Northrop Grumman is a huge aerospace and defense technology company.
Helias Doundoulakis worked for over thirty-five years as a professional engineer at Grumman Aerospace Corporation and on many notable projects, including the MetLife Building in New York City, the Apollo Space Missions (such as the Lunar Excursion Module (LEM)), the F-14 Tomcat fighter jet, and the Space Shuttle. His crowning achievement is his patent for a radio telescope, used in the design for the largest of its kind at the NAIC Arecibo Observatory, in Arecibo, Puerto Rico (see U.S. Patent Office, Arecibo Observatory).
