III. CONCLUSIONS A. The unidentified aircraft reported by the T-33 pilots was probably a balloon launched by the Evans Signal Laboratory a few minutes before the T-33 arrived in the area B. The 1110 EDST radar sighting on 10 September 1951 was not necessarily a very high speed aircraft. Its speed was judged only by two operators' inability to use the aided tracking and this was possibly due to the operator being excited, and not the high speed of the aircraft. C. The 1515 EDST radar sighting on 10 September 1951 was a weather balloon. D. The 1050 EDST radar sighting on 11 September 1951 was a weather balloon. E. The 1330 EDST radar sighting on 11 September 1951 remains unknown but it was very possible that it was due to anomalous propagation and/or the student radar operators' thoughts that there was a great deal of activity of unusual objects in the area. |
