"In the meantime the Air Force continues to look into a curious fact I have uncovered: the insignia seen by patrolman Zamora looks very much like the logo of AstroPower, a subsidiary of the Douglas Aircraft Corporation. I found the logo in an ad they recently published in an engineering journal. I am suspicious of this aspect of the sighting. To my knowledge there has never been a genuine report of a saucer with an insignia painted on the side. Could the Socorro object be a military prototype?" (p.110-111, Chicago, 27 September, 1964)
"It bore an insignia which closely resembled the logo of Astropower, a company founded about 1961 as a subsidiary of Douglas, under the presidency of the propulsion expert Y. C. Lee." (p. 286)
"I thought of AstroPower and the McDonnell Douglas company, who is rumored to have a secret team, employing a physicist named Stanton Friedman to collect physical data in a hush-hush manner." (p.304, Chicago, 2 August, 1967)
