NASA Goddard Space Flight Center is home to the nation's largest organization of combined scientists, engineers and technologists that build spacecraft, instruments and new technology to study the Earth, the sun, our solar system, and the universe.

Designed by Northrop in the early-1970s, the YA-9 Ground Attack Aircraft was developed in response to a request by the US Air Force for a rugged, close air support aircraft capable of destroying the heaviest Soviet tanks and armored vehicles. Envisioned as a "flying tank" the A-9 was designed with low-level survivability in mind. With redundant flight control systems and aluminum alloy armor 1.25 to 2.5 inches thick protecting all vital areas, the A-9 could withstand multiple direct hits from Soviet 23mm anti-aircraft cannons. The twelve under-wing weapons pylons could carry nearly every ordnance combination in the Air Force inventory.
Unfortunately for the A-9, its competitor in the ground attack selection was the now legendary Fairchild Republic A-10 Thunderbolt II, possibly the greatest ground attack aircraft ever designed. The Air Force awarded the contract to Fairchild-Republic.
Only two YA-9A prototypes were built by Northrop Aviation, serial numbers 71-1367 and 71-1368. Together they completed 123 flights, totaling 146.0 flight hours during the ground attack aircraft selection. After the decision, the U. S. Air Force had neither use for nor interest in either of the two YA-9As; they were transferred to the NASA Dryden Research Center before being completely retired from service on April 2, 1973.
Both YA-9A's still exist today. March Field Air Museum's 71-1368 is on display; its sister ship is at Edwards AFB. The March Field Air Museum received its YA-9A in 1981 as a loan from the NMUSAF.
NASA's Operation IceBridge is flying its summer Arctic land ice campaign in Greenland, continuing its measurements of the Greenland Ice Sheet and its outlet glaciers.

The RADAR support structure, built in the early 1970s for the new High Accuracy Instrumentation RADAR (HAIR) had to be located & build very precisely, and was the one part of the facility that really incorporated heavy-duty construction techniques.
We'll visit that steel shed in the background soon.
Cada vez que una misión sale de Cabo Cañaveral, esta gigantesca estructura con el único cometido de transportar el combustible necesario para vencer la fuerza de la gravedad le acompaña, siendo deshechada por el camino a medida que va quedando vacÃa.

NASA Gulfstream I (G159) N10NA
The access I had to the Prestwick apron in 1975 and 1976 could only be a dream today. The Scottish airport had a steady stream of spectacular visitors and, following the qualified success of my Madagascan C172s, I am marking the 50th anniversary of my Scottish period with more scans. Unfortunately, I was much less fastidious with my notes in those days but I hope someone will be stirred by my offerings.
