Juneau, the state capital, is not excessible by road. Airplane and boat are the only way to reach that city. If you have ever been to Alaska, you would see that there are a lot of small airplanes. In fact, there is a row of houses which back onto the railway in Anchorage that has a runway along the back, and every house has an airplane. I saw this in May when my wife and I were there.
Unfortunately, there is no breaking story here. It is a necessary form of transportation in Alaska.
