[Q]: Question: In what year was CIA pilot Francis Gary Powers born? Passage:Strategic Air Command was formed by the United States Air Force after World War II to provide an active defense against any surprise attack by the Soviet Union. Though it had been an ally against Germany and Japan during World War II, by 1948 the Soviet Union showed a propensity to instigate problems with Britain, France and the United States. In August 1949, the Soviet Union detonated its first nuclear weapon and by the early 1950s had detonated a hydrogen bomb. The war of words between the two superpowers escalated during 1950s and 1960s into a nuclear arms race. By 1970 the United States was using a "Triad Defense System" composed of nuclear submarines armed with nuclear missiles, land based intercontinental ballistic missiles with nuclear warheads and bombers capable of delivering hydrogen bombs on enemy targets. The Boeing B-52 Stratofortress bomber had been designed in the early 1950s by Boeing Aircraft Company to give the United States Air Force the capability of delivering nuclear weapons far inside the territory of Soviet Russia. The planes were to fly at high altitude with enough fuel to hit their target. In May 1960, the Soviet Union made known its capability to shoot such high altitude planes out of the sky by using a surface to air missile to strike CIA pilot Francis Gary Powers' U-2 spy plane over Russian territory. From that point on, the high-altitude B-52 had to be modified to conduct missions at low level, something it was not intended to be.

[Q]: Question: Which of the two festivals where McCartney was scheduled to headline has existed longer? Passage:On 15 February 2016, McCartney announced two initial festival dates in Europe for the upcoming summer. These two headlining performances at Pinkpop Festival in Landgraaf, Netherlands and Rock Werchter in Werchter, Belgium were revealed before the initial revelation of the "One on One" tour. These tours would feature mostly similar elements of the "One on One" performances yet with a condensed set list to allot for festival curfew limits and less stage elements given restrictions. In the wake of the passing of notable Beatles and McCartney producer George Martin, McCartney announced the initial "One on One" dates for North America and Europe. In North America, McCartney's visit to Fresno, California would mark his first performance in the city, and his performances in North Little Rock and Sioux Falls would be his first performances in the states of Arkansas and South Dakota respectively. Elsewhere in North America, McCartney would perform in Portland after an eleven-year absence following his 2005 'US' tour. The two shows in Vancouver would follow his previous performance in the city at the BC Place stadium in 2012, yet this tour would feature two shows in the neighboring Rogers Arena after the pyrotechnics during his concert at BC Place accidentally damaged the stadium's new roof. McCartney's Seattle show would mark his shortest absence from any North American city on the tour announced currently, as he performed at the city's Safeco Field during the inaugural year of the 'Out There' tour. McCartney announced a performance on 16 March in Minneapolis at the Target Center. This show would take place on 4 May 2016, less than two years after McCartney's last performance in the city at the adjacent baseball stadium sharing a corporate sponsor with the arena, Target Field. Due to high demand of tickets a second show in Minneapolis was announced the next day and would take place on 5 May.
