John Oliver: Falling in Love with America

It was like falling in love with a girl who was just throwing up all over herself -- softly holding her hair back and whispering to her that everything was going to be alright. To me, thats what the last eight years were like, here in America: projectile vomiting all over yourself as the rest of the world rubbed your back, saying, Sssshhh, thats it. Let it all out.

First international ballon race

In 1906, the world's first international balloon race began. It was won by a coal-gas balloon, the United States. Pilot Lt. Frank P. Lahm of the U.S. Signal Corps and his co-pilot Maj. Henry B. Hersey, of the Weather Bureau, flew 402 miles (647-km) from Paris, France, to Scarborough, England, in 22-hr 15-min, to win the Gordon-Bennett Cup. The race sponsor, James Gordon-Bennett (1841-1918), publisher of the New York Herald, was known for financing Henry Stanley's expedition into Africa to find David Livingstone. The 1906 balloon race launched at the Jardin des Tuleries, with 250,000 spectators. Of 17 entrants, only seven reached England safely. The American win promoted ballooning back home, and nominated the U.S. as host for the next race, in 1907, held at St. Louis, Missouri.«[Image shows the 1907 race launch of the United States with Major Hersey as pilot, replacing Lahm who had health problems.]
