Most standard shaped tethered balloons are readily identified when near the ground or when the tether is visible. Other experimental tethered balloons are not so easily identified. During the 1960s, Balloon Branch personnel flew experimentally shaped tethered balloons from deep canyons of central New Mexico. To a distant observer, from a vantage point above the canyon rim, where the tether and ground anchors are not visible, an experimental tethered balloon might lead some persons to speculate as to the oddly shaped balloon’s origin and purpose. One design of a low altitude tethered balloon may have inspired at least one account of an “alien” craft. In _The Truth About the UFO Crash at Roswell_, the authors published a drawing of a crashed alien spaceship allegedly based on a drawing given to them by an anonymous witness.[96] When this drawing is compared to a photograph of an experimental tethered balloon flown at Holloman AFB in March 1965, the similarities are undeniable.[97] The tethered balloon and the NASA space probes are just two examples of the uncommon technologies that were flown in New Mexico by the Holloman Balloon Branch.

This experimental balloon, is strikingly similar to the “alien” craft. (_U.S. Air Force photo_)] Today, the Air Force maintains a reduced but still highly capable high altitude balloon program at Holloman AFB. The Space and Missile Command, Test and Evaluation Unit (SMC/TE, OL-AC) represents the sole Department of Defense high altitude research balloon capability. The ability of a U.S. Air Force high altitude balloon to lift a scientific payload to more than 100,000 feet, above 99 per cent of the earth’s atmosphere, for days at a time, presents a profoundly useful scientific tool at a fraction of the cost of a space research platform. Recent tests that utilized Holloman balloons included atmospheric sampling and gravity measurement experiments, high altitude astronomic studies, weapons systems evaluations, and gamma ray detection experiments. While most tests continue to be launched from the permanent balloon launch facility at Holloman AFB, U.S. Air Force balloon crews have recently launched balloons from numerous field locations in the U.S. (including two sites in Roswell), as well as Alaska, Panama, and Antarctica.
