USS HORNET MUSEUM Come aboard this World War II aircraft carrier that has been converted into a floating museum. The Hornet, launched in 1943, is 899 feet long and 27 stories high. During World War II she was never hit by an enemy strike or plane and holds the Navy record for number of enemy planes shot down in a week. In 1969 the Hornet recovered the Apollo 11 space capsule containing the first men to walk on the moon, and later recovered Apollo 12. In 1991 the Hornet was designated a National Historic Landmark and is now docked at the same pier she sailed from in 1944. Today, visitors can tour the massive ship, view World War II-era warplanes and experience a simulated aircraft launch from the carrier's deck. Exhibits are being added on an ongoing basis. Allow two to three hours for a visit. Wear comfortable shoes and be prepared to climb steep stairs or ladders. Dress in layers as the ship can be cold. Arrive no later than 2 p.m. to sign up for the engine room and other docent-led tours. Children under age 12 are not allowed in the Engine Room or the Combat Information Center.
$6-$14; free children age 4 and under with a paying adult. Daily, 10 a.m.-4 p.m. Pier 3 (enter on Atlantic Avenue), Alameda Point, Alameda. (510) 521-8448, www.uss-hornet.org.<
