As I delved deeper into the annals of the Talleres Nacionales de Construcciones Aeronáuticas -TNCA- a peculiar sight kept catching my eye: A round, enigmatic structure gracing the grounds of the old Balbuena Airfield factory near Mexico City. Its presence was fleeting, appearing in photographs like a mysterious time traveler, only to vanquish from sight in the next frame.

This curious round facility stood sentinel before the TNCA’s administration building, a silent witness to the comings and goings of the airplane factory’s daily operations. Yet, its purpose, at least to an uninitiated like me, has remained a mystery.
At times, the space occupied by this rotund edifice played host to a solemn monument, adding another layer of intrigue to the ever-shifting landscape. Was the round building a temporary structure, its function tied to the rhythms of the factory’s needs? Or did it serve a more profound, esoteric purpose, known only to those who worked at the TNCA?
