Saw a statistic somewhere saying the career cropduster will crash 7 times in his life. As a CAP search and rescue pilot and ground team leader, we went after many a crop duster who "bounced" his plane on his runs.
Related -- an old crop duster told of one spot in one field near a grove that a buck deer was protecting. Every pass he made near that section, the buck would try to spear him, easily clearing the corn the duster was flying over at tassel height (about 9' -- or nearly 3 meters). He was worried the buck would actually hook his main gear.
When they come to power lines they make a decision, over or under. Some prefer under, because they can cut out the peripheral runs. Others always go over, afraid they'll eventually either tear off their rudder or lose their mains.
I *love* watching them.
At the airport, watching them come in at the end of the day, they are absolutely bushed. They go through a little of what an aerobatic performer goes through -- except for 15 or more hours a day. They spray while there is light to spray. Wreaks hell on their body, physically.
Fascinating breed of men and women.
The technology is amazing! Our search and rescue planes have high-tech cameras that can identify aircraft aluminum and aircraft paint as you fly a search route. Select what you're looking for, the computer will alert you if you fly over it (hey... marijuana growers.. we can even tell what type of marijuana you have in your grove, case you wondered how so many friends get busted). Well, some of these ag planes have high tech cameras that automatically adjust the spray for those areas that have insect damages and those that don't. The profit margins can be tweaked a bit by judicious spraying, rather than a blanket of the same dose over everything in the field.
Times have changed!
