Design Montgolfier

Design Montgolfier is an upgrade in Cossacks 3, available at the Academy.

Background
In 1782, brothers Montgolfier have invented a paper balloon capable of rising into the sky when filled with warm air. Pilate de Rosier performed the first flight on a fabric balloon in 1783. A balloon creates a carrying power thanks to warm air in it being lighter than the surrounding atmosphere. Such balloons are called Montgolfiers after their inventors. According to a manuscript found in Riazan (Russia), a cleric Kriakutnoy has performed a flight on a balloon filled with warm air before brothers Montgolfier, in 1731. However, his flight was unsuccessful. Napoleon has used balloons for reconnaissance - to observe enemy positions. Also balloons were used in various festivities and parades. Giving a demonstration of scientific achievements, they helped raising people's morale.

Effect

 * Reveals the whole map

Trivia

 * The reason why the balloon is so expensive for Scotland and Ukraine is for balance, as these two countries can be used in late game, yet don't have the Progress to the 18th Century upgrade.
 * Algeria and Turkey are lacking the upgrade, as it would be counter-intuitive and useless to these rush nations.
