SAN FRANCISCO - The night of July 30, 2013, was a night like any in the San
Francisco Bay Area – foggy, with a high probability of low cloud
ceilings. Those who know the area are well aware of the
micro-climates and chilly fog layers that can overtake the Bay in a
matter of minutes. Images of the city skyline and the twin stantions
of the Golden Gate Bridge peering out through snow-like clouds are a
common sight.
Coast Guard Air Station San Francisco, based at
San Francisco International Airport, is home to four Coast Guard
MH-65D Short Range Recovery Helicopters. Lt. Cmdr. James Kenshalo
was the duty aircraft commander that evening, along with co-pilot
Lt. Beau Belanger. Both were well aware of the unpredictable weather
conditions, and had practiced the “low visibility route” many times;
a precision passage which forces the pilot to fly beneath both the
Bay and the Golden Gate Bridges in order to safely reach offshore
airspace.
And then their night duty
suddenly changed ... when the quiet was interrupted by the SAR alarm.
Both pilots and the assigned air crew — Aviation Machinery
Technician Petty Officer 3rd Class Travis Swain, and Aviation
Survival Technician Petty Officer 3rd Class Corey Fix — were geared
up and ready to perform. The crew of CG-6515 was directed to launch
and rescue six hikers requiring immediate evacuation from a secluded
cove in the vicinity of Point Reyes, Calif., notably one of the
foggiest places in the country. As the rescue crew lifted off, they
quickly encountered a dense fog offering less than 200 feet of space
between the waterline and the cloud layer, and a mere one-half
nautical mile of visibility.

“It was intense,” said Kenshalo.
“You get a feel for fog here in San Francisco. This fog was pushing
us down.”
The barrier of mountains ahead blocked the most
direct route to the search area. Exercising “superior crew resource
management,” the decision was made to utilize the low-visibility
route offshore and follow the coastline to the hikers' location. But
precipitous cliffs, poor visibility and low cloud ceilings made the
search conditions extremely hazardous. As they navigated past
steep-walled bluffs along the coastline, the crew used night vision
goggles and the aircraft's radar, at last locating the stranded
hikers in a narrow cove surrounded by towering rock fingers.
The easy part
was over. With only a few feet of clearance between the rotor blades
and the jagged face of the cliffs, Kenshalo and Belanger struggled
agianst buffeting winds to maintain position over the survivors.
“I couldn't go up because of the fog, I couldn't go sideways
because of the cliffs, I couldn't go down because of the water,”
said Kenshalo. “So I hovered, trying to stay close to the beach
without hitting the cliffs.”
As the helicopter hovered over
the small beach, flight mechanic AMT3 Swain lowered rescue swimmer
AST3 Fix down to the cove in order to triage and assess the
frightened hikers and prepare them for hoisting. The deafening roar
of the engines echoed off the bluffs, rendering traditional radio
communications all but useless.
“We were all on the same
page, but couldn't hear each other,” said Fix. “The radio was pretty
much out, so I switched to hand signals. That worked out well.”
Using nighttime hand signals and solid crew coordination, the pair
worked to hoist four of the survivors aboard. But by now, the
helicopter was running dangerously low on fuel and had to turn back.
Swain then lowered emergency provisions to Fix, who would remain
behind with the two hikers.
Managing their dwindling fuel
reserves, Kenshalo and Belanger reversed their perilous course to
the station, delivering the first four stranded hikers to emergency
medical technicians waiting at the air station. They landed with
less than 20 minutes of fuel remaining in their tank.
The
rapidly deteriorating weather made the second low-visibilty route
back to the incident even more challenging. Not only were the pilot
and co-pilot unable to see suspension cables, towers, or the auto
decks of bridges but the added moisture in the air caused the
helicopter's landing lights to create visual illusions, disorienting
the crew. Forced to shut off the lights, they made the transit
blind, using only the radar to guide them.
“And now it's
really dark,” Belanger reiterated. “There was so much humidity in
the air that our normal search lights weren't working. I couldn't
even see the cliffs.”
Instead they used flares to reflect
light off the cliffs and illuminate the cove. Once again operating
the helicopter at the edge of its performance envelope, the crew
completed another hoist, raising the first of the two remaining
stranded hikers to safety. As each flare was extinguished, the pilot
was forced to initiate a demanding “no-reference orbit” in the fog
surrounding the confined inlet until another flare could be lit.
“We had some flares [aboard] that would light up for about 18
minutes, so we dropped one in the ocean and it lit up the cliffs
just fine,” said Belanger. Using the light, the crew repositioned
themselves for the final hoists.
Suddenly the wind shifted,
significantly increasing the amount of engine power required to
maintain a hover and causing the aircraft to unexpectedly settle
towards the water. The crew was forced to momentarily abort the
hoist as Fix, now dangling beneath the helicopter, used his own body
to shield the remaining hiker from banging against the rocks.
“I braced for impact,” chuckled Fix as he later related the
incident. “Maybe it was the adrenaline, but I'm still not sure how
that one didn't hurt!”
Knowing
that if the helicopter experienced a second similar power loss, it
would likely cost them their lives, Kenshalo maneuvered the
helicopter “nose-to” the cliff without the usual emergency “fly-out”
route in order to optimize the buffeting wind ricocheting off the
rock face around the helicopter. This unconventional and risky
maneuver provided just enough power to complete the final hoist.
The moment Fix and the remaining hiker were safe in the cabin,
Kenshalo completed a hovering pedal turn and put the aircraft on a
safe heading before completing an instrument-only climb through the
dense fog. At 2,000 feet, the helicopter finally broke free of the
clouds with the last of the rescued hikers.
Emotionally and
physically exhausted after three hours of the most challenging
flying conditions in nighttime fog, including four demanding hoists
and six low-level passes beneath two bridges, the crew landed –
again, with only minutes of fuel remaining.
For pilots of all
professions, every geographic location comes with its own unique set
of challenges. “I've been on a couple of really tough cases, but
this one was the hardest to pull off,” said Kenshalo.
“At the
end of the night, you come back and slump down in a chair, and the
wind knocks right out of you.”
