Once in the aircraft, the hose was plugged into a port in the aircraft. It had an 18-inch hose sprouting from the waistband. The G-suit, worn over our flight suit, looked like a cross between cowboy chaps, and tight-fitting jeans with holes cut in the knees and the seat. Powered by a G-Suitįor one thing, a “G-suit” was added to our gear. Basic flight included all of the maneuvers that we had learned in the T-37, but the responsiveness of the T-38 and the physical sensations were entirely different. Our training program called for approximately 90 hours in the T-38, including initial aircraft training, two-and-four-ship formation flying, instrument flying, supersonic flight, night flying, and low-level high-speed navigation. It is a tandem two-seat, twin-jet, advanced “fast-jet” (supersonic) trainer with a top speed of 1.3 Mach (speed of sound) and maximum G-load of plus 9.0, i.e., the airframe could withstand load forces equal to nine times the force of gravity. The T-38, or “White Rocket,” was an entirely new flying experience. The T-38: A White Rocket The T-38 Talon is a two-seat fast-jet trainer capable of supersonic flight. With six months to graduation, we transitioned to the T-38. I survived-actually passed-the first two phases. It's important to understand that velocity alone plays no role in the symptoms of injuries of a human.In 1970, Air Force flight training was divided into three phases, primary flight in the Cessna T-41 (Cessna 172), primary jet in the Cessna T-37, and advanced jet in the Northrop T-38 Talon. This accident was intense enough to pull the pulmonary artery from her heart. The devastating car crash of Princess Diana of Wales in 1997 was estimated to range somewhere between 70–100 g's. If a force of 4 to 6 g's is held for more than a few seconds, the results could be devastating such as blackouts to death. Pilots on the other hand are trained to undergo accelerations of 9 g's to pull quick maneuvers during flight for less than a second. They undergo forces of maximum up to 3 to 4 g's for brief periods of time. Roller coasters give humans a thrill ride. Pilots, roller coaster rides, and car crashes are sufficient examples of g-force. Its reason is that each different body part has a higher density than another which causes certain organs to undergo more g-force than other organs. When placing a human under high acceleration the brain, lungs, ribs (any bones), and women's breast (tissue fat) all affect the death of the human. I'd like to discuss some of the factors which play a key role in which may cause the death of human due to high acceleration.įirst of all, the human body is composed of different organs each organ containing its own different given density. Everything is said to feel normal at 1 g, twice as heavy at 2 g, and weightless at 0 g. The common term "g-force" is a measure of acceleration and is not a measure of force. But what is dangerous is the high acceleration or deceleration given at a certain time interval. In general, high velocity doesn't produce harmful injuries. Some popular examples of acceleration could be a falling apple (accelerating), a car stopping (decelerating), or direction of motion changing. Velocity has both magnitude and direction. That's because velocity is a vector quantity, one which acceleration depends upon. The changing direction, increasing speed, decreasing speed of an object are all factors of acceleration. Acceleration is known as the rate of change of velocity with time. The change of velocity of any object is said to be accelerating. The average value is about 65 g's, so I used thatįor the fatal impact acceleration on a human being." These figures assume the human is taking the impact on the chest/stomach, theīack, sides or the head. Severe injury or death is 75 g's for a "50th percentile male", 65 g's for a "50th percentile female", and 50 g's for a "50th percentile child".
