US Military FALLING BEHIND In Technology Documentary
An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines.
The human activity that surrounds aircraft is called aviation. Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others.
History
Main article: History of aviation
See also: Timeline of aviation
Flying model craft and stories of manned flight go back many centuries, however the first manned ascent – and safe descent – in modern times took place by hot-air balloon in the 18th century. Each of the two World Wars led to great technical advances. Consequently, the history of aircraft can be divided into five eras:
Pioneers of flight, from the earliest experiments to 1914.
First World War, 1914 to 1918.
Aviation between the World Wars, 1918 to 1939.
Second World War, 1939 to 1945.
Postwar era, also called the jet age, 1945 to the present day.
Methods of lift
Lighter than air – aerostats

Main article: Aerostat
Aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large gasbags or canopies, filled with a relatively low-density gas such as helium, hydrogen, or hot air, which is less dense than the surrounding air. When the weight of this is added to the weight of the aircraft structure, it adds up to the same weight as the air that the craft displaces.
Small hot-air balloons called sky lanterns date back to the 3rd century BC, and were only the second type of aircraft to fly, the first being kites.
A balloon was originally any aerostat, while the term airship was used for large, powered aircraft designs – usually fixed-wing. – though none had yet been built. The advent of powered balloons, called dirigible balloons, and later of rigid hulls allowing a great increase in size, began to change the way these words were used. Huge powered aerostats, characterized by a rigid outer framework and separate aerodynamic skin surrounding the gas bags, were produced, the Zeppelins being the largest and most famous. There were still no fixed-wing aircraft or non-rigid balloons large enough to be called airships, so “airship” came to be synonymous with these aircraft. Then several accidents, such as the Hindenburg disaster in 1937, led to the demise of these airships. Nowadays a “balloon” is an unpowered aerostat and an “airship” is a powered one.
A powered, steerable aerostat is called a dirigible. Sometimes this term is applied only to non-rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship (which may then be rigid or non-rigid). Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back. These soon became known as blimps. During the Second World War, this shape was widely adopted for tethered balloons; in windy weather, this both reduces the strain on the tether and stabilizes the balloon. The nickname blimp was adopted along with the shape. In modern times, any small dirigible or airship is called a blimp, though a blimp may be unpowered as well as powered.
I suppose people know what we spend on defense and technology every year….. so you actually believe this bullshit? That’s why we are who we are and the rest of the world can’t even dream of things we accomplish.
ok so your calling the most advanced fighter jet(raptor), an automatic laser missle defense system, a railgun, untrackable stealth jet, and missles that can be launched from a sattelite in space “falling behind”
dialogar e melhor que guerrear!
Yesterday dream, the USA F22 and F35.
Sounds like someone didn’t get a new cell.phone for their birthday

This is Retarded. USA MILITARY is more advanced then ever b4
well, everyone is forgeting naval and ground superiority.
American doesn’t need a weapon of mass destruction we are the weapon of mass destruction
Yaa that’s why the us can build fifth gen fighter’s while everyone else falls behind……F22/F35JSF
the US has always been behind everyone else on tech. they tend to steal tech from other countiries then when the other country builds a new system the yanks say they stole it from us. ok so why do the other countries systems cost half as much and work while the US systems fail lol. patriot anti air system proved not to work. they gave some to israel saying its the best system in the world and nothing will get past it. yet it has failed to spot any rockets being fired at israel let alone shot any down. F22 and F35 have been shown to be total failures. stealth planes get spotted as soon as they take off and tracked all the way to its target by old radar systems. prob is the yanks think just cause they cant track stealth planes no one else can. the yanks only have the abrahams cause they stole the plans of the challenger from the brits. most modern weapons syatems rely too much on tech. expensive to make and repair. fine for a short war against a small country. but try using them in a big war that lasts years against a country that can fight back. go back to WWII spitfire and hurricane. spitfire was expensive hard to make and hard to repair. hurricane cheap to make fast to make cheap and easy to repair and was better in a dogfight than a spitfire was. hurricane was made off wood with irish linnen skin. bit of glue and a wooden plug glue on a linnen patch over the hole and its back in the air in about 30 mins. spitfire metal frame metal skin. welding needed to patch up holes days to repair. F35 30 hrs to get it ready to fly for every 1 hr flying without having to do any repairs. recent tests showed the F35 cant even spot the russian planes let alone shoot them down. but the F35 can be seen by russian planes 500 miles away. the F22 and F35 will be blown to pieces before they even see who shot at them. the F18 F16 and F15 were the same. they tried all of them against russian fighters. every single 1 of them were shot down before they even saw the russian planes. that was short range dog fights not BVR. with BVR the russians have an even bigger advantage. even korea the yank fighters were getting blown to bits by the migs. the only advantage the yanks had in korea was more planes so they were able to put a lot more up to fight. but for every mig they shot down they lost 10. on the ground in korea the yanks got beaten easy. it was the french and british that held back the korean and chinese troops. while the yanks were running away the french retreated a bit. but the brits didnt budge an inch and repelled every attack. the war was a draw no side could win cause china had no weapons that could take out the centurion tank and the brits didnt have enough men and tanks to attack. maybe if the yanks didnt run away or hide behind the brits they might of been able to counter attack.
Actually, the kernel technology in computer was made by Chinese called Jeffrey Chuan Chu in 1946, he design the binary logic(soul of the computer), the arithmetic logic unit(core part of processor), bus for transferring data, miniaturization of computer(the pioneer of personal computer), but his famous contribution was hidden by the US for many decades.
LMAO, everyone in America know the weapon industry makes these propaganda videos so they can get billions more from Congress, hahahaha. good video title
falling?????? is a disaster as a country in all ways!!!
Having been there first gives an incredible advantage to the USA. There are counters to all of these weapon systems as we know the weaknesses of the stuff we developed a long time ago. We entangle our adversaries in a game of monkey see monkey do. We even let them steal what we want them to think they have. Perhaps the greatest weapon of all is knowing all their options and letting them think they know all of ours. The advantage is clearly in our corner. America’s greatest weakness is our sorry excuse for a public education system and our general ingnorent persuit of mindless pleasures. If our enemies take us down, it will not be for a lack of tech. We can be beaten by our internally strife. Our ever decreasing vision, endless infighting, and our selfish lack of vision as citizens, is the greatest threat to our survival.
bring me all those war planes and I’ll show you technology?it will be the end of the American enemies?i know exactly how to turn things around the right way??
