It’s easier to see from the air. The advantage of a helicopter (as opposed to an airplane) is that is possible to fly slow or even stay still in the air. Helicopters are therefore an ideal way to inspect various locations.
HeliAir has quite a bit of experience with inspection flights. We can even mount our stabilized High Definition camera system for recordings of high quality or heat-sensitive imaging, often used to check energy loss and electricity lines, as well as gas detection cameras for pipeline inspection.
