.

Special thanks to the Aerospace Engineering Department at the University of Maryland for making

this event possible.

Visitor's parking uses digital pay stations, for more information on their use go to: https://www.transportation.umd.edu/paystation.html It is complicated enough that there is actually a video online there to explain how to use them! And you can use your phone or there is a mobile app (if you don't want to use cash or a credit card)!

College Park Aviation Museum 1985 Corporal Frank Scott Drive College Park, MD 20740

Mission Statement The College Park Aviation Museum is dedicated to preserving and promoting aviation innovations at College Park Airport and in Prince George's County while fostering research, inventiveness, and lifelong curiosity about the history and science of flight.

Historic Venue The museum is a 27,000-square-foot, state-of-the-art facility located on the grounds of the world's oldest continuously operating airport in College Park, Maryland. The airport was founded in 1909 when Wilbur Wright came here to give flight instruction to the first military aviators.

Exhibits Visitors to the museum step into an open 1 1/2 story exhibit space, which highlights the display of unique aircraft and artifacts and tells the story of the airport's many firsts in flight to today. The museum gallery contains historic and reproduction aircraft associated with the history of the airfield, as well as hands-on activities and interpretive areas for children of all ages. Changing exhibits and new programs every month keep visitors coming back for more.

Directions to College Park Aviation Museum Turn onto Campus Drive at traffic light at the north entrance of the University of Maryland. Proceed through 4 traffic lights. The next traffic light is Corporal Frank Scott Drive, turn left. Continue to entrance of the airport parking lot. Turn right onto service road and proceed to museum parking lot.
