Military aircraft, cargo jets and commercial airliners are among the dozens of planes you can climb aboard this weekend at Ted Stevens Anchorage International Airport -- and it won't cost you a thing.

The Great Alaska Aviation Gathering is once again taking place this weekend at the airport's FedEx hangar.

Alaska is considered the nation's "flyingest" state, home to more pilots and aircraft per capita than anywhere in the world.

The Gathering draws an estimated 25,000 people, who get the chance to understand the aviation industry's impact on the state -- as well as its always-changing flight conditions.

"Learning a lot about it this weekend, it's very adventurous," said Robert Wellborn, a visitor from Dallas. "With the winds, the weather, you never know what you're going to get here."

The Gathering takes place from 9 a.m. to 5 p.m. Saturday, and from 10 a.m. to 5 p.m. Sunday. Admission and parking are free.
