This document consists of a Project Blue Book record and associated correspondence regarding an unidentified aerial phenomenon reported in Philadelphia, Pennsylvania, on the night of October 10-11, 1966. The initial report was received via a telephone call from Lieutenant T.J. Spratt of the Willow Grove Naval Air Station at 2000 hours. The witness, whose name is redacted in the documents, reported observing a 'large pulsating ball of light' that appeared to be moving in a 'square block area' at approximately 2045 EDT. Following the report, Major Hector Quintanilla, Jr., Chief of Project Blue Book, sent a letter to the witness on October 13, 1966, stating that the information received was insufficient for a formal evaluation. The Air Force requested that the witness complete an FTD Form 164 to provide more comprehensive data. The case was ultimately filed under Project 10073 with the conclusion that there was insufficient data for evaluation.
