A green laser was shone at a Qantas plane before it landed at Adelaide Airport last night.
The laser was shone at the plane 20 minutes before it was supposed to land and was reported by the pilots.
Although laser light can be blinding this laser did not affect the pilots.
Police say the laser was shone from an area near the Mt Crawford forest.
Police ask if anyone has any knowledge of the incident to please call crime stoppers.
