Dear Neil Armstrong: Letters To The First Man From All Mankind, James R. Hansen Oct 2019

Dear Neil Armstrong: Letters To The First Man From All Mankind, James R. Hansen

Purdue University Press Book Previews

In the years between the historic first moon landing by Apollo 11 on July 20, 1969, and his death at age 82 on August 25, 2012, Neil Armstrong received hundreds of thousands of cards and letters from all over the world, congratulating him, praising him, requesting pictures and autographs, and asking him what must have seemed to him to be limitless—and occasionally intrusive—questions. Of course, all the famous astronauts received fan mail, but the sheer volume Armstrong had to deal with for more than four decades after his moon landing was staggering.

Today, the preponderance of those letters—some 75,000 of …

NPP eBooks

Unmanned Aircraft Systems are an integral part of the US national critical infrastructure. The authors have endeavored to bring a breadth and quality of information to the reader that is unparalleled in the unclassified sphere. This textbook will fully immerse and engage the reader / student in the cyber-security considerations of this rapidly emerging technology that we know as unmanned aircraft systems (UAS). The first edition topics covered National Airspace (NAS) policy issues, information security (INFOSEC), UAS vulnerabilities in key systems (Sense and Avoid / SCADA), navigation and collision avoidance systems, stealth design, intelligence, surveillance and reconnaissance (ISR) platforms; …
