Human-powered Helicopter Fails to Lift Off
Peter writes "The Human-powered helicopter didn't even get off the ground. A team of University of British Columbia engineering students tried to win the $20,000 US prize offered by the American Helicopter Society. Three metres off the ground and hover for a minute was the challenge. But before the rotors were able to produce enough buoyant force they hit each other. More details: Vancouver Sun."
As far as I know, The USA is the only country with the word "America" in it.
Hence the term "American."
Are you really that daft?
Also note that Mexico is formally called the "United Mexican States" by the Mexican government (actually: Estados Unidos Mexicanos).
