HALO jumps are used to enter hostile territory undetected when threats to both Airmen and aircraft are expected.
Insanely Cool New Hover Vehicle
A resurrected hover vehicle won't fly through dense forests as effortlessly as the "Star Wars" speeder bikes from "Return of the Jedi," but its intuitive controls could someday allow anyone to fly it without pilot training. The aerial vehicle resembles a science fiction flying bike with two ducted rotors instead of wheels, but originates from a design abandoned in the 1960s because of stability and rollover problems. Aerofex, a California-based firm, fixed the stability issue by creating a mechanical system — controlled by two control bars at knee-level — that allows the vehicle to respond to a human pilot's leaning movements and natural sense of balance. "Think of it as lowering the threshold of flight, down to the domain of ATV's (all-terrain vehicles)," said Mark De Roche, an aerospace engineer and founder of Aerofex. Such intuitive controls could allow physicians to fly future versions of the vehicle to visit rural patients in places without roads, or enable border patrol officers to go about their duties without pilot training. All of it happens mechanically without the need for electronics, let alone complicated artificial intelligence or flight software.
