A private memorial service will be held Saturday in Las Vegas for Sue Powers, the widow of Francis Gary Powers, the famous Cold War U2 pilot whose plane was shot down on a covert CIA mission over the former Soviet Union in 1960.

At the age of 68, Claudia Sue Edwards Powers died Thursday of respiratory failure in Las Vegas, a week after she began recovering from a coma that she had slipped into on June 5, said her son, Gary Powers Jr. She was 68. "Sue Powers, my mom, was a delightful woman with many friends. She loved life to the fullest. ... She was loved by all who knew her," he said in a telephone interview Tuesday.

Sue was an advocate of preserving Cold War history and had worked as a volunteer at the Atomic Testing Museum on East Flamingo Road "almost right up to her death”, said Troy Wade, who is chairman of the Nevada Test Site Historical Foundation. "I think she was as much of a Cold War warrior as her husband and believed in him and what he did through the events in the Soviet Union until his untimely death in the helicopter crash,” said Wade, a former Energy Department defense chief.

Sue Powers was born Claudia Edwards in Leesburg, Va., on July 23, 1935, and she grew up in Warrenton, Va., and Washington, D.C., where she graduated from Anacostia High School in 1954. After high school, she worked for the Central Intelligence Agency as a psychometrist, testing CIA agents when they returned from abroad to compile reports for doctors who would determine whether the agents were still loyal. Sue met Francis Gary Powers at the CIA in February 1962 after his release from a Soviet prison.

Powers, a CIA pilot for the high-flying U2, was shot down over central Russia by a surface-to-air missile that exploded behind the U2 close enough to disable it. President Eisenhower admitted on May 7, 1960, that Powers had been on a spy mission when he bailed out of his plane at 30,000 feet and he was captured after surviving the parachute jump. The capture turned into an international incident that led to his release on Feb. 10, 1962, in exchange for Soviet KGB spy Rudolph Abel, who had been caught in the United States and convicted of espionage.

While at the CIA, Francis Gary Powers met his future wife. While rounding a corner near their offices, Gary ran into Sue. Coffee was spilled, Gary Powers Jr. said. That led to buying a cup of coffee, which later led to dinner and eventually romance, he said.

Sue left the CIA before their marriage in November 1963. They then moved from the Washington, D.C., area to Sun Valley, Calif., where Francis Gary Powers was a Lockheed test pilot through 1970. He went on to work for a Los Angeles radio station and in 1976 took a job flying a helicopter for KNBC television. He died when his helicopter crashed on Aug. 1, 1977.

After Francis Gary Powers' death, Sue Powers continued to live in the Los Angeles area until 1994 when she moved to Las Vegas. She had established a part-time residence in the early 1980s. The 1994 Northridge earthquake destroyed the family's house in Sherman Oaks and persuaded her to move to Las Vegas permanently, her son said.

Gary Powers Jr., 39, who is founder of the Cold War Museum, a traveling exhibit that pays tribute to his father, said his mother was a supporter of several charitable organizations and organized book fairs with authors to raise money for cancer research. "She loved to read books," he said. She was an honorary chairperson of the Silent Heroes of the Cold War National Memorial Committee.

In an interview two years ago, while helping local Boy Scout leader Steve Ririe's effort to retrieve Cold War artifacts from a plane crash on Mount Charleston, Sue Powers said the experience "brought back a lot of memories with Frank (Gary Powers) and Area 51 because Gary was trained there to fly the U2." She told the Review-Journal, "I had goose bumps here and there”.

A C-54 transport plane crashed on the mountain in 1955 and 14 who were on their way to Area 51 to test the U2 spy plane were killed. A propeller from the C-54 has been restored and is displayed at the Atomic Test Museum with Powers' flight suit and helmet and other memorabilia.

Sue Powers will be buried July 13 in the plot with her husband at Arlington National Cemetery in Virginia. Survivors are Gary Powers Jr. of Fairfax, Va., a daughter, Dee Rogers of Eagan, Minn., and two grandchildren. Instead of flowers, the family requests donations are made in her name to the Cold War Museum.
