The North American XB-21, also known by the manufacturer's model designation NA-21, and sometimes referred to by the name "Dragon", was a prototype bomber aircraft developed by North American Aviation in the late 1930s, for evaluation by the United States Army Air Corps. Evaluated against the Douglas B-18 Bolo, it was found to be considerably more expensive than the rival aircraft, and despite the ordering of a small number of evaluation aircraft, only the prototype was ever built.

“New York is a meeting place for every race in the world, but the Chinese, Armenians, Russians, and Germans remain foreigners. So does everyone except the blacks. There is no doubt but that the blacks exercise great influence in North America, and, no matter what anyone says, they are the most delicate, spiritual element in that world.”
—Federico García Lorca (1898–1936)
“... it was not very unusual at Washington for a lady to take the arm of a gentleman, who was neither her husband, her father, nor her brother. This remarkable relaxation of American decorum has been probably introduced by the foreign legations.”
—Frances Trollope (1780–1863)
