This was confirmed in other scientific journals shortly after the Cloud appeared. For example: | |||
:'''Abstract''' - Measurement of the filamentary noctilucent cloud of 2 November 1963 yields a height of 56 km. Study of the motion and orientation of the cloud confirms the hypothesis that these unusual clouds appearing in the southwestern states are produced by the launching of rocket vehicles from the Pacific Missile Range.<ref>Science 3 January 1964: Vol. 143 no. 3601 pp. 38-39 DOI:0.1126/science.143.3601.38, Low-Latitude Noctilucent Cloud of 2 November 1963, Aden B.

Dr. MacDonald made no mention of the noctilucent cloud phenomena in his report. | Questions have also been raised as to why was the cloud not seen prior to appearing over Flagstaff.
