Blowgun, a weapon used by certain primitive tribes. It is essentially a straight tube, usually about eight feet (2.4 m) long, made from bamboo or hollowed-out wood, and fitted with a mouthpiece. Its missile is a dart, eight to ten inches (20 to 25 cm) long, with a tip coated with poison. The dart is blown out of the tube, but generally there is not enough force in the propulsion to kill without the poison. The weapon is used mainly for hunting, usually birds and monkeys; its use in war is infrequent. Blowguns are most commonly found among tribes in the jungles of Borneo, the Philippines, Malaysia, and South America.
The Nieuport 17 incorporated the best features of monoplanes and biplanes in what was termed the sesquiplane setup. It featured a large top wing and a smaller lower wing joined by a V-shaped strut. Learn the advantages of this classic hybrid design.
Amphibious Warfare, military campaigns of combined land and sea forces. Since no military action of any size would be undertaken without also using air power, the word triphibious, meaning use of land, sea, and air forces, has been suggested, but it is not commonly used.
