College Park Airport
You won't be seeing any A-380s touching down at College Park Airport. The runway is only 2,600 feet long (jetliners need about 8,000 feet). We bet Wilbur Wright had no idea what the future of aviation would look like when he first brought military pilots here to train a century ago. Today, you can take the half-hour Metro ride from downtown Washington, D.C., to visit the on-site aviation museum. Temporary exhibitions are put on in conjunction with the Smithsonian, and there are classic aircraft on display, including a 1910 Wright Model B reproduction and the biplane-like Berliner Helicopter No. 5, which made its first controlled flight from here in 1924.
Price: Museum entrance $4 per person.
