The Gremlin Special and the hidden valley rescue that used a glider snatch off a jungle floor

On May 13, 1945, a Douglas C-47 nicknamed the Gremlin Special crashed into a mountainside in New Guinea’s uncharted Baliem Valley, killing 21 of the 24 people on board. The three survivors — stranded in a valley whose indigenous Dani inhabitants had never seen the outside world — were eventually rescued over 47 days using a glider snatch technique that yanked a Waco CG-4A from a standstill to 90 miles per hour in roughly three seconds.

What Was the Gremlin Special?

The Gremlin Special was a Douglas C-47 operating out of a base near Hollandia, Dutch New Guinea. By May 1945, the war in Europe had ended and the Pacific war was winding down. The Army Air Forces had begun allowing morale flights over New Guinea’s interior, where mountains rose to 15,000 feet above cloud forests and unmapped valleys.

On that day, 24 passengers — military personnel and several Women’s Army Corps (WAC) members — boarded for a recreational sightseeing flight over the Baliem Valley. Local aircrews had nicknamed it “Shangri-La” because it resembled a lost paradise from the air: a bright green valley floor with terraced gardens and thousands of people living in near-total isolation from the modern world.

The pilot threaded the C-47 into a narrow canyon. Weather closed in — fog, rain, vanishing ridgelines — and the aircraft struck the side of a ridge and broke apart.

Who Survived the Crash?

Only three of the 24 people aboard survived the crash and the fire that followed:

Corporal Margaret Hastings, a WAC from upstate New York, with severe burns on her legs and a deep gash on her forehead
Lieutenant John McCollom, also burned, who discovered his twin brother’s body in the wreckage
Sergeant Kenneth Decker, with what turned out to be a broken back

They had no radio, no signaling equipment, and no way out. The valley floor sat at roughly 5,000 feet, walled in by ridges exceeding 12,000 feet. The nearest Allied base was over 100 miles away through some of the most rugged terrain on Earth.

How Did Rescuers Reach the Survivors?

Search aircraft located the wreckage from the air, but the valley had no airstrip, no road, and no trail. The Army determined the only way in was by parachute.

Captain C. Earl Walter Jr., a Filipino-American paramedic, led a team that jumped into the valley — dropping into an uncharted landscape, hoping the clearing spotted from altitude was flat enough to land on, and hoping the indigenous population would not be hostile.

Walter’s team found the survivors and began a days-long trek down to the valley floor. Hastings could barely walk. Decker’s back was in terrible shape. But they reached the valley, where the Dani tribespeople proved remarkably welcoming. The Dani brought sweet potatoes, showed curiosity rather than hostility, and coexisted with the growing American camp as more paratroopers jumped in and the Army established a supply drop zone.

Why Couldn’t They Just Fly an Airplane In?

The valley floor was uneven, covered with Dani gardens and drainage ditches. Building a conventional runway would have taken weeks the rescuers did not have, and the terrain would not have cooperated regardless.

Helicopters were not a viable option. In 1945, the Sikorsky R-4 existed but lacked the range and altitude performance to operate in a mountain valley in New Guinea.

That left one option: the glider snatch.

What Is a Glider Snatch and How Did It Work?

The Waco CG-4A was a combat glider — a large, boxy aircraft built from steel tube and fabric, capable of carrying 13 troops or a jeep. It had seen action at Normandy, Operation Market Garden, and the Rhine crossings. And there was a technique developed earlier in the war for recovering a glider without a runway for a tow plane to land on.

The procedure worked like this:

Two poles, roughly 12 feet high, were set up on the ground with a loop of braided nylon rope strung between them.
The glider’s tow line was attached to that loop.
A C-47 equipped with a special hook mechanism flew in at 15 to 20 feet off the ground, snagged the loop, and the stretching rope absorbed the shock as the glider accelerated from a dead stop to flight speed.
The occupants went from stationary to approximately 90 miles per hour in about three seconds.

The technique had been practiced extensively elsewhere. It had never been attempted in a mountain valley surrounded by ridges with unpredictable winds funneling through the gaps.

The Snatch Off the Valley Floor

The rescue team cleared a strip in the valley and set up the poles. Survivors and rescue personnel loaded into the glider. A C-47 came in low along the valley floor and snatched the glider off the ground.

Hastings later described the moment of the snatch as the most violent physical sensation she had ever experienced — sitting still one second, yanked forward and upward the next, valley walls spinning past the windows, the airframe groaning under the strain.

The tow held. The glider climbed out behind the C-47, cleared the ridgeline, and flew back to Hollandia. Multiple glider snatches were required to evacuate everyone, each one as harrowing as the first.

What Happened to the Survivors?

The entire episode lasted 47 days from crash to final evacuation.

Margaret Hastings recovered from her injuries and lived until 2004, reaching the age of 86.
John McCollom carried the loss of his twin brother for the rest of his life.
Kenneth Decker recovered from his broken back.
The Dani people of the Baliem Valley eventually had sustained contact with the outside world. The valley is accessible today, though still remote.

The story is told in extraordinary detail in Mitchell Zuckoff’s book Lost in Shangri-La, the primary source for much of this account.

Why the Gremlin Special Rescue Still Matters

The Baliem Valley rescue represents aviation problem-solving at its most desperate and inventive. With no runway, no helicopter capability, and mountains on every side, the solution was to hook a rope to a glider and yank it into the sky behind a transport plane. It worked because the people involved understood what an airplane could actually do when pushed to its limits.

And at the center of it was Margaret Hastings — a woman in 1945 with burns on her legs, trekking through jungle in New Guinea, living among a tribe that had never seen the modern world, then climbing into a fabric-and-steel glider to be snatched off the ground by a C-47.

Key Takeaways

The Gremlin Special crashed on May 13, 1945, killing 21 of 24 passengers during a recreational sightseeing flight over New Guinea’s Baliem Valley.
Three survivors — Hastings, McCollom, and Decker — endured 47 days in a valley inhabited by the Dani, an indigenous people with no prior contact with the outside world.
Paratroopers jumped into the valley to reach the survivors, since no aircraft could land in the terrain.
The glider snatch technique, using a low-flying C-47 to hook and accelerate a Waco CG-4A from a standstill, was the only viable extraction method — and had never been attempted in such extreme mountain terrain.
Mitchell Zuckoff’s Lost in Shangri-La remains the definitive account of the rescue.
