Cropdusting - How the lightbar works

We’re in Beautiful New Zealand on aerial topdressing operations.
Hop on board and join us as we go through the procedures used during a sortie.
We’ll take a closer look at the lightbar - a key instrument used on ag ops. It gives pilots the ability to apply fertiliser accurately and evenly across the ground.
10 points to any keen observer who can date this video to the nearest year. There’s a few clues that give it away ;-)
