Tracing Friendship Across Borders: Chinese Aviation Trainee Correspondence and the Intimacies of Diplomacy, 1946–57

In 1943, twenty-one aviators from the Chinese National Air Force were sent to San Diego to train at the Consolidated-Vultee Aircraft Corporation, forming the largest cohort of Chinese trainees at any U.S. aircraft plant during World War II. While officially serving the aims of Sino-American military collaboration, these young men forged deep personal relationships with Grover and Pauline Trask, a local Anglo-American couple running a cafeteria near the base. While the training ended in 1946, the trainees and the Trasks maintained a warm and decades-long correspondence and material exchange when they stationed around the world in the postwar era, exchanging letters, photographs, and gifts.

This paper examines the trainees’ letters as informal extensions of Nationalist diplomacy beyond official state channels. While the aviators were trained to serve the Republic of China militarily, their interpersonal relationships abroad —rooted in everyday acts of care and memory— functioned as informal diplomatic acts aligned with the Nationalist regime’s efforts to maintain transnational influence and cultural visibility. These everyday exchanges, I argue, played a crucial role in shaping postwar diplomatic imagination and diasporic identity beyond frameworks of Cold War diplomacy or geopolitical strategy. Using digital humanities methods—including topic modeling, Named Entity Recognition, network analysis, and mapping—this study analyzes the letters as a record of affective transnationalism and grassroots diplomacy. Rather than situating these trainees solely within geopolitical frameworks, it repositions them as transcultural intermediaries whose friendships and exchanges reveal how diplomacy was also forged through material exchange, through letters, and across friendships.
