It flies directly into the hurricane, typically penetrating the hurricane's eye several times per mission at altitudes between 500 feet (150 m) and 10,000 feet (3,000 m). If put in the mouth and bitten, the "L-pill"—containing liquid potassium cyanide—would cause death in 10–15 seconds. , Beyond not using American military personnel to fly the U-2, Eisenhower preferred to use non-U.S. citizens. Ground resolution of 9.8 feet (3 m) was required, at a maximum payload weight of 440 pounds (200 kg).  Neither flight proved or disproved the existence of a "missile gap". Size, and thus cost, is kept down by having less endurance than the Global Hawk at around 20 hours, which is still about the same time as a normal RQ-4 sortie even though it is capable of flying for 34 hours. After that, all missions had the U-2 fly outside a buffer zone at least 20 nautical miles (37 km) around China. Soviet radar monitored the U-2 incursion into Soviet airspace in realtime, with radar tracking starting from the time the aircraft crossed into East German airspace. Yefim Gordon, Sergey & Dmitri Komissarov: U.S. Aircraft in the Soviet Union and Russia. The exercise was completed with excellent results, and actual reconnaissance missions began to be scheduled immediately.  Like Eisenhower, Macmillan personally approved the Soviet overflights. In 1977, a U-2R was retrofitted with an upward-looking window so that it could be used for high altitude astronomical observations of the cosmic microwave background (CMB).  In December 1958 Khrushchev boasted that a Soviet missile could deliver a 5-megaton warhead 8,000 miles (13,000 km). That was then discarded in favor of the MiG-25R and reconnaissance satellites. ", "Global Hawk saved, but A-10's chances are dim. Testing in 1964 with the USS Ranger and in 1969 with the USS America proved the concept. Landings are assisted by another pilot at speeds exceeding 120 miles per hour (190 km/h) in a chase car. This is due primarily to its ability to change surveillance objectives on short notice, something that surveillance satellites cannot do. At one time, in an effort to extend the U-2's operating range and to eliminate the need for foreign government approval for U-2 operations from USAF bases in foreign countries, it was suggested that the U-2 be operated from aircraft carriers. When Johnson ordered altimeters calibrated to 80,000 feet (24,400 m) from a company whose instruments only went to 45,000 feet (13,700 m), the CIA set up a cover story involving experimental rocket aircraft. Instead of the typical tricycle landing gear, the U-2 uses a bicycle configuration with a forward set of main wheels located just behind the cockpit, and a rear set of main wheels located behind the engine. Lockheed Corporation originally proposed it in 1953, it was approved in 1954, and its first test flight was in 1955. While not one WC-121N was ever lost on a hurricane hunter mission, by 1969 the Navy was looking at replacing the venerable old bird with a more advanced weather reconnaissance aircraft.

In the wake of the Gary Powers incident, the Taiwanese program of China overflights was redesignated TACKLE, a subset of the new IDEALIST program. Dulles further told Eisenhower, according to presidential aide Andrew Goodpaster, that in any aircraft loss the pilot would almost certainly not survive. To maintain their operational ceiling of 70,000 feet (21,000 m), the early U-2A and U-2C models had to fly very near their never-exceed speed (VNE). However, the Intelligence Systems Panel, a civilian group advising the USAF and CIA on aerial reconnaissance, had recognized by 1954 that the RB-57D would not meet the 70,000 feet (21,300 m) requirement that panel member Allen Donovan of Cornell Aeronautical Laboratory believed was necessary for safety. ", CS1 maint: bot: original URL status unknown (, Shalal-Esa, Andrea. The United States also had to move swiftly to protect its allies: for example after the Soviets announced that Powers was alive, the CIA evacuated the British pilots from Detachment B as Turkey did not know of their presence in the country. , Bissell suggested bringing the British into the program to increase the number of overflights. A skid during flight with no bank was the hint of an imbalance around the longitudinal axis which could be resolved by moving the fuel to the left or right wing tank. Pedlow and Welzenbach 1992, pp. The USAF decided to solicit designs only from smaller aircraft companies that could give the project more attention. The USAF purchased a total of 31 U-2s through the CIA; the transaction's code name, Project DRAGON LADY, was the origin of the aircraft's nickname. The committee was led by Carl F. P. Overhage and was overseen by the Air Force's Gordon P. Saville, and included James Gilbert Baker and Edwin H. Land, who would design the specialized optics in the U-2. Johnson was Lockheed's best aeronautical engineer, responsible for the P-38 and the P-80. The Soviets began tracking the U-2 15 miles outside the border, and over Sverdlovsk, four and a half hours into the flight, one of three SA-2 missiles detonated behind the aircraft at 70,500 feet, near enough to cause it to crash; another hit a Soviet interceptor attempting to reach the American aircraft. Six-thousand-foot (1,800 m) reels of film made from ESTAR Base (PET) were used. It was flown by Major, 56-6693 – wreckage is on display at the Central Armed Forces Museum, Moscow. The company asked Clarence "Kelly" Johnson to come up with such a design.  A secret MI6 bank account paid the RAF pilots, whose cover was employment with the Meteorological Office.  Each modified U-2 also included an additional oxygen cylinder. TR-X could be ready for service in the 2025 timeframe, with a fleet of 25–30 aircraft proposed to replace the nearly 40-aircraft mix of U-2s and RQ-4s. Helicopters are not built to withstand the severe turbulence encountered in hurricane rainbands and eye walls. ", "Scrapping U-2 won't save as much as touted. 181–182, 187–188, 195–197. Despite the loss of designated weather ships, weather observations from ships continue from a fleet of voluntary merchant vessels in routine commercial operation, which have increased in number over the decades.

In May 1957, Eisenhower again authorized overflights over certain important Soviet missile and atomic facilities. He continued to personally authorize each flight, closely examining maps and sometimes making changes to the flight plan. "Eyes in the Sky", Dino Brugioni 2010, Naval Institute Press.  The reconnaissance aircraft was essentially a jet-powered glider. The CIA's Civil Air Transport, aiding the rebels, so badly needed pilots that it borrowed two CIA U-2 pilots despite the high risk to the U-2 program if one were captured. The design was powered by the General Electric J73 engine and took off from a special cart and landed on its belly. Pedlow and Welzenbach 1992, pp. A month before the incident, another U-2 crash landed in rural Thailand. ", Fulfilling CIA officials' fears of a USAF takeover, CIA pilots never again flew over Cuba; SAC retained control over Cuban overflights, which continued until the 1970s under the code name OLYMPIC FIRE. To maintain balance while taxiing and take-off, two auxiliary wheels called "pogos" are attached under the wings. The exercise was critical to continued CIA operation of the U-2, since basing the aircraft in a foreign country was no longer an option. Because the Eisenhower administration could not disclose the source of its intelligence, however, Congressional and public debate over the bomber gap continued. , In late 2014, Lockheed Martin proposed an unmanned U-2 version with greater payload capability, but the concept did not gain traction with the USAF. Typically the term reconnaissance refers to observing weather from the air, as opposed to the ground (for example, ground based weather radar). The program offered high salaries and the USAF promised that pilots could return at the same rank as their peers. Other designs for the 'C' camera were designed but not successful. The sailplane-like wings were so efficient that the aircraft jumped into the air at 70 knots (81 mph; 130 km/h), amazing LeVier who, as he later said, "had no intentions whatsoever of flying". ", "Global Hawk trails U-2 despite retirement plans. , A second flight on 5 July continued searching for Bisons, took photographs of Moscow (the only ones taken by the program), and flew over cloud-covered rocket factories at Kaliningrad and Khimki. , By January 1956, the U-2 had so impressed the USAF that it decided to obtain its own aircraft.
