The Mint of Poland, in an effort to bring man’s dreams of
conquering the skies and admiring the world from up above closer,
decided to produce a new series of silver - commemorative coins,
entitled “How Man Conquered the Skies” to present
the numerous attempts over the years to soar through the air.
The first coin of the
series depicted Icarus, the mythological forerunner of aviation. The
second coin presented the invention of the Montgolfier brothers - the
hot air balloon whilethe third commemorated the Glider designed by Otto
The coins will be struck at a very low mintage - up to 6,000
pieces - using Ag 925 blanks, in proof quality.

The era of airplanes began from the breakthrough invention by the
Orville (1871-1948) and Wilbure (1867-1917) built a plane which was
capable - to fly thanks to its combustion engine. In 1903 they
successfully completed their first controlled flight, which lasted 12
Another important step pushing aviation to the next level was the
development of the jet engine in the 1930s. Piston engines proved to be
of little value when flying at high speeds and significant altitudes
where the air is rarefied.
As early as 1928 a British engineer, Frank Whittle (1907-1996),
patented his first design of jet engine. However, the first jet
airplane called Heinkel He 178, was constructed in Germany by Ernst
Heinkel in 1939. During World War II British and American troops
deployed their jet airplanes in numerous important and deciding
The jet aircraft of today are capable of breaking the sonic barrier.
