(Project OXCART, A-12, Pilot Training)
By: CIA PROJECT PILOT KEN COLLINS
Most are familiar with the military term “R&R”
(Rest & Recreation). For the family it has a totally different connotation.
For them it reassignment and relocation and a lot of work. The Air Force
life had many positive aspects and usually they benefited both the Air
Force and the military member and his family. The squadron assigned you
a fellow officer to assist you and your family in getting settled and familiar
with the new base and the local area. Housing was essential for the family
prior to settling into the new job. This job was as a civilian working
as a flight test pilot/consultant to Hughes Aircraft Company, but they
only assisted you with the job administration. For housing and the family
I was on my own.
Coming
from little country Sumter, South Carolina to a mega-metropolitan area
like Los Angeles for the first time was something else. Jane and I and
our four children departed Sumter, SC via Washington D.C. making relative
“pit stops” in Memphis, Tennessee and San Angelo, Texas, and from there
to Long Beach, California. This was the only city in California that I
had ever visited. I had flown to the Long Beach airport in 1951 in a B-25
Trainer out of Vance AFB, OK with my instructor, Captain Cook, and my flight
classmate, Chuck Costantino. We were there two days and flew back to Oklahoma.
The family and I were there only two days, also. After talking to Walt Ray,
another project pilot, we moved to the San Fernando Valley. This at
the suggestion of Clay Lacy, a pilots training classmate and friend of Walt
Ray. Clay Lacy was then a pilot for United Airlines and now owns Clay Lacy
Charter, a very successful air charter company at Van Nuys Airport. Getting
the family settled and feeling secure was important to the program. They
knew that the project pilots were going to be out of touch generally from
Monday through Friday and some weekends. If there was a serious problem,
my wife had a telephone number to call any time and request that I call.
The return call could be immediate or in one or two days, depending on the
your schedule and location. My wife knew that I was on a very special operational
flying assignment, but not my location, what I was flying, my sponsor or
my associates other than the other project pilots. Since I now had the family
in place, I was ready to dedicate myself to the project.
I began
the flying training by rechecking out in the F-101. Since I had already
had over 1000 flight hours in the RF-101A, C and B (Trainer) as an combat
qualified crew member and a Flight Instructor less than three months before,
the checkout in the F-101 and Air to Air Refueling was completed
in a short time. All flying was accomplished in accordance with current
Air Force Standardization and Evaluation regulations. All the staff and
operations personnel were permanent party Air Force. Colonel Doug Nelson
was the Operations Officer and Major Ray Haupt was the Standardization &
Evaluation Officer.
The project
pilots studied the existing A-12 procedures documents, reviewed
the systems with aircraft systems engineers and the Lockheed test pilots
and got all of the cockpit time possible. It is important to this
phase of the program to point out that there was very few established, tested
data and procedures. Kelly Johnson repeatedly said that this was a
truly experimental test program. The existing systems were new and untried.
Changes were being made daily with the completion of each test flight; procedures were developed in flight and during the debriefings. Each flight was critically reviewed by the Project pilots, the systems engineering staff and the Lockheed test pilots. he A-12 flight training began with a 3 ore 4 flights in the A-12 Trainer, which had P & W J-75 engines with afterburners. The cockpit and flight systems were basically the same as the other A-12s, but the trainer would only get out to Mach 2+. There was no simulator, so the trainer was the best available and it was a good trainer. The takeoffs and landings were very similar to the operational A-12, as was the aerial refueling. I wanted to insure that I got all the trainer flight time possible in preparation to my first flight in the A-12 (single cockpit with J-58 engines). My first A-12 Trainer flight was on 6 February 1963. Bill Skilar was the first project pilot to fly the Trainer on 4 February 1963. Walt Ray followed me on 10 February 1963. Lon Walter some time after that. Lon opted out of the program shortly after he started flying the J-58 A-12 aircraft.
The most
critical event that the Trainer could not prepare you for was the inlet
unstarts, because it didn’t have spikes (variable geometry inlet) and could
not get out to Mach 3. Other important points to make at this juncture:
1- The A-12 did not have aft bypass doors. 2- did not have spike
and door position indicators. 3- only had spike/door restart switches. 4-
the fuel controls were unreliable. 5- the inlet controls were unreliable.
To repeat, everything was very dynamic, changing all the time, usually to
the best.
As soon after the A-12 Trainer checkout as possible, we were put
on the A-12 schedule.
Every flight was different with the exception that every flight
had multiple inlet unstarts.
When you began the climb and acceleration out to 80,000 feet (Flight
Level 800 or FL 800) and Mach 3, you were certain that there would be
a ”popped shock” and an unstart between 2.5 Mach (FL 400 to FL 500) and
2.9 Mach (FL 600 to FL 700). You never knew the extent. All unstarts were
sever and serious in the beginning. Since we only had a toggle switch for
each inlet (no inlet position indicators until much later) you were reacting,
usually too late, to an unstart in progress. An unstart of an inlet “popped”
the shock out of the throat of the inlet immediately stopping the air flow
through that inlet, compressor stalling the engine and causing an
afterburner blowout both of which was essential to your acceleration and
retaining altitude. At this phase of the test program you were only guessing
which system unstarted, left or right. For any hope of restarting the inlet
and continued acceleration, you hit both inlet toggle switches immediately.
By making a quick guess you reactivated that inlet toggle hoping that you
could catch it before the unstart compressor stalled the engine and blew
out the afterburner. Even after guessing right, you were usually too late,
because it all happened in a nanosecond. After the unsuccessful attempt
to get an immediate restart, you were in for head knocking. (Your
helmet was knocking rapidly against the canopy), rapidly decelerating, shuttering
dive toward the ground. You weren’t concerned about the inlets at this
point. Your primary efforts were toward getting the engines restarted, because
the severity of the initial inlet unstart (it is now called an aerodynamic
disturbance by the engineers), the aircraft was placed in a hard yawed causing
the other inlet to unstart, the other engine to compressor stall and the
other afterburner to flame out, leaving you with a more serious problem and
very few options. You had to get one or more engines started. Reflecting back
to those days, we always got at least one engine running. The most serious
problem occurred when the TEB probes started “coking”(Getting a chemical residue
buildup on the engine/afterburner starting TEB probe restricting the flow
of the TEB, which ignited the engine and/or the afterburner for start. We
had a lot of other mechanical and electronic system problems throughout the
program, but none as big as the inlet unstarts.
There isn’t
an A-12 pilot who hasn’t experienced the severity of the inlet unstart
and knew that he would have to “punch” out. This was an unthinkable thought
for every A-12 pilot. He also experienced what Ernest Gann stated that “Faith
Is The Hunter”. Most of us needed a lot of luck and Someone up there looking
out for you.
I was scheduled
for a flight test mission to perform subsonic engine test runs, because
we were having a lot of problems with engine fuel controls during acceleration
and cruise. Jack Weeks was scheduled as my F-101 Chase pilot. The date
was 24 May 1963. Take off and initial cruise (25,000 Feet Altitude) was
routine. I made the planned right turn to 180 degrees and climbed to 27,000
feet to stay out of the building cloud formations. During these missions
the chase plane was to stay close enough to observe the engine nacelles
and the afterburner areas, but far enough away to maintain safe flight.
The F-101 had a historical pitch-up problem, if it got too slow
in flight. As we continued south in the Windover Danger Area (Northwest
of the Great Salt Lake) I entered an area of heavy cumulus cloud formations.
My chase moved in to keep visual contact. Minutes later, Jack signaled
that we were getting too slow for the F-101. All of A-12 instruments (airspeed,
altitude) were giving normal indications. Jack signaled that he could
not stay with me. I waved him off and he cleared to my right and disappeared
into the clouds.
I dedicated
all my efforts to determining what the real problems were. I engaged
the autopilot and reviewed all of the instruments and systems. There
was no observable failures or abnormal indications. I then disengaged
the autopilot maintaining my planned airspeed and 30,000 feet altitude.
In a matter of seconds all hell broke out. Without any noticeable change
of aircraft attitude or speed the altimeter was rapidly “unwinding” indicating
a rapid loss of altitude and the airspeed indicator was also “unwinding”
displaying a rapid loss of airspeed. In the heavy clouds with no visual
references and with what felt like a solid platform under me, I advanced
the throttles attempting to stop the indicated loss of airspeed, but with
no obvious results. At this point I could not assumed that any of my flight
or engine instruments were providing correct data and I was right. Without
any warning the A-12 pitched up and went into a flat inverted spin.
NOTE: The
Oxcart Story stated that I was “on a routine training flight” and that
I “recognized an erroneous and confusing air speed indication and decided
to eject from the aircraft”. This was written by a number of people who
combined their non-aviation knowledge and experience in a quick effort
to put a paper together. There were no project pilots who would casually
“decide to eject” because of a confusing airspeed indication. Our dedication
to the program, to the A-12 and to flying was much deeper than that.
Realizing
that I had no effective controls and that the aircraft was unrecoverable
from this flat inverted spin and that I had no true indication of my actual
altitude, it was time to eject. I could have been much lower and over
higher mountains, which would put me dangerously close to the ground or
hill tops. I closed my helmet visor, grabbed the ejection “D” ring between
my legs, firmly pushed my head against the ejection seat headrest and pulled.
The aircraft canopy instantly flew off, the boot stirrups snapped back
into the seat retainers locking my feet securely for the ejection and the
rocket jet charge fired shooting me down and away from the aircraft. The
man/seat separator worked great. Shortly after separating from the seat
my “chute” opened. I looked up to confirm that I did indeed have a chute
(This was my first ejection). I then looked down at the ground to get a
general idea of the terrain where I would land. At that very moment the
“chute” broke away, separating from my parachute harness. I knew that my
luck had just run out! There was momentarily a quieting sensation; a pause
in my life. Just as suddenly, this beautiful 35 feet canopy blossomed quickly
slowing my descent (The A-12 parachute was made with two parachutes. A smaller
drogue chute, that deploys shortly after ejection and seat separation. Its
primary purpose is to slowly decelerate the pilot ejecting at high speeds
and altitudes. The main parachute was 35 feet in diameter to compensate
for the extra weight of the pressure suit. If the main chute deployed at
high altitude and excessive speeds, the pilot would be killed from the
instant deceleration.) When I ejected, I did not know what my altitude
was. After the ejection I was just happy that I had a parachute and
was out of the clouds. I had separated safely from the aircraft. When descending
through 15,000 feet, the drogue chute is programmed the separate and the
main chute is scheduled to deploy. At that moment I truly thought that my
parachute was gone.
During my
descent I saw the A-12 spiraling toward the ground and then a large black
column of smoke and flames behind a hill. I had time to “look around”.
I saw a road miles to the right and a lot of rough terrain covered with
rocks and sage. As a got closer to the ground, I assumed the parachute
landing position with feet together and knees bent. I hit to ground and
rolled on my right side into a standing position. I immediately released
the riser safety clips and collapsed the chute. You keep the parachute
canopy for survival. I was in the middle of a hilly desert with little
prospect to be rescued soon. My chase plane (Jack Weeks) did not know where
I was and because of the program classification, we did not maintain radio
contact with the base operations. I began collecting all of my flight checklist
pages, which broke loose during the ejection, and any other aircraft items
lying around. Much to my amazement I saw a pickup truck bouncing across
the rocks coming toward me with three men in the cab. When they stopped,
I saw that they had my aircraft cockpit canopy in the truck bed. They asked
me if I wanted a ride. They said that they would take me over to my airplane.
I told them that it was an F-105 fighter with a nuclear weapon onboard. They
got very nervous and said that if you’re going with us get in quick, because
they were not staying around here. There were four of us in the truck cab.
I asked them to drop me off at the nearest Highway Patrol Office, which
was in Windover, Utah. I thanked them and that was the last I was of them.
I made my “secret” phone call. The base sent a Lockheed Constellation
loaded with security people and aircraft engineers in less than two hours.
Kelly Johnson’s jet arrived behind the “Connie” to pick me up. Our flight
surgeon and I flew directly to Albuquerque, New Mexico to the Lovelace Clinic
for my physical checkup.
An intense
accident investigation was conducted. I submitted to sodium penathal to
confirm all my statements relating to the flight and the accident. The
person who solved the true technical causes (inadequate pitot tube- thus
the Rosemont Probe, failed air data computer) of the accident was Norm Nelson, a dedicated government engineer and a fine, caring man, who
later became Vice President of the Skunkworks. As always, the initial belief
is that there was Pilot Error, fortunately the real causes of the accident
were discovered and corrected. Ten years after the accident, I received
a package in the mail. Unwrapping it, I found a shadowbox frame with the
“D” ring mounted inside with the inscription to Ken Collins "A
Friend In Need”. It was my ejection “D” ring from the A-12 and was sent to
me by Keith Beswick, a Lockheed engineer on the Oxcart program.
This personal
rapport was typical of the relationship during the program between the
project pilots and all of the Lockheed personnel from Kelly Johnson down.
The Air Force
Personnel were no less professional and supportive. The Oxcart Program
will remain in the minds and hearts of all those who were in the program.
I want to make a special note to the honor and memories of Walt Ray and
Jack Weeks. Both were killed while performing their duties as A-12 project
pilots and to this I respectfully keep in my memory their wives, Diane
Ray and Sharene Weeks, who lived through the worries and their personal
losses.
Of those
who were in the Oxcart Program from the beginning through the overflights
the last A-12 flight I want to commend all of you. They were Colonel Bill
Skilar (Killed after retirement in his racing aircraft), Mele Vojvodich,
retired Major General in San Antonio, Texas, Denny Sullivan, retired Brigadier
General in Colorado Springs, Colorado, Jack Layton, retired Colonel in
Utah and Frank Murray, retired Lt. Colonel in Carson City, Nevada. They
all were “friends in deed”.
The one
person that I owe the most gratitude and appreciation for her perseverance
in the face of the unknown, support of me and our children, understanding
when I could tell her nothing and her love, is my wife, Jane Bingham Collins.
