This has proven entirely practicable and airships have thus weathered winds up to 60 miles per hour. Kite Balloon Development.--The kite balloon, which was invented by Major von Parseval and Captain Sigsfeld in 1803, was considerably developed during the war, first in France and then in Italy. The first improvement is due to Captain Caquot of the French Army, and consisted in substituting for the cylindrical envelope one of streamline shape, and in providing on the stern three inflated fins, which took the place of the sails and tail cups of the Parseval type. This arrangement insured much greater stability in high winds. With the same object in view, the Italian Air Service produced in 1918 a kite balloon of similar features but which differs from the Caquot in that it has a spherical envelope. This so-called AvorioPrassone balloon was extensively used on the Italian Front, where it rendered excellent service and proved easier to handle and capable of greater stability in high winds than the Caquot balloon.
