Nice video. Crop dusting has sure changed over the years with better aircraft & electronics.
My goal as a kid was to be a crop duster. Being raised on a farm I always loved watching them fly.
When I was 16 I got a job as a loader boy at a crop dusting outfit. We'd start at the crack of dawn, work a few intense hours, & take the mid-day off. We'd repeat the process in the late afternoon. We didn't fly much during the day due to high temperatures. Our airport was 4,700 in elevation & those AgWagons didn't have the power to haul much load.
During the mid-day break I'd take flying lessons from one of the duster pilots who had his CFI. The lessons were kind of hit & miss but I did manage to get my PPL right after my 17th birthday.
After loading, cleaning, & taking care of the airplanes & chemicals I learned that crop dusting wasn't going to be my future.
I still enjoy watching them fly though.
