Most tech advances came from Britain, America just copied and asked China to cheaply produce them.
Uh maybe the factory shit, but I'm pretty sure we invented the Plane, the Helicopter, Wu-Tang Clan, and AIDS (Our government made it to destroy Africa so we could ravage it's mineral wealth).
Sit and spin.
the plane:
The first recorded attempts at aviation were made by Yuan Huangtou and Abbas Ibn Firnas. Leonardo da Vinci drew an aircraft in the 15th century. Francois Pilatre de Rozier and Francois d'Arlandes flew in an aircraft lighter than air, a balloon. The biggest challenge became to create other craft, capable of controlled flight.
Sir George Cayley, 6th Baronet (December 27, 1773 – December 15, 1857) "Father of Aerodynamics" was a prolific English engineer from Brompton-by-Sawdon, near Scarborough in Yorkshire. He was a pioneer of aeronautical engineering
the helicopter:
In 1906, two French brothers, Jacques and Louis Breguet, began experimenting with airfoils for helicopters and in 1907, those experiments resulted in the Gyroplane No.1. Although there is some discrepancy about the dates, sometime between 14 August and 29 September 1907, the Gyroplane No. 1 lifted its pilot up into the air about two feet (0.6 meters) for a minute. However, the Gyroplane No. 1 proved to be extremely unsteady and required a man at each corner of the airframe to hold it steady. For this reason, the flights of the Gyroplane No. 1 are considered to be the first manned flight of a helicopter, but not a free or untethered flight.
That same year, fellow French inventor Paul Cornu designed and built a helicopter that used two 20-foot (6-meter) counter-rotating rotors driven by a 24-hp (18-kW) Antoinette engine. On November 13, 1907, it lifted its inventor to 1 foot (0.3 meters) and remained aloft for 20 seconds. Although this flight was smaller in its achievement than that of the Breguet brothers, it was greater in accomplishment in that it was the first true free flight with a pilot. The Cornu helicopter would achieve a height of nearly 2 meters but also proved to be unstable and was abandoned after only a few flights.
aids:
AIDS was first reported June 5, 1981, when the U.S. Centers for Disease Control and Prevention recorded a cluster of Pneumocystis carinii pneumonia (now still classified as PCP but known to be caused by Pneumocystis jirovecii) in five homosexual men in Los Angeles.
Three of the earliest known instances of HIV infection are:
A plasma sample taken in 1959 from an adult male living in Kinshasa, today part of the Democratic Republic of the Congo.
HIV found in tissue samples from "Robert R.", a 15 year old African-American teenager who died in St. Louis in 1969.
HIV found in tissue samples from Arvid Noe, a Norwegian sailor who died around 1976
