A trio of World War II-era warbirds roared into Livermore Airport for the Collings Foundation's annual Wings of Freedom Tour on Memorial Day weekend. The planes, 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" landed on Sunday and stayed through Tuesday.

Local World War II veterans were on hand to discuss their wartime experiences. And visitors, who paid the requested donation, got to tour the aircraft. And flights on the antique aircraft were also available.

There were also ground tours and displays of local historic aircraft, military vehicles and memorabilia displayed there on Memorial Day. And the Swingin' Blue Stars performed songs from the 1940s and '50s in the afternoon.
