Subject: DCI Knows What UFOs Are Not & IS Concerned

"At this time the reports of incidents convince us that there is something going on that must have immediate attention. The details of some of these incidents have been discussed by AD/SI (SI: Scientific Intelligence) with DDCI Sightings of unexplained objects at great altitudes and travelling at high speeds in the vicinity of major U.S. defense installations are of such nature that they are not attributable to natural phenomenon of known types of aerial vehicles."

Is there any need to develop on the importance of this memorandum?
