The Type HGU-2A/P protective flying helmet was standard issue for U.S. Air Force flight crews during the early 1960s. First issued in 1961, the HGU-2A/P was an improved version of the HGU-2/P by the addition of ventilation holes, extra padding, and the H-154/AIC headset.

This particular helmet was worn by the donor, Capt. Ben Allen while flying F-105s from Takhli Royal Air Force Base in Thailand in 1965. During his tour of duty, Capt Allen flew 81 combat missions over North Vietnam.
