LIVERMORE -- A trio of World War II-era warbirds will roar into Livermore Airport for the Collings Foundation's annual Wings of Freedom Tour on Memorial Day weekend.

The planes will be in town Sunday through Tuesday.

A Boeing B-17 Flying Fortress "Nine O Nine"-- one of about 10 in flying condition in the U.S. -- and the one-of-a-kind Consolidated B-24 Liberator "Witchcraft" and a P-51C Fighter "Betty Jane" will land Sunday, allowing attendees to visit, explore and ride the historic planes during the three-day event. Local World War II veterans will also be on hand to discuss their wartime experiences. Visitors may tour the aircraft for a $12 donation for adults and $6 for children under 12. World War II veterans are free. Half-hour flights are available for a tax-deductible donation; flights on the B-17 or B-24 are $450 per person. P-51 flights are $2,200 for a half-hour and $3,200 for a full hour.

Ground tours and displays will be open Sunday from noon to 5 p.m., and Monday and Tuesday from 10 a.m. to 5 p.m. Also, local historic aircraft, military vehicles and memorabilia will be displayed on Monday, Memorial Day. The Swingin' Blue Stars of the USS Hornet will perform songs from the 1940s and '50s in the afternoon.
