      1. On Thursday, 17 December 1953., while flying near HHssleholm, SWeden, Captain
 Ulf Christiernsson sighted an 11 unknown" object. The follorring is the translation of
 a newspaper account of the incident:

                      "The chief pilot of Transair, Capt. Ulf Christiernsson, and his crew
                 chief, Olle Johansson, had a strange meeting over HHssleholm at 1437 hours
                 Thursday. A shining metal spherical elliptical object came toward them
                 traveling in the opposite direction from their machine at an estimated speed
                 of sound and approximately 600 meters below their DC-3, which was on its way
                 from Bulltofta to Bromma. It was visible six to seven seconds; Capt. Chris­
                 tiernsson, who had good silhouette recognition, stated that what he saw was
                 something absolutely new, possibly an unmanned robot.
                            11
                       The Transair plane was automatic controls when the meeting occurred.
                 Capt. Christiernsson did not have time for any measures other than to report
                 to Bulltofta and the Defense Staff, which later sent out the following com­
                 munique :

                      " •'rhe air crew of a civil aircraft observed on Thursday at 1437 hours
                 over the area of HRssleholm an unknown object moving in the opposite direction
                 from the airplane. The object was observed for six to seven seconds. At that
                 time and altitude the weather was clear. Because of the low lying cloud for­
                 mations the object is not thought to have been seen from the ground. The De­
                 fense Staff does not know o.f any Swedish plane that was in that area at the
                 time in question. An investigation is being conducted.•

                      "Previously I have been extremely skeptical about all the stories of
                 mysterious objects -- called flying saucers -- that have been seen at diverse
                 points, said the Captain. Now I don't know exactly what to think; but it did
                 seem to me that we had seen a robot of some kind. When I first caught sight
                 of the object, which like us was in the civil air corridor, I thought it was a
                 jet. We had, however, received no word that any such thing was on the way.
                      "The object came toward us at what I would say was the speed of sound;
                 we were flying at an altitude of approximately 2,150 meters and the object was
                 around 600 meters below us. It was going in a southwesterly direction and
                 disappeared after six or seven seconds.

                      •tThe object had a strong metal shine; the crew chief, Johansson, who coulc
                 see it longer than I, thought it was almost phosphorescent. The flying weathel
                 was excellent above the clouds, which were at an altitude of about 1500 meters,
                 and the sun was shining brightly. The object was proceeding just above the
                 clouds.

                      "The first silhouette I got diagonally from the right was narrow. When
                 it was nearly directly under us, however, I saw that it was nearly round, just
                 slightly elliptical.

                      "The object, which could definitely not have been a meteor, gave off no
                 waste gases or condensation traces.
                        11
                       Was I afraid? No, but curious, very curious, concluded Captain Chris­
                 tiernsson.
                        I
                      tChristiernsson has seen just about everything in aviation and has very
                 good silhouette recognition. From 1942 to 1946 he was a volunteer serving in

                making some thirty raids in a Mosquito against enemy territory, in both North
                Africa and Italy.
                     "Air Force Chief, General Nordenskiild, announced that it had been ascer­
                tained that the object could not have been any Swedish aircraft.
                     •• 'We are now investigating/' he continued, 'what our radar stations might
                have spotted.•"

      2. Captain Christiernsson is 41 years of age and was born in sl<Rne in the souther
 part of Sweden. An extremely reliable source in the Royal Swedish Air Board, who was
 born in the same town and who is a life-long acquaintance of Capt. Christiernsson's,
 has stated that Christiernsson is charming and well-liked, but that he is also most wi­
 trustworthy and was dismissed from a former position for "financial difficulty''• Dur­
 ing the last war, Christiernsson tried to take a Swedi.s h Air Force B-18 and fly to Eng­
 land, but was intercepted at Gothenburg and was put in jail. Although it is generally
 agreed in the Swedish Air Force that Captain Christiernsson is one of the best (and
 most discussed) pilots in Sweden today, he has never served with the RSAF except as a
 reserve captain.

      ;. Although the source above personally doubts Christiernsson•s story, the news­
 papers report that the Defense Staff is continuing its investigation of the incident.
 This office is attempting to obtain further information on the occurrence.
