A New York University launch crew prepares a MOGUL balloon train for flight (Holloman AFB, NM, 1948). The three ML–307C/AP corner reflectors (left) are of the type that W.W. “Mac” Brazel recovered on a ranch near Corona, NM, in June 1947.
C.B. Moore, New York University Constant Level Balloon Project Engineer (left and standing), adjusts an AN/FMQ–1 radiosonde receiver/recorder. The absence of this equipment on the first NYU field trip in June 1947 (it was left behind in New York due to space limitations of the B-17 aircraft) prompted Moore to attach additional ML–307C/AP corner reflectors to MOGUL flights. The addition of the oddly constructed reflectors, intended to enhance radar returns, contributed to the confusion when Mogul Flight No. 4 returned to earth and was mistaken for a part of a flying saucer. Moore (right and reaching down) prepares experimental Project MOGUL microphones for launch (Holloman AFB, Alamogordo, NM, July 1948).
