Calling all celebrity adventurers!

National Aviation Day is on August 19, so we decided to round up some Hollywood pilots, as well as other stars who have hobbies that get them outdoors and, in some cases, up in the air. From Brangelina's love of flying to Matthew McConaughey's surfing adventures, it's easy to find stars who have taken up some not-so-boring hobbies.

Check out some stars in action below:

    Madonna's a fan of horseback riding ... and has been injured several times after falling from horses.

    John Travolta has had his pilot's license for many years, and owns several aircrafts. However, things haven't always gone smoothly in the air. In 1992, a plane he was flying had an electrical failure and he was forced to make an emergency landing. Yikes!

  • Patrick Dempsey

    He may play a surgeon on "Grey's Anatomy," but in his spare time, Patrick Dempsey likes to hit the road and race. He's competed in several auto races and is the owner of Dempsey Racing and co-owner of the Vision Racing IndyCar Series team.

  • Matthew McConaughey

    Is there anyone cooler than Matthew McConaughey? Yes, and he's called Matthew McConaughy on a surfboard.
