Palm Springs is a desert resort city in Riverside County, California, situated within the Colorado Desert's Coachella Valley. Covering approximately 94 square miles, it is the largest city in Riverside County by land area, and more than 10% of its land is part of the Agua Caliente Band of Cahuilla Indians reservation — the administrative capital of the most populated reservation in California. Today it is internationally known as a destination for mid-century modern architecture, golf, and dramatic desert scenery framed by the San Jacinto Mountains. For Season 13 of Expedition Unknown, Gates came not for the spa resorts but for the open desert sky — flying aboard a vintage 1945 C-47 Skytrain to understand what may have doomed a plane carrying 18 members of the Women's Army Corps that disappeared off the coast of West Africa that same year. The flight segment used Palm Springs as a backdrop for a hands-on investigation into the aeronautical mysteries surrounding one of World War II's least-known American tragedies.

The Douglas C-47 Skytrain — nicknamed 'The Gooney Bird' — was one of the most essential Allied transport aircraft of World War II. As Gates explains on camera, nearly 10,000 were built during the war, and the type served in virtually every theater of operations, from the Pacific to North Africa to the skies over Normandy on D-Day. General Eisenhower himself reportedly singled it out as one of the most valuable assets of the Allied campaign. With a wingspan of nearly 100 feet, the C-47 could carry 28 fully equipped paratroopers or up to 10,000 pounds of cargo, powered by two Pratt and Whitney air-cooled engines producing a combined 2,400 horsepower.
Despite its storied record, the C-47 had known mechanical quirks. Pilots Nightengale and Rose, speaking with Gates during the Palm Springs flight, pointed to two specific vulnerabilities relevant to the 1945 WAC crash: the propeller feathering control, which could become stuck and prevent pilots from reducing drag on a failed engine, and the possibility of landing gear remaining in the down position — a condition that would have significantly compromised the aircraft's ability to stay aloft. These are recognized mechanical failure modes in the historical record, though their precise role in the WAC crash has never been definitively established.
The broader context of wartime aviation also factors into expert assessments. Training pipelines during World War II were compressed by necessity, and pilots were frequently flying aircraft with limited hours of experience in specific emergency procedures. As Gates observed during the segment, the pilot on the doomed WAC flight had fewer than 50 hours at the controls — a fact that mainstream aviation historians would recognize as a contributing risk factor, though not an automatic death sentence for a flight.
Gates' Palm Springs segment did not claim to solve the mystery of what brought down the WAC transport — nor did it purport to. Instead, it laid out the competing mechanical hypotheses in a grounded, evidence-based way before the investigation moved on to the actual crash site region off West Africa. That honest framing — presenting possibilities rather than conclusions — is consistent with how aviation accident investigators approach cases where physical evidence is incomplete or still on the ocean floor.
Palm Springs covers approximately 94 square miles, making it the largest city in Riverside County by land area — despite being best known as a compact resort destination.
More than 10% of the city of Palm Springs sits on land belonging to the Agua Caliente Band of Cahuilla Indians, which administers the most populated reservation in California from this location.
The C-47 Gates flew during filming rolled off the production line in March 1945 — just two months before the crash of the WAC transport he was investigating, making it an almost exact contemporary of the doomed aircraft.
General Eisenhower reportedly singled out the C-47 Skytrain as one of the most valuable Allied assets of World War II — high praise for what began as a modified commercial airliner.
Palm Springs is a fully accessible, well-serviced destination with a regional airport (Palm Springs International Airport) offering direct flights from many U.S. cities. The desert landscape Gates used as a backdrop for the C-47 flight is generally visible from the surrounding valley, though the specific airfield used in filming is not a public tourist attraction. Visitors come primarily for the city's architecture tours, aerial tram, and desert scenery.
Palm Springs is itself the primary city; Los Angeles is approximately 100 miles to the west.
Late fall through early spring (October through April) offers the most comfortable temperatures, with highs typically in the 70s and 80s°F; summer months can see extreme heat well above 100°F. Spring wildflower season, when conditions allow, draws additional visitors to the surrounding desert.
Normandy Beaches, France
The C-47 Skytrain Gates flew over Palm Springs served at Normandy on D-Day — a direct historical connection Gates specifically mentions in his on-camera narration during the flight segment.
Lake Superior
Lake Superior has been the subject of Gates investigations into aircraft and shipwreck disappearances, reflecting a thematic overlap with the WAC crash mystery explored in the Palm Springs flight segment.
