The course of the object was otherwise without variation in altitude or direction, proceeding at an estimated 40,000 feet toward the southwest.

b. Object was sighted by Captain METCALF at 0730 hours EDT, 1 July 1952, and was observed by him for ten (10) minutes.

c. Sighting was by visual observation through smoked glasses, with no optical or electronic aids.

d. Observer sighted object while standing in the vicinity of Hangar "B" at Laurence G. Hanscom Field, Bedford, Massachusetts.

e. Identifying information on observer: Captain ROBERT E. METCALF, AO 563825, Petroleum Officer, 6520th Supply Squadron, 6520th Test Support Wing, Laurence G. Hanscom Field, Bedford, Massachusetts, is 33 years of age, and has served six years of active duty and five years of reserve duty with the USAF. Captain METCALF is not rated, but appeared thoroughly familiar with all types of aircraft and advised that he has never seen a comparable object.

f. Weather conditions: METCALF advised that at the time of the sighting the sky was perfectly clear, and a slight northeast wind was blowing. Weather conditions at 0730 hours EDT 1 July 1952 were reported by the U. S. Weather Department, Logan International Airport, Boston, Massachusetts, for the Boston area as follows: "Thin scattered clouds at 26,000 feet, northwest wind at 6 miles per hour, visibility 12 miles, temperature 60 degrees."

g. No activity or condition is known that might account for the sightings. However, METCALF stated that his attention was first drawn to the object while he watched the vapor trails of what appeared to be two (2) jet aircraft proceeding in a southeast direction. The object described intersected the jet vapor trails and continued to the southwest.

h. No physical evidence exists, and no interception action was taken. METCALF advised however, that he proceeded to the base operations tower after having observed the object for a few minutes, and that attempts to locate the object with a pair of #750 Navy-type binoculars from that vantage point resulted negatively.

i. Manner of disappearance: METCALF advised that he again saw the object while on the way to the tower, but that its distance had increased considerably, and that from the tower it was no longer visible, with or without binoculars.

METCALF further advised that upon sighting the object he called it to the attention of M Sgt JAMES STINER, AF 15120/40, and M Sgt JOSEPH R. BOSH, AF 11031/57, both of 6520th Air Police Squadron, Hanscom Field. On
