Unknown Pulp Magazine Cover

This document is not a pulp magazine issue but rather official U.S. Air Force UFO investigation records from Project 10073 (Blue Book), dated November 1957. The records consist of two sighting report cards from Harrisburg, Pennsylvania. The first describes a white streak of light appearing in the western sky at dusk, observed for six or seven minutes by ground witnesses and obscured by buildings and trees. The second reports a basketball-sized egg-shaped object, initially white, that emitted red sparks upon disappearing and appeared to be revolving with protruding points. The conclusion notes that Venus's position matched the exact location and time of this sighting. Both cases document witness observations and investigative assessments regarding potential explanations including balloons, aircraft, and astronomical phenomena.
