Give significance in final one-sentence paragraph. List inclosures at lower left. Begin tert of report on AF Form 1#—Part IL) 1. The Swedish Defense Staff has no proof that any unidentified flying objects, missiles or vehicles have passed over or near Sweden to date. 2, All reports of sightings in Sweden during the past year, irrespective of to whom they were submitted, have been funneled to a special section of the Defense Staff, where the sightings were plotted, In each case ar exhaustive interrozation of the sighter followed, somewhat along the lines of the ZI for Project "SIGN", All 4) evidence obtained of sirhtinss was explicable in terms of astronomical phenomena, Ze In addition, 3 ercund reader stations and 2 radar equipped destroyers coopere- ated in maintaining watch. The radar equipments wers Swedish modified British sets of fairly short range and were not operated on a 2k hour basis; however, no unexplained Sightings were made with this equipment. wis l. Conclusion; Although the possibility exists that objects have traversed Sweden and its adjacent waters, no proof has been obtained to confirm such flight in any instance. COMMENT: The cooperation of the Lefense Staff in securing this information was undoubdt- edly given in an effort to emphasise their need for additional U.S. radar equipment. The Swedish Air Board had previously negotaited with the Bendis Corporation for 20 TPS- la sets but had beer refused an export license by our State Department. The members of the Defense Staff, to whom I talked, were eager to point out the good use to which such equipment could be put for both ourselves and the Swedes as instanced by our mutual interest in unidentifiable flying objects. However, I am convinoed that our refusal to grant an export license for such equipment will do more good in implementing our nation- al policy, as expressed in the National Security Council documents NSC 26/1, than would the information we might receive from the use of such equipment here. /3/ Donald L.
