2 Best Sights in San Diego, California

By day, the streamlined edifice looks like any other structure in the park; at night, outlined in blue neon, the round building appears—appropriately enough—to be a landed UFO. Every available inch of space in the rotunda is filled with exhibits about aviation and aerospace pioneers, including examples of enemy planes from the World Wars. In all, there are more than 60 full-size aircraft on the floor and hanging from the rafters. In addition to exhibits from the dawn of flight to the jet age, the museum displays a growing number of space-age exhibits, including the actual Apollo 9 command module. To test your own skills, you can ride in a two-seat Max Flight simulator or try out the Talon Racing simulator. Movies in the 3D/4D theater are included with admission.

Interactive exhibits here are artfully educational and for all ages: older kids can get hands-on with inventive projects in Studio X, while the five-and-under set can be easily entertained with interactive play stations like the Ball Wall and Fire Truck in the center's Kid City. The IMAX Dome Theater, which screens exhilarating nature and science films, was the world's first, as was the Fleet's "NanoSeam" (seamless) dome ceiling that doubles as a planetarium.
