A red-winged blackbird perches on a fire hydrant at NASA's Kennedy Space Center in Florida. The center shares a border with the Merritt Island National Wildlife Refuge. More than 330 native and migratory bird species, 25 mammals, 117 fishes and 65 amphibians and reptiles call Kennedy and the wildlife refuge home.

Robert Cubbison examines a model of the Lockheed YF-12 Blackbird in the test section of the 10- by 10-Foot Supersonic Wind Tunnel at the National Aeronautics and Space Administration (NASA) Lewis Research Center. The YF-12 was an experimental fighter version of Lockheed’s A-12 reconnaissance aircraft which had been developed into the renowned SR-71 Blackbird. NASA possessed two YF-12s at its Dryden Flight Research Center which could be used by researchers at all the NASA centers. During its nine-year life, the Dryden’s YF-12 research program logged 297 flights with approximately 450 flight hours. Lewis researchers were studying the YF-12’s inlet airflow in the 10- by 10-foot wind tunnel in late 1977. The advanced supersonic cruise aircraft of the time used mixed-compression inlets. These types of inlets were prone to flameout during atmospheric disturbances. Researchers at Lewis and Dryden developed a program to study these flameouts by artificially introducing flow disturbances. Testing at Dryden with a specially-equipped YF-12 aircraft yielded limited results. Lewis’ tests in the 10- by 10 were unsuccessful at inducing upstream disturbances. The researchers used two methods—a falling plate and a servo-driven wing.

KENNEDY SPACE CENTER, FLA. - An adult male red-winged blackbird perches on a shrub in a marsh on the Merritt Island National Wildlife Refuge. Males have glossy black feathers except on the epaulets of their wings, where they are scarlet bordered with buff or yellow. The birds do not attain full adult plumage until their third year. The refuge was established in 1963 on Kennedy Space Center land and water not used by NASA for the space program. The marshes and open water of the refuge provide wintering grounds for 23 species of migratory waterfowl, as well as a year-round home for great blue herons, wood storks, cormorants, brown pelicans and other species of marsh and shore birds.

STS-83 Mission Commander James D. Halsell, Jr., gives a thumbs-up after he is assisted into his launch/entry suit in the Operations and Checkout (O&C) Building. Halsell is on his third space flight, having served as pilot of both STS-74 and STS-65. He is a lieutenant colonel in the Air Force and a former SR-71 Blackbird test pilot and holds master's degrees in management and space operations. Halsell will have responsibility for the success of the mission and will operate and maintain Columbia during the Red, or second shift. He will also assist with a materials science experiment and a protein crystal growth payload during the 16-day mission. Halsell and six fellow crew members will shortly depart the O&C and head for Launch Pad 39A, where the Space Shuttle Columbia will lift off during a launch window that opens at 2:00 p.m. EST, April 4

Dryden Flight Research Center's SR-71B Blackbird aircraft, NASA tail number 831, is destined for the Kalamazoo Air Zoo museum in Kalamazoo, Mich., and the F-18 High Angle-of-Attack Research Vehicle (HARV) aircraft, NASA tail number 840, is going to the Virginia Air and Space Center in Hampton, Va. NASA's SR-71B was one of only two SR-71 trainer aircraft built, and served NASA in that role, as well as for some high-speed research, from 1991 to 1999. The F-18 HARV provided some of the most comprehensive data on the high-angle-of-attack flight regime, flying at angles of up to 70 degrees from the horizontal. The HARV flew 385 research flights at Dryden from 1987 through 1996.

STS-94 Mission Commander James D. Halsell, Jr., prepares to enter the Space Shuttle Columbia at Launch Pad 39A in preparation for launch. Halsell is on his fourth space flight, having served as commander of STS-83 and pilot of both STS-74 and STS-65. He is a lieutenant colonel in the Air Force and a former SR-71 Blackbird test pilot and holds master’s degrees in management and space operations. Halsell will have responsibility for the success of the mission and will operate and maintain Columbia during the Red, or second shift. He will also assist with a materials science experiment and a protein crystal growth payload during the 16-day mission. Halsell and six fellow crew members will lift off during a launch window that opens at 1:50 p.m. EDT, July 1. The launch window will open 47 minutes early to improve the opportunity to lift off before Florida summer rain showers reach the space center

In a lighter mood, Ed Schneider gives a "thumbs-up" after his last flight at the Dryden Flight Research Center on September 19, 2000. Schneider arrived at the NASA Ames-Dryden Flight Research Facility on July 5, 1982, as a Navy Liaison Officer, becoming a NASA research pilot one year later. He has been project pilot for the F-18 High Angle-of-Attack program (HARV), the F-15 aeronautical research aircraft, the NASA B-52 launch aircraft, and the SR-71 "Blackbird" aircraft. He also participated in such programs as the F-8 Digital Fly-By-Wire, the FAA/NASA 720 Controlled Impact Demonstration, the F-14 Automatic Rudder Interconnect and Laminar Flow, and the F-104 Aeronautical Research and Microgravity projects.

This photo shows a head-on view of NASA's SR-71B, used for pilot proficiency and training, on the ramp at the Air Force's Plant 42 in Palmdale, California, shortly before delivery to the Ames-Dryden Flight Research Facility (later, Dryden Flight Research Center) at Edwards, California. NASA operated two of these unique aircraft, an SR-71A, for high-speed, high altitude research, and this SR- 71B pilot trainer for most of the decade of the 1990s. The "B" model is special because of its raised rear cockpit, which provided a second pilot position so a trainer and an experienced pilot could both see what was going on during flights. The SR-71 was designed and built by the Lockheed Skunk Works, now the Lockheed Martin Skunk Works. Studies have shown that less than 20 percent of the total thrust used to fly at Mach 3 is produced by the basic engine itself. The balance of the total thrust is produced by the unique design of the engine inlet and "moveable spike" system at the front of the engine nacelles, and by the ejector nozzles at the exhaust which burn air compressed in the engine bypass system. Data from the SR-71 high speed research program will be used to aid designers of future supersonic/hypersonic aircraft and propulsion systems, including a high speed civil transport.

The NASA SR-71A successfully completed its first cold flow flight as part of the NASA/Rocketdyne/Lockheed Martin Linear Aerospike SR-71 Experiment (LASRE) at NASA's Dryden Flight Research Center, Edwards, California on March 4, 1998. During a cold flow flight, gaseous helium and liquid nitrogen are cycled through the linear aerospike engine to check the engine's plumbing system for leaks and to check the engine operating characterisitics. Cold-flow tests must be accomplished successfully before firing the rocket engine experiment in flight. The SR-71 took off at 10:16 a.m. PST. The aircraft flew for one hour and fifty-seven minutes, reaching a maximum speed of Mach 1.58 before landing at Edwards at 12:13 p.m. PST. "I think all in all we had a good mission today," Dryden LASRE Project Manager Dave Lux said. Flight crew member Bob Meyer agreed, saying the crew "thought it was a really good flight." Dryden Research Pilot Ed Schneider piloted the SR-71 during the mission. Lockheed Martin LASRE Project Manager Carl Meade added, "We are extremely pleased with today's results. This will help pave the way for the first in-flight engine data-collection flight of the LASRE."
