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.
Since the 9/11 terrorist attacks, an estimated 54 other attacks on the U.S. have failed. And these are only the ones we know about. Some, like the underwear bomber and the shoe bomber, live on in infamy. Others are more obscure.
The Lockheed SR-71 Blackbird first flew in 1964, and since that time it has remained the world's fastest aircraft. Tanks in the inner wings and upper fuselage carry the 80,000 pounds of special, superheated fuel.
