Blackbird crews flew to the edge of space, literally faster
than a speeding bullet. Even on its way to retirement, the SR-71
set speed records
Almost Astronauts
By Greg Kline
THEY fit somewhere between aviators and astronauts, these men
who flew the SR-71 Blackbird and its Lockheed siblings, the A-12
and the YF-12. They flew almost to the border of space, so high
they could see the curvature of the Earth. Above 80,000 feet,
nearly sixteen miles high, the sky overhead was deep blue, almost
black, and stars were visible at noon.
They flew so fast they could literally pass a speeding bullet.
Cruising speed exceeded 2,100 miles per hour, three times the
speed of sound. They were armed only with cameras and radar--and,
of course, that blinding speed. No enemy aircraft ever caught
a Blackbird, let alone shot one down.
"It's sort of a fraternity, and not a very large fraternity,"
says retired Maj. Gen. Frank Elliott, one of these almost-astronauts.
"There was only one outfit of SR-71s. There are not that
many people who have flown it."
On the lapel of his sport coat, Elliott, sixty-five, wears
his "fraternity" pin, a tiny pewter model of the SR-71
with a red "3 +" embossed on it. "You have to have
flown in excess of Mach 3 to get that pin," he explains.
He's a silver-haired man who retains his military posture and
sometimes lapses into a Chuck Yeager-like drawl common to many
pilots of hot airplanes.
The SR-71 could well have flown into the twenty-first century, contends
Elliott, and many other former crew members agree. When the Air Force retired
the plane this year and shipped the dozen or so remaining
Blackbirds to museums and to NASA, obsolescence wasn't the reason. It still
holds world records for speed over a straight course (2,193 mph) and altitude in
horizontal flight (85,069 feet). In March, the aircraft shattered the Los
Angeles-Washington, D. C., speed record, making the trip in sixty-eight minutes,
seventeen seconds, on its way to its new home, the National Air and Space
Museum.
What doomed the SR-71 was money--or, rather, the lack of it.
The plane was expensive to operate ($200 million to $300 million
each year; $18,000 per hour for special fuel alone), and an existing
network of satellites could perform its photographic mission.
The cost to operate the fleet of SR-71s equaled the operating
costs of two fighter wings, and their data could be obtained elsewhere.
Born in the Black
Frank Elliott had his eyes on the Blackbird early, when the
plane was still "in the black" and unknown to all but
a select few. He saw it well before the day that President Lyndon
Johnson, trying to deflect soft-on- defense charges from challenger
Barry Goldwater, raised eyebrows by publicly acknowledging the
SR-71's existence during the 1964 Presidential campaign.
In 1962, the first of the supersecret spy planes--then designated
A-12--were flying from the classified Groom Lake, Nev., testing
facility, dubbed "the ranch." Elliott was commanding
the 465th Strategic Aerospace Wing at Beale AFB, Calif. Specially
modified KC-135 tankers from his unit carried out the in-flight
refueling of the fledgling Blackbirds. The tanker pilots went
through security checks before being assigned to the mission.
Some crew members worked behind screens that prevented them from
seeing what kind of plane was being refueled.
"We were doing this for two years before the airplane
came out of the black," says Elliott, now retired and working
as the economic development coordinator for the municipality of
Rantoul, Ill. "By that time, I wanted to fly it so bad I
could taste it "
He would wait six more years for the chance. It finally came
in 1970 when, after a tour of duty at the Pentagon, Elliott was
named commander of the 14th Strategic Aerospace Division at Beale
AFB. By then, the SR-71s, now fully operational and flying missions
over Vietnam and other world hot spots, were based there as part
of the division's 9th Strategic Reconnaissance Wing.
Today, pictures and paintings of planes Elliott flew over a
thirty-year Air Force career line the walls of his office: B-24
and B-52 bombers, F-4 Phantom fighters. The largest display is
a montage depicting SR-71s.
In one head-on photo of a parked Blackbird, the twin tail fins,
bulging engine nacelles, and single eye of its front cockpit canopy
give the plane the appearance of an angry insect. Another shot,
looking down on the plane in flight, reveals its futuristic lines.
In his biography, former Soviet pilot Lt. Viktor Belenko, who
defected in 1976, writes about (then) top-of-the-line Russian
MiG-25 fighters attempting to intercept SR-71s operating along
the Soviet Union's east coast. The Blackbirds taunted and toyed
with the MiG-25s, reports Lieutenant Belenko, "scooting up
to altitudes the Soviet planes could not reach and circling leisurely
above them, or dashing off at speeds the Russians could not match."
Legend has it that the Blackbird could photograph the numbers
on a license plate from an altitude of 80,000 feet. The Air Force
never confirmed that, although it has admitted that one could
probably identify a person from some of the SR-71's pictures.
Elliott is certainly not alone when he says that "a lot
of tears were shed" over the demise of the SR-71. There is
a mystique about these planes. For the public, it is a mystique
built on flying speed, altitude, and the secrecy that shrouded
the Blackbird. For the crew members, it likely comes from being
almost astronauts.
Elliott recalls undergoing "an astronaut physical"
before being allowed to pilot the Blackbird. Preparations for
an SR-71 flight in many ways resembled the launch process for
a space mission.
Breathing Pure Oxygen
The plane's two-man crew, a pilot and reconnaissance systems
operator, ate special meals before a flight and breathed pure
oxygen. The oxygen purged nitrogen from their bloodstreams and
prevented the high-altitude problem of severe cramping. They also
underwent an abbreviated physical before being helped into their
helmeted flight suits, garments nearly the same as those worn
by early astronauts.
A seven-person ground crew strapped them into the SR-71 and
gave the plane a detailed preflight examination. A truckload of
crew members trailed it down the runway on takeoff, visually confirming
that all systems were go. Then they were off ("You really
get a kick in the tail when you start," says Elliott) and
up and up and up, leaving a trail of shock diamonds and sonic
booms behind them.
Finally, the crew would be alone. Even though they were at
80,000 feet and clipping along at three times the speed of sound,
there was little sensation of speed, says Elliott. At that altitude,
there were no visual clues as to their progress.
Outside, the temperature on certain portions of the SR-71's
titanium skin neared 1,000 degrees Fahrenheit. Expansion from
the heat made the plane grow nine inches longer during a normal
flight--an amazing statistic considering the Blackbird's titanium
skin. Once on the ground again, the plane would cool and contract
to its former size. Inside, air-conditioning kept the tight-fitting
cockpit at a cool sixty degrees.
Though the stars always were out at that altitude, there was
little time to gaze at the constellations. Most of a flight was
spent monitoring instruments and staying on course, recalls Elliott.
When traveling at thirty-two miles a minute, a wrong turn can
result in a detour of several hundred miles--or more--quickly.
Planned turns started 100 miles ahead of the actual event. It
was hard work. The plane's design may have been from the future,
but its controls were strictly from the 1950s and 1960s, before
cockpit computers took over many routine flying chores.
The All-Important "X"
SR-71 crews took off knowing their exact longitude and latitude,
their precise location on the face of the Earth. An "X"
on the ground under the front wheels of the plane's landing gear
marked the exact spot. The crews needed to know just where they
started to get where they were going. At an altitude of fifteen
miles, there weren't any landmarks.
"This [aircraft] flew very conventionally, very responsive[ly],"
Elliott says. "The systems were very reliable. We very seldom
had any problems at all. But you could never relax. If you have
a problem up there. . . ." Elliott's voice trails off. (Others
did sometimes have mechanical problems, including number of SR-71
"unstarts," or engine shutdowns in flight.)
Most Blackbird flights ranged in duration from two and a half
to six hours. Some, however, might last as long as ten or twelve
hours. One day, the destination may have been the Persian Gulf
or Cuba, the next China or Lebanon, all places the planes are
known to have operated over in an estimated sixty-five million
miles of flying and spying.
On the ground afterward, support crews were warned not to touch
the Blackbird for half an hour, until it cooled down. The post-flight
inspection checklist included 650 steps.
"It was one of a kind," Elliott says, a little sadly,
lightly tapping an old photo of himself in a flight suit, helmet
under the crook of his right arm, standing in front of an SR-71.
His hair and the plane are black.
