ER-2 tail number 809, is one of two Airborne Science ER-2s used as science platforms by Dryden. The aircraft are platforms for a variety of high-altitude science missions flown over various parts of the world. They are also used for earth science and atmospheric sensor research and development, satellite calibration and data validation. The ER-2s are capable of carrying a maximum payload of 2,600 pounds of experiments in a nose bay, the main equipment bay behind the cockpit, two wing-mounted superpods and small underbody and trailing edges. Most ER-2 missions last about six hours with ranges of about 2,200 nautical miles. The aircraft typically fly at altitudes above 65,000 feet. On November 19, 1998, the ER-2 set a world record for medium weight aircraft reaching an altitude of 68,700 feet. The aircraft is 63 feet long, with a wingspan of 104 feet. The top of the vertical tail is 16 feet above ground when the aircraft is on the bicycle-type landing gear. Cruising speeds are 410 knots, or 467 miles per hour, at altitude. A single General Electric F118 turbofan engine rated at 17,000 pounds thrust powers the ER-2.

James Barrilleaux is the assistant chief pilot for ER-2s in the Flight Crew Branch of NASA's Dryden Flight Research Center, Edwards, California. The ER-2s--civilian variants of the military U-2S reconnaissance aircraft--are part of NASA's Airborne Science program. The ER-2s can carry airborne scientific payloads of up to 2,600 pounds to altitudes of about 70,000 feet to investigate such matters as earth resources, celestial phenomena, atmospheric chemistry and dynamics, and oceanic processes. Barrilleaux has held his current position since February 1998. Barrilleaux joined NASA in 1986 as a U-2/ER-2 pilot with NASA's Airborne Science program at Ames Research Center, Moffett Field, California. He flew both the U-2C (until 1989) and the ER-2 on a wide variety of missions both domestic and international. Barrilleaux flew high-altitude operations over Antarctica in which scientific instruments aboard the ER-2 defined the cause of ozone depletion over the continent, known as the ozone hole. He has also flown the ER-2 over the North Pole. Barrilleaux served for 20 years in the U.S. Air Force before he joined NASA. He completed pilot training at Reese Air Force Base, Lubbock, Texas, in 1966. He flew 120 combat missions as a F-4 fighter pilot over Laos and North Vietnam in 1970 and 1971. He joined the U-2 program in 1974, becoming the commander of an overseas U-2 operation in 1982. In 1983, he became commander of the squadron responsible for training all U-2 pilots and SR-71 crews located at Beale Air Force Base, Marysville, California. He retired from the Air Force as a lieutenant colonel in 1986. On active duty, he flew the U-2, F-4 Phantom, the T-38, T-37, and the T-33. His decorations included two Distinguished Flying Crosses, 12 Air Medals, two Meritorious Service Medals, and other Air Force and South Vietnamese awards. Barrilleaux earned a bachelor of science degree in chemical engineering from Texas A&M University, College Station, in 1964 and a master of science

A National Aeronautics and Space Administration (NASA) Lockheed U-2 aircraft on display at the 1973 Inspection of the Lewis Research Center in Cleveland, Ohio. Lockheed developed the U-2 as a high-altitude reconnaissance aircraft in the early 1950s before satellites were available. The U-2 could cruise over enemy territory at 70,000 feet and remain impervious to ground fire, interceptor aircraft, and even radar. An advanced camera system was designed specifically for the aircraft. The pilot is required to use a pressure suit similar to those worn by astronauts. NASA’s Ames Research Center received two U-2 aircraft in April 1971 to conduct high-altitude research. They were used to study and monitor various Earth resources, celestial bodies, atmospheric chemistry, and oceanic processes. NASA replaced its U-2s with ER-2 aircraft in 1981 and 1989. The ER-2s were designed to carry up to 2600 pounds of scientific equipment. The ER-2 program was transferred to Dryden Flight Research Center in 1997. Since the inaugural flight for this program on August 31, 1971, NASA’s U-2 and ER-2 aircraft have flown more than 4500 data missions and test flights for NASA, other federal agencies, states, universities, and the private sector.

On November 19, 1998, an ER-2 set a world record for medium weight aircraft reaching an altitude of 68,700 feet. The aircraft is 63 feet long, with a wingspan of 104 feet. The top of the vertical tail is 16 feet above ground when the aircraft is on the bicycle-type landing gear. Cruising speeds are 410 knots, or 467 miles per hour, at altitude. A single General Electric F-118 turbofan engine rated at 17,000 pounds thrust powers the ER-2.
