Laser pen menace

How dangerous are lasers to planes? - BBC News

Laser pens are not illegal in the UK and are widely available online,
costing anything from £20 to £500. Those sold in the UK are usually
classified in accordance with the current safety standards.

However, stronger lasers can be imported via the internet. One South
Korean-based website offers to ship the "world's most powerful handheld
laser" to the UK, starting from $199 (£137).

According to David aylor, of National Police Air Service (NPAS), it is "extremely easy" to
pick up lasers on the internet that are about 5,000 times more powerful
than the strength of a typical classroom pointer.
