Pilot and Paresev 1 preparing for a landing on the Rogers dry lakebed in 1962 at Edwards Air Force Base, California. The flight program began with ground tow tests. Several tows were made before liftoff was attempted to check the control rigging and to familiarize the pilot with the vehicle’s ground stability. As the pilot’s confidence and experience increased, tow speeds were also increased until liftoff was attained. Liftoff was at about 40 knots indicated airspeed (kias).

After initial ground-tow flights of the M2-F1 using the Pontiac as a tow vehicle, the way was clear to make air tows behind a C-47. The first air tow took place on 16 August 1963. Pilot Milt Thompson found that the M2-F1 flew well, with good control. This first flight lasted less than two minutes from tow-line release to touchdown. The descent rate was 4,000 feet per minute.

EDWARDS, Calif. – Against a setting sun, space shuttle Endeavour undergoes recovery operations on Edwards Air Force Base in California after its landing. The orbiter convoy normally begins recovery operations in earnest about two hours before the shuttle is scheduled to land. Specially designed vehicles or units and a team of trained personnel “safe” the orbiter and prepare it for towing. Purge and Coolant Umbilical Access Vehicles are moved into position behind the orbiter to get access to the umbilical areas. The flight crew is replaced aboard the orbiter by exchange sup¬port personnel who prepare the orbiter for ground tow operations, install switch guards and remove data packages from any onboard experiments. After a total safety downgrade, vehicle ground personnel make numerous preparations for the towing operation, including install¬ing landing gear lock pins, disconnecting the nose landing gear drag link, positioning the towing vehicle in front of the orbiter and connecting the tow bar. The decision to land Endeavour at Edwards was made due to weather concerns at NASA's Kennedy Space Center in Florida. In the 52nd landing at Edwards, Endeavour touched down at 4:25 p.m. EST to end the STS-126 mission, completing its 16-day journey of more than 6.6 million miles in space.

Atlantis arrived at Kennedy Space Center atop the SCA on July 3 after a three-day, cross-country flight due to fuel stops and weather delays. Touchdown was at 8:27 a.m. EDT. Atlantis landed at Edwards Air Force Base in California on June 22 to end mission STS-117. Photo credit: NASA/Jack Pfaller.

An aerial closeup view reveals the ongoing construction of an $8 million Reusable Launch Vehicle (RLV) Support Complex at Kennedy Space Center. At right is a multi-purpose hangar and at left a building for related ground support equipment and administrative/ technical support. The complex is situated at the Shuttle Landing Facility. Near the top of the photo can be seen the tow-way. The RLV complex will be available to accommodate the Space Shuttle; the X-34 RLV technology demonstrator; the L-1011 carrier aircraft for Pegasus and X-34; and other RLV and X-vehicle programs. The complex is jointly funded by the Spaceport Florida Authority, NASA's Space Shuttle Program and KSC. The facility will be operational in early 2000

Atlantis is towed from KSC’s Shuttle Landing Facility to the Orbiter Processing Facility. Atlantis returned from California atop a Shuttle Carrier Aircraft (seen in the background, left) after its Feb. 19 landing at Edwards Air Force Base, concluding mission STS-98. The ferry flight began March 1; unfavorable weather conditions kept it on the ground at Altus AFB, Okla., until it could return to Florida. In the Orbiter Processing Facility, Atlantis will be prepared for mission STS-104, the 10th construction flight to the International Space Station, scheduled to launch June 8

NASA's Orion spacecraft splashed down in the Pacific Ocean after its first flight test atop a Delta IV Heavy rocket from Space Launch Complex 37 at Cape Canaveral Air Force Station in Florida. U.S. Navy divers in Zodiac boats prepare to recover Orion and tow her in to the well deck of the USS Anchorage. NASA's Orion spacecraft completed a two-orbit, four-and-a-half hour mission to test systems critical to crew safety, including the launch abort system, the heat shield and the parachute system. The Ground Systems Development and Operations Program is leading the recovery efforts.

NASA’s Operation IceBridge collected some rare images on a flight out of Punta Arenas, Chile on Nov. 5, 2014, on a science flight over western Antarctica dubbed Ferrigno-Alison-Abbott 01. Following a routine calibration pass over Punta Arenas airport, the NASA DC-8 overflew the USS Constellation which is being towed for demolition after 53 yeas of service. The crew then snapped a few shots of a calving front of the Antarctic ice sheet. This particular flight plan was designed to collect data on changes in ice elevation along the coast near the Ferrigno and Alison ice streams, on the Abbot Ice Shelf, and grounded ice along the Eights Coast.
