Introduction to the "Hump" Mission
The episode delves into one of World War II's most perilous and lesser-known aviation missions: flying over the Himalayas, famously known as "The Hump." Caroline Alexander discusses her new book, Skies of Thunder, which sheds light on the extraordinary challenges faced by young, often undertrained pilots tasked with navigating this treacherous air route.
Contextualizing the Burma Road and Geopolitical Stakes [02:35 – 06:05]
Ellen Evans sets the stage by asking Alexander about the Burma Road's significance.
Caroline Alexander explains that the Burma Road was initially a strategic effort initiated by Chiang Kai-shek in 1935 to combat communist forces in China. However, the road's importance escalated when Japanese forces occupied Burma in 1942, effectively blockading China. President Roosevelt's pledge to supply China necessitated the creation of an "aerial Burma Road," leading to the audacious mission of flying supplies over the Himalayas.
"We're talking today about a remarkable aviation mission during World War II in an arena of the war that's not so often covered." [02:35]
Feasibility and Challenges of the Aerial Burma Road [06:05 – 14:03]
Ellen Evans inquires about the mission's feasibility.
Alexander outlines the daunting 800-mile flight from Assam, India, to Kunming, China, through some of the world's most difficult terrain. Despite initial assessments deeming it feasible, the mission faced severe weather challenges due to the convergence of massive air systems—warm, moist air from the South China Sea and dry, icy blasts from the Tibetan plateau and Siberia. Additionally, the lack of advanced navigation systems made the journey even more hazardous.
"These pilots were essentially flying blind for most of the journey until they come into Kunming." [10:20]
Pilot Demographics and Training Deficiencies [10:20 – 14:26]
Contrary to expectations, many pilots assigned to The Hump were inexperienced. With a shortage of seasoned aviators—most experienced pilots were engaged in combat missions—young and relatively untrained men were thrust into this critical role. Efforts to bolster pilot expertise included sending commercial airline pilots for intensive training, but many pilots had minimal flight hours.
Alexander highlights the psychological toll and stigma faced by these "hump pilots," who were often relegated to the lower echelons of the Air Transport Command and self-referentially dubbed themselves the "Forgotten Bastards of India."
"These were very young, inexperienced pilots... they were part of the Air Transport Command, the acronym for which was ATC." [14:03]
Technical Limitations of Aircraft [14:26 – 19:48]
The primary aircraft used was the DC-3, affectionately known as the Dakota in Britain. While stable and forgiving, the DC-3 had limited carrying capacity and was plagued by mechanical issues, including fuel and hydraulic leaks. Subsequent iterations, like the C-46, introduced larger cargo capacities but were susceptible to catastrophic failures due to ice accumulation on the wings.
"The DC3 was an astonishingly stable aircraft. It felt like the pilot's friend." [14:26]
Life in the Jungle and Survival Challenges [19:48 – 30:53]
Alexander paints a vivid picture of the grim living conditions for the pilots on the ground. Housing was rudimentary, with bamboo thatched huts vulnerable to monsoon rains, insects, and diseases like malaria and dysentery. The jungle's oppressive environment further exacerbated the pilots' stress, compounded by the psychological burden of believing their efforts were futile as supplies were often lost to the black market or fell into Japanese hands.
"Pilots were equipped with these little jungle survival kits... which often had been plundered in China." [19:48]
The Severide Incident: A Story of Humanity and Survival [30:53 – 36:34]
One of the most compelling narratives discussed is the Severide incident, where Erich Severide, an American correspondent, survived a crash over The Hump. Despite the plane's failure, 20 out of 21 passengers survived the bailout. The survivors faced immediate danger in the jungle, but their rescue was facilitated by the indigenous Naga people, showcasing remarkable humanity and cultural cooperation.
"There were extraordinary stories of one person who went to look for a downed plane... People brought him things." [30:53]
Psychological Impact: Humpitis [36:34 – 44:38]
Alexander introduces "Humpitis," a unique psychiatric disorder emerging from the extreme stress of flying The Hump. Symptoms included severe morale collapse, anxiety, and trauma, leading some pilots to refuse future missions or suffer debilitating mental health issues. The stigma surrounding Humpitis was significant, often resulting in pilots being reassigned or court-martialed.
"Humpitis... is a collapse of morale, sometimes extreme to the point that people broke down and just refused to fly." [36:34]
Lessons Learned and Historical Significance [44:38 – 41:03]
In concluding the episode, Alexander emphasizes the importance of recognizing this hazardous mission's historical significance. She underscores the necessity of aligning ideology with intelligence, cautioning against allowing wishful thinking to override critical assessments. The enduring legacy of The Hump mission is reflected in the respectful relationships between American pilots and their Chinese counterparts, even decades later.
"Ideology and wishful thinking must never override intelligence... it is one's duty to pay attention to that intelligence and act accordingly." [44:38]
Conclusion
Caroline Alexander's exploration of The Hump mission in Skies of Thunder offers a poignant glimpse into the bravery, challenges, and psychological toll experienced by the pilots who dared to traverse one of the most dangerous air routes in history. The episode not only highlights a forgotten chapter of World War II but also serves as a testament to human resilience and the complexities of wartime logistics.
