 transatlantic flight is the flight of an aircraft across the atlantic ocean, from europe or africa to north america or south america, or west-to-east. such flights have been made by fixed-wing aircraft, airships, balloons and other devices. early aircraft engines did not have the reliability needed for the crossing, nor the power to lift the required fuel. there are difficulties navigating over featureless expanses of water for thousands of miles, and the weather, especially in the north atlantic ocean, is unpredictable. since the middle of the 20th century, however, transatlantic flight has been routine, for commercial, military, diplomatic, and other purposes. experimental flights (in balloons, small aircraft, etc.) still present challenges for transatlantic fliers.  ==history== the idea of transatlantic flight came about with the advent of the balloon. the balloons of the period were inflated with coal gas, a moderate lifting medium compared to hydrogen or helium, but with enough lift to use the winds that would later be known as the jet stream. in 1859, john wise built an enormous aerostat named the atlantic, intending to cross the atlantic. the flight lasted less than a day, crash-landing in henderson, new york. thaddeus s. c. lowe prepared a massive balloon of  called the city of new york to take off from philadelphia in 1860, but was interrupted by the onset of the american civil war in 1861. (the first successful transatlantic flight in a balloon was the double eagle ii from presque isle, maine, to miserey, near paris in 1978.) ===first transatlantic flights===  the possibility of transatlantic flight by aircraft emerged after the first world war, which had seen tremendous advances in aerial capabilities. in april 1913 the london newspaper the daily mail offered a prize of Â£10,000nevin, david.
