PB PENETRATION At approximately 290200 EST Oct 75, AFOC relayed a report from Loring AFB, ME indicating that one unidentified helicopter, possibly two helicopters, had penetrated Loring AFB from Canadian territory with one helicopter landing briefly in proximity to a weapons storage area. Attempts to locate or identify the intruding helicopters by an Army National Guard helicopter were unsuccessful. Sightings of the unidentified helicopter(s) were limited to security guards. A similar incident with a single helicopter occurred during the early morning of 28 Oct 75. Permission has been granted by Canadian authorities to give pursuit into Canadian airspace if subsequent contact is effected by U.S. helicopters.
