So why don't we use aircraft to transport virtually EVERYTHING? Hey, just airdrop stuff in front of the local Walmart!
Some of the reasons they don't are well stated by other posters; I think that some airdrops would make sense, but can you really, airdrop or land some of the huge, heavy equipment from one place to another safely?
In many cases a truck is the best way to go.
Also, if you watch the show, they are often moving things from one place "up north" to another. They'd need landing strips at everyone of these locations.
ETA: Hey, I like the show too!
