I feel bad for guy who tweeted as someone from East Texas. Main reasons I want to go into hunting is to the keep wild boar population in check, or at least slow their growth.
The sharpest shooters can get a few as they scatter, they are damn smart and very capable.
Plus there are far easier solutions. Poisoned corn does about the same thing as mines, but with less risk (assuming you put up signs) and cost. Both are probably still bad ideas, though, because of the effect on other wildlife.
I don't like poisoned bait for broadly similar reasons; I'd like more targeted slaughter. It's not easy to get a big gang that close together.
Unless you can guarantee you'll kill all the hogs that scatter due to the helicopter--not just the ones you see!--then it's likely counterproductive.
