Compared to later ones, planes in 1914 .............. .

At the outbreak of World War I, Germany
led the world In air power with 260
aeroplanes and 14 Zeppelins. Other allies of
Germany, including Italy, also had newly
formed air arms. The British had about 100
aircraft at this time; the French had 156.
Some 100,000 aircraft flew in the war,
primarily in support of ground and sea
troops. During the war, rapid advances were
made in both air power strategy and
technology. In 1914 the aeroplanes
mobilised for war were flimsy, kite-like
structures powered by engines of uncertain
power. At best, they could climb 3,000 feet
and fly at speeds of 70 miles per hour. At
worst, they could barely get off the ground.
Only four years later, single-seat aeroplane
fighters with 200-horsepower engines were
outfitted with machine guns to do battle at
15,000 feet in the air.
