Oregon Christmas Tree Harvest With Helicopter. Amazing Pilot!

Some blueberry farms and vineyards here in Oregon use large fans to mix the higher/warmer layers of air with cooler/lower layers, or “drain” cold air away (by blowing it straight up, it apparently doesn’t come back down). This keeps cold air from pooling in certain areas, which is what is needed to cause frost damage. Here are some large mixers, which might be mistaken for small windmills. These are powered by propane (I think), which is what the tanks nearby hold. The heat produced is a bonus, even a degree can make all the difference: [link] So while helicopters used to shake water off of crops can sound crazy, it’s literally a big mobile fan you can call in when needed to save your established perennial crop from much more expensive problems (like a disease epidemic, which now requires bacteria codes/fungicides instead of just burning some fuel. Which can make sense. We also use helicopters to harvest Christmas trees. It’s too damn wet in the fall/winter to run most wheeled equipment up and down those horrible on red clay hills, which often have artesian springs temporarily form, resulting in clay mud that can grab and hold all land vehicles.
