Project 10073 Record Card and Related Correspondence — Cape Canaveral, August 1961

This document collection details an unidentified aerial phenomenon (UAP) reported on August 23, 1961, in the vicinity of Cape Canaveral, Florida, and Cuba. The sighting occurred shortly after the launch of an Atlas-Agena missile (Test #5050) at 10:04Z. Multiple witnesses, including a Sandia Corporation engineer and Marine sentries, reported observing a white, circular object that appeared to emerge from a gas cloud. The object was described as having the magnitude of Venus or Echo I, with a visible shock wave and a luminous trail that dissipated over several minutes. The object climbed steadily at an angle of approximately five degrees and moved eastward.

Official investigations by the Foreign Technology Division (FTD) of the U.S. Air Force were initiated to determine if the sighting was related to the missile launch or foreign reconnaissance. FTD reviewed optical tracking data (ROTI and IGOR films) and concluded that the object was not an artificial satellite. While some observers suggested the object might have been a booster separation, the FTD ultimately determined that the evidence was insufficient to definitively identify the phenomenon. The report explicitly states that the sighting was not a covert attempt to gather intelligence on AFMTC activities. The final assessment concluded that the event was likely due to natural phenomena, though the specific cause remained unidentified. The documentation includes record cards, internal Air Force messages, and technical information sheets, all of which emphasize the lack of physical evidence and the absence of radar confirmation for the object.
