History
In the 20th century, contrary to the United States, Europe did not have a single sky — i.e., one in which air navigation is managed at the European level. Furthermore, European airspace is among the busiest in the world with over 33,000 flights on busy days and airport density in Europe is very high. This makes air traffic control even more complex. The EU Single European Sky initiative was instigated to overcome this fragmentation and capacity limitation by structuring airspace and air navigation services at a pan-European level. To prepare for future capacity, etc., the SESAR programme was initiated in 2004 (as a continuation of the Eurocontrol project SESAME). In June 2010, European and American authorities reached a preliminary agreement on interoperability between their future air traffic management systems, SESAR and NextGen.

Famous quotes containing the word history:
“We may pretend that we’re basically moral people who make mistakes, but the whole of history proves otherwise.”
—Terry Hands (b. 1941)
“Whenever we read the obscene stories, the voluptuous debaucheries, the cruel and torturous executions, the unrelenting vindictiveness, with which more than half the Bible is filled, it would be more consistent that we called it the word of a demon than the Word of God. It is a history of wickedness that has served to corrupt and brutalize mankind.”
—Thomas Paine (1737–1809)
“He wrote in prison, not a History of the World, like Raleigh, but an American book which I think will live longer than that. I do not know of such words, uttered under such circumstances, and so copiously withal, in Roman or English or any history.”
—Henry David Thoreau (1817–1862)
