3 July 1952, STINER and BOSH were separately interviewed by Special Agent JULIUS B. POPPINGA. Time, location, method of sighting, weather conditions, direction of flight, and disappearance were identical to that reported by METCALF. Several differences will be noted, however, relative to the description of the object.

j. STINER described the object as resembling a small blimp, having a blunt front, cigar-shaped, and similar to an "airplane without wings or tail assembly." STINER noticed no exhaust or noise, and no changes of altitude or course. Length of the object was estimated as two to three hundred feet, and no tail features, wings, or aerodynamic features of any kind were observed. STINER estimated the altitude of the object to be about 20,000 feet. He described its forward motion to be irregular, first barely moving, and then proceeding at "about the speed of a C-47."

k. BOSH advised that he could not estimate the size of the object, but described it as oval-shaped, and believed that it was trailed by two distinct vapor trails, similar to that associated with conventional aircraft at very great altitudes. BOSH noticed no variation in the speed, altitude, or line of flight, and estimated the speed to be about 130 miles per hour and the altitude to be "over 30,000 feet." BOSH noticed no noise, and stated that he could distinguish no wing or tail surfaces. He added that while both STINER and METCALF used sun glasses while observing the objects, he did not, and that his vision was impaired by the brightness of the sky and the sun.

l. Identifying information on STINER and BOSH: M Sgt STINER is 50 years of age, and has served 19 years with the ground forces and 4 years with the Air Force. He has never been on an air crew, and claims no special knowledge pertaining to aircraft, but advised that he has never observed an airplane in flight, at any angle, resembling the object described, and was aware of no known object which might account for it. M Sgt BOSH is 32 years of age, and has served 11 years with the Air Force, primarily in inspection and investigation work. BOSH advised he has done considerable reading in relation to unconventional aircraft, but could not account for the object described in any way.

m. This sighting appears to be a verification and one of the same as sighting observed by ERWIN W. NELSON between 0731 and 0734 hours EDT on 1 July 1952 and reported in 1st District OSI file 24-0-256 on 3 July 1952.
