A NASA CV-990, modified as a Landing Systems Research Aircraft (LSRA), is 
serviced on the ramp at NASA's Dryden Flight Research Center, Edwards, 
California, before a test of the space shuttle landing gear system.
The space shuttle landing gear test unit, operated by a high-pressure 
hydraulic system, allowed engineers to assess and document the performance 
of space shuttle main and nose landing gear systems, tires and wheel 
assemblies, plus braking and nose wheel steering performance. The series of 
155 test missions for the space shuttle program provided extensive data 
about the life and endurance of the shuttle tire systems and helped raise 
the shuttle crosswind landing limits at Kennedy

Isn't the CV-990 the same type aircraft that collided with a P-3 on approach 
to Moffett Field in the early 70's?  There was only one survivor from that 
crash and he got run over by a crash truck while unconscious on the ground.

In a left-hand pattern west of the air station. There are two parallel 
runways at NAS Moffett Field, California 32L and 32R. Only the right runway 
was equipped for Moffett Field, located 30 miles south of San Francisco, 
California, was a busy facility in 1973. The air station was the 
headquarters for all US Navy patrol activity in the Pacific, and in this 
role it was home to many patrol squadrons flying the Lockheed P-3Orion. NAS 
Moffett Field California was also home to NASA's Ames Research Center, which 
at the time operated a wide variety of research and experimental aircraft. 
On April 12, 1973, a Navy P-3C and a Convair 990 operated by NASA collided 
while on final approach to Moffett field, killing 16 of the 17 people aboard 
the two aircraft.
The Navy P-3C, bureau number 157332, was assigned to Patrol Squadron 47 
(VP-47). It had departed NAS Moffett Field, California for a training flight 
approximately five and a half hours prior to the accident. LT Stephen A. 
Schwarting was in command of the P-3,along with two pilots in training, a 
flight engineer, and two observers. LT Schwarting had been a Navy pilot for 
five years, and at age 29 he had logged 2014 flight hours, 1014 of those in 
P-3aircraft.
During the first part of the training flight, the P-3 operated over the 
ocean off of Big Sur, California. The P-3 and its crew then returned to NAS 
Moffett Field, California to practice approaches and landings. At the time 
of the accident, the P-3 crew had been flying approaches to touch-and-go 
landings on runway 32L for about an hour and a half, circling instrument 
approaches, but on the day of this collision the weather was fair and the 
visibility was excellent.
While the P-3 was flying approaches on runway 32L, a Convair 990 operated by 
NASA was south of NAS Moffett Field, California flying a straight in 
approach. The Convair 990 was a flying laboratory, nicknamed Galileo, which 
was operated in conjunction with scientific programs at Ames Research 
Center. The Convair 990, N711NA, was delivered to NASA in 1964 and was one 
of four 990 models operated by NASA over the years.
On the day of the accident Galileo was returning from a two hour flight over 
Monterey Bay to test a newly installed system for surveying migratory sea 
mammals. In past experiments Galileo had chased the 1967 solar eclipse, 
taken astronomers aloft to study comets, and it had last been used in a 
joint Soviet-American survey of the Bering Sea. The pilot of Galileo was 
James P. Riley, age 28. There were a total of eleven men on board Galileo: 
seven were NASA employees, Northrop, Inc. employed two and Teledyne, Inc 
employed two.
Galileo's pilot first contacted the NAS Moffett Field, California tower at 
1446, stating that he was ten miles south of the air station and requesting 
a straight-in approach. At that time the air traffic controller instructed 
Galileo's' pilot to approach runway 32R and to contact the tower when he was 
seven miles south of the air station. There were other aircraft in the 
pattern at the time, and shortly after his exchange with Galileo, the 
controller stated to another aircraft that there were numerous P-3's in left 
traffic for runway 32.
At 1448, the pilot of the P-3 contacted the tower and stated that he was 
turning base with wheels down, for touch and go. The controller acknowledged 
that transmission and instructed the pilot to continue for the left side. 
Seconds later, Galileo's pilot contacted the controller and stated that he 
was seven miles south of the air station. The controller acknowledged the 
transmission from Galileo, and after an exchange with another aircraft, the 
controller instructed the Galileo to continue for the right side..
At 1449, the pilot of Galileo contacted the tower and stated gear down and 
locked. The controller replied by informing the pilot of the wind speed and 
direction, and then without explanation he stated that Galileo was cleared 
to land 32L. The pilot of Galileo did not question the change in runway 
clearance, but acknowledged it by stating 32L, thank you. A few moments 
later the air traffic control transcript contains a transmission that is 
probably from LT Schwartings P-3, stating touch and go on left side. The 
tower acknowledged this transmission by instructing the P-3 to continue. At 
this point the two aircraft began to converge on the left runway approach.
At 1450, the air traffic control transcript contains an unidentified 
transmission that states "Tower you got that" followed by a second, garbled 
transmission. The controller replied to these two transmissions by saying 
"go around, go around, weave". The controller then instructed all aircraft 
in the pattern to climb and maintain 1500ft. By that time the P-3 and 
Galileo had collided and crashed together about one half-mile south of the 
runway.
At the time of the collision Galileo was apparently above the P-3, 
descending on a converging path. According to the official Navy 
investigation, the fuselage at the base of the P-3s vertical fin showed 
evidence of two tire marks that matched the dual nose tires of Galileo. In 
addition to that, three pieces of the P-3s fuselage frame were found 
embedded in the nose wheels of Galileo.
According to eyewitnesses, the P-3 pulled up sharply in the moment before 
the collision, perhaps in an evasive action. Galileo struck the upper aft 
fuselage of the P-3 and the two aircraft crashed entangled on the l2th tee 
of the Sunnyvale Municipal Golf Course. A large fire immediately engulfed 
the two wrecked aircraft. Although there were people playing golf nearby, 
miraculously no one on the ground was hurt.
The crash scene quickly became chaotic. The two aircraft crashed just 200 
yards from the Bay shore Freeway, and drivers left their cars to scale the 
fence and rush to the burning wreckage. Golfers, and people from nearby 
office buildings who had seen the crash also swarmed around the site. The 
large number of onlookers made access difficult for the crews responding 
from NAS Moffett Field, California and Sunnyvale. At the time of the crash a 
group of firemen were watching a demonstration of a jaws of life rescue 
device at the Mountain View training center. When they saw the crash they 
loaded the rescue equipment and went to the scene.
All of the sixteen men who were killed died in the crash or in the fire that 
followed it. The one survivor was Petty Officer Third Class Bruce N. 
Mallibert, who was an observer on the P-3. One of the golfers at the crash 
scene found Mallibert seriously injured and lying unconscious outside of the 
wreckage, and mistakenly thought that he was dead. He covered Malliberts 
body with a parachute, but soon after that a fireman checked Mallibert and 
discovered that he was still alive. Mallibert was lucky to have survived the 
crash, but he would escape death a second time minutes later. While the 
parachute covered him a fire truck drove over him, unaware that he was 
underneath. Miraculously, the trucks wheels missed Mallibert on both sides. 
He was taken to a nearby hospital where he remained in critical condition 
for many days.
This crash renewed calls for the Navy to leave NAS Moffett Field, California 
, and several local members of Congress called for a halt to flying from 
Moffett in the days following the crash. While there had been a large number 
of crashes around the air station when it was a home to fighters and attack 
aircraft in the 1950s, the safety record of the P-3 operations was 
excellent. This collision was the first and only crash of a P-3 near the 
airfield between the early 1960s and 1994 when the Navy decommissioned NAS 
Moffett Field, California
With the loss of Galileo, NASA lost a unique research asset in addition to 
losing several of the scientists who had helped to develop the flying 
laboratory and its experiments. Many of the programs that were to use 
Galileo were either delayed for years or were cancelled completely following 
the crash.
This accident apparently occurred because of a simple mistake in air traffic 
control procedures. Neither of the aircraft suffered mechanical problems, 
the weather was excellent, and the crew aboard each aircraft was well 
trained and experienced. Sixteen men and two valuable aircraft were lost, 
but hopefully future accidents were averted by an increased awareness of the 
factors that caused this tragedy.
According to eyewitnesses, the P-3 pulled up sharply in the moment before 
the collision, perhaps in an evasive action. Galileo struck the upper aft 
fuselage of the P-3 and the two aircraft crashed entangled on the l2th tee 
of the Sunnyvale Municipal Golf Course. A large fire immediately engulfed

Now that's some research.  Thanks for the added info.  I knew if I asked a 
question here that someone would know the answer.

I worked at NASA Ames Research Center a few years, 1974-1976 in high 
school and college work experience programs. They had a 990 mounted on a 
pair of cradles outside the hangers, wings and tail torn off. I was told 
it had been damaged in a hard landing the Philippines. A few of us 
students were selected to cap the torn wings and tail with smooth sheet 
metal, to clean up the appearance. We were told it was going to be set 
up to train researchers to work in an aircraft setting.
I noticed while browsing Ames via Google Earth, that fuselage is gone.
Anyone know what happened to it?
We had fun that summer, crawling around the belly, and even up into the 
center fuel tank. Man, is that a tight squeeze!
Ah, stupid and immortal youth....
Most memorable moment was finding a small hatch near the back. Reaching 
up with a length of aluminum angle, we popped it open to find an open 
round fitting and a t-handle. Being stupid kids and curious, we 
fashioned a lasso and got it around the t-handle and yanked. Well, 
someone had been using the aft restroom, and luckily for us, there was 
just enough advance gurgling that we -barely- escaped the stream as the 
aft toilet reservoir emptied itself on the ground...
I also got to do a bit of work in the flying CV990 they operated then, 
working with the journeymen. Ah, those were the days....

Bruce did survive, though ended up wheelchair bound for life. He married 
my sister's best friend, Kathy Keehan. Kathy succumbed to cancer a few 
years ago. I never met him myself, and I don't know anything of his 
religious beliefs prior to the accident, but post crash he was and is, a 
very devout Christian.
I lived about a mile from the crash site at the time and remember it 
very well.

My first real job in '58-9 was as a high school student "engineering
assistant"  for Convair in SD, mostly at Convair Astro out on Kearney
Mesa. They were building the F106 in the long plant along the highway,
on the east end of Lindbergh Field. The 990s were being assembled in
the big hangar on the south side of the airport road, across from
Ryan, which is now the commuter aircraft terminal. That hangar is now
Coast Guard.
The 880 and especially 990 had efficiency and performance advantages
over the Boeing and Douglas birds, but they were late to the game, and
developed without urgency. 
Occasionally we'd have a B-36 come in ... really filled up the small
and short Lindbergh runway.
