.
The latest incident involving a laser pen occurred at approximately 9.24pm on Sunday in Calne.
The pilot of an Airbus 321 - descending into Bristol airport - reported upon landing that a green laser pen had been shone into the cockpit of the aircraft. It is believed that the laser pen was being used by someone in the Calne area.
A spokesman for Wiltshire Police said: "Shining any form of powerful light in the direction of a flying aircraft is foolish at best and fatal at worst.
"Fortunately, on this occasion, the pilot was still able to land the plane safely at Bristol airport but it could have been a very different story."
Anyone with information is asked to contact Wiltshire Police on 101 or Crimestoppers on 0800 555 111 where information can be left anonymously.
