  Plenary Session:

Keynote Speaker (Invited): Congressman David L. Hobson (R-Ohio, 7th District)
Rep. Hobson is chairman of the Energy and Water Development Appropriations Subcommittee and is a senior member of the Defense and VA-HUD Appropriations Subcommittees. Rep. Hobson also serves as Assistant Majority Whip.

Land Navigation—Where Is It Going?
The future of land navigation is at a crossroads. GPS and its augmentations may provide inexpensive and reliable radionavigation for land based users, but is it enough, or is it the right direction? You will hear from industry leaders in farming, highway transportation, mapping, and other areas about where they think the direction of navigation should be headed.

Dayton Attractions

Dayton, Ohio - Something for Everyone
Best known as the birthplace of aviation—where Orville and Wilber Wright dreamed up their flights of fancy—Dayton is home not only to aviation marvels, but to a myriad of exciting attractions, including world-class museums, outstanding art and cultural offerings, sport and recreational activities, shopping, and fine dining. Dayton has something for everyone.

Dayton Aviation Trail
Aviation aficionados flock to the Dayton/Miami Valley area. With more than 50 sites crucial to the history of aviation, the region boasts plenty of artifacts and exhibits to keep your head in the clouds. Take the self-guided Dayton Aviation Trail driving tour to orient you to the area’s aviation landmarks. For information, visit the Aviation Trail building at the Wright Dunbar Plaza near the Wright Cycle Shop.

U.S. Air Force Museum

Wright B Flyer—Dayton-Wright Brothers Airport
The Wright B Flyer was built by a group of aviation experts who, in 1973, took on the challenge of building a flyable look-alike. The Wright–B Flyer look-alike is housed in a replica of the Wright Brothers’ Huffman Prairie hanger. For a fee, you can travel back in time to experience early flight.

United States Air Force Museum
Dayton is also home to the world’s largest and oldest military aviation museum. The U.S. Air Force Museum boasts 10 acres of exhibits, including a hanger highlighting Cold War-era memorabilia. More than 300 aircraft and missiles and thousands of artifacts are on display. Don’t miss the Air Force One collection, the Apollo 15 space capsule, and, of course, Wright Brothers memorabilia. You can also experience the thrill of flight at the on-site IMAX theatre.

National Aviation Hall of Fame
It seems only fitting that the birthplace of aviation would include a National Aviation Hall of Fame to honor the men and women who have contributed so much to flight. The National Aviation Hall of Fame is adjacent to the U.S. Air Force Museum and offers interactive educational exhibits emphasizing the scientific and historical contributions of air and space pioneers. Since 1962, the Hall of Fame has honored 178 men and women in all aspects of aviation.

The Citizen’s Motorcar Company: America’s Packard Museum
For those who prefer their transportation on the ground, the American Packard Museum, located in the original 1917 Packard Dealership, displays an array of automobiles and artifacts from the Packard Motorcar Company. This museum was named one of the 10 best in the United States by Car Collector Magazine.

The Citizen’s Motorcar Company: America’s Packard Museum
For those who prefer their transportation on the ground, the American Packard Museum, located in the original 1917 Packard Dealership, displays an array of automobiles and artifacts from the Packard Motorcar Company. This museum was named one of the 10 best in the United States by Car Collector Magazine.

Art and Culture
Dayton’s beautiful new $130 million Benjamin and Marian Schuster performing Arts Center offers performances by the Dayton Opera, the Dayton Philharmonic Orchestra, and the Dayton Contemporary Dance Company. Theatre goers will enjoy hit Broadway performances in the 2,300 seat Mead Theater.

Of course the Dayton Art Institute is home to many world-class collections and thought provoking exhibits. The Renaissance inspired Italian villa, listed on the National Register of Historic places, showcases permanent and special collections of art ranging from Chinese artifacts to works by American artist Andy Warhol. Highlights include such paintings as Claude Monet’s “Waterlilies” and Georges Rouault’s “Madonna of the Fields.”

Government Reservations. A limited number of government rates are available. The U.S. government rate will be honored only for those persons traveling with U.S. government travel orders and paying for the room with a U.S. government-issued credit card. Failure to provide these validations at check-in will result in your reservation being honored at the group rate. If you do not meet these criteria, please do not reserve a government-rate room, as this will deny qualifying individuals from obtaining a room. Government contractors and/or retired or non-active military personnel do not qualify for government rate rooms.

Attention International Participants

We recommend that you apply for your visa at least two months in advance due to security related policies that have greatly increased the processing time for visa applications.

U.S. consular officers now interview most applicants as part of the application process. This can add additional time and delays. Currently there is a mandatory security check period of 30 days for people whose passports are issued from several countries, including China, North Korea, and most middle-eastern countries. Furthermore, the U.S. State Department requires citizens of many countries to obtain visas to attend any scientific program.

After October 1, 2003, citizens from visa waiver program (VWP) countries also will be required to obtain a visa if they do not have a machine-readable passport. You are urged to contact the nearest U.S. embassy, or consulate, to find out if your government has been granted a one-year delay of this rule or if you will need to obtain a new passport prior to traveling.
