Project 10073 Record Card — Helena, Montana, 21 July 1961

On 21 July 1961, at approximately 0030Z, a B-52 crew commanded by Colonel R.H. Worrell, Jr. of the 4141st Strategic Wing (SAC) observed two unidentified objects while flying at 38,000 feet near Helena, Montana. The objects were described as round, white, and starlike in appearance, with a brightness estimated at three to four times that of the Echo satellite. The crew observed the objects for seven minutes using both the naked eye and a periscopic sextant. The objects maintained a steady, straight, and level flight path, moving from East to West at an estimated speed of 440 knots. The initial sighting occurred at four degrees elevation below the moon, and the objects eventually disappeared into the sun. Weather conditions were reported as clear with unlimited visibility. The crew attempted to gain more detail through the sextant, but no additional features were revealed. The report was submitted under the provisions of AFR 200-2. Initial intelligence analysis by the 4141st Strategic Wing considered the possibility that the objects were a satellite or the second stage of a rocket. However, the movement from East to West was noted as unusual, and subsequent evaluation ruled out satellite possibilities. The final assessment concluded that because the sighting characteristics and flight patterns were consistent with an aircraft, but the movement was atypical, and given the high qualifications of the observers, the case remained classified as unidentified. The report notes that aircraft features can be distorted at great distances, especially at dusk when viewing toward the sun, but the observers should have been able to identify standard aircraft features if present.
