According to the agency's 2003 strategic plan, "DARPA-supported researchers are studying how geckos climb walls and how an octopus hides to find new approaches to locomotion and highly adaptive camouflage. The idea is to let nature be a guide toward better engineering." Imagine the ink-squirting, suction-cup-covered frogman of the future!
Throughout much of 1921 and 1922, the project was shrouded in secrecy, but on December 18,1922, Dr. George de Bothezat's assistants rolled out the "Flying Octopus" for its first test at McCook Field, near Dayton, Ohio, observed closely by de Bothezat and curious onlookers in and on top of the experimental craft's hangar.
