Aerial Topdressing Planes at work, Taumarunui, 4/9/2017 HD

Over four days at the start of September 2017, some paddocks in a farm near my home were the target zone for aerial topdressing, mostly by one aircraft, although on the final day a second plane joined in the effort around midday. I lost count at how many runs they made, but would roughly estimate between 150 and 200, largely with the same approximate drop zone. Mostly filmed from home, with a short stint closer to the action. They had a fast turnaround, taking only about 4 minutes to take off, fly to drop zone (3km from airport), discharge load, fly back to airport, land, reload and take off again. So when both aircraft were in use they were loading about every two minutes.
