In May 1952 a Civil Aeronautics Administration Aviation Safety Agent from Seattle wrote to Project Blue Book about a sighting during World War II:

         In 1943 I was an Instrument Flying Instructor assigned to the 6th Ferrying Group of the Air Transport Command and based at Long Beach, California. My daily routine consisted of flying four, one hour instructional periods in the morning with a different student for each hour. On one flight while proceeding on the southwest leg of the Long Beach radio range at 5000 feet altitude at the normal cruising airspeed of a BT-13A type trainer, my student and I witnessed an object at this point which to this date defies logical explanation.

         This object appeared from the northeast on a level flight path and turned while decelerating from a great speed to fly parallel to us for approximately 30 seconds before it disappeared from view at a slight climbing attitude (5 degrees) bearing to the right across out ship's nose and at speed which I can now estimate to be between 2000 to 5000 miles per hour.

         So many years have since passed that it is difficult to reconstruct the appearance of the object but a few prominent facts are still clear and vivid in my mind. They are:

    1)   This incident occurred above a fog overcast with clear and unlimited sky condition above.

    2)   The object was an International Orange in color, had an elliptical or rounded forward structure, was proportioned in a manner as a conventional aircraft's fuselage.

    3)   The rear of the object either had no significance or I am unable to remember its profile.

    4)   No propellers or jet orifice were visible; nor was any flame, smoke or vapor trailed.

    5)   It decelerated in an unstable manner. (IE) Wobbling outward from its banked attitude while turning and dipping longtitudinally up to ten degrees from its flight path.

    6)   It flew exactly abeam at our altitude and while in this position exhibited no other motion than the identical forward speed of our ship.

    7)   Its departure from the area also appeared unstable at the start of its acceleration. It seemed to lurch forward with the rearward portion wobbling until its direction was established.

    8)   From its position abeam to ten degrees to the right of our nose and five degrees high until out of sight took approximately one and one half second.

          A series of unusual events contributed to the fact that this object made no striking impression on my student and me. There had been a rumor at this time that Lockheed Aircraft Company were building a jet aircraft and we thought we had witnessed the flight of it. I learned much later that the first flight of the Lockheed P-80 did not take place until over a year from this period of time.

         Furthermore, I had a camera in the aircraft at this time and although it was hanging on the 'oil dilution' control nob and ready to use, I did not use it for fear of photographing a highly secret aircraft.

         I can (remember) telling the student through the intercom: "Come out from under the hood. Lockheed's jet is flying formation with us."

         The student pushed back the hood and both of us witnessed the object flying alongside and its flight out of sight. Then the student went back under the hood and the episode was ended. In retrospect, I believe the fact that neither of us at that time attached anything unusual about it must imply that it resembled something which would have encompassed known aerodynamic outlines. Until I first witnessed an early flight of the P-80, I was under this impression. Immediately upon seeing the relative slowness of the P-80 and its easily identifiable outlines, I realized we had witnessed some inexplicable object...."
