That's why helicopters fly in the dark over Luleå – Luleå

The first squadron of helicopters at Kallax occasionally makes dark flights over Luleå – and even this week. But today, helicopters seemed to fly very low and many readers have heard and wonder why. According to Lasse Jansson, Head of Information Fleet Helicopters, the answer is that you practice visual flight.

– Pilots wear a variety of light-intensifying glasses – Night Vision Goggles, or NVGs – to get a better look at the terrain. They will see where they fly and where they can land, etc.
