What's the "een" in Halloween?
aircraft designed to launch torpedoes. In about 1910 the navies of several countries began to experiment with torpedo launching from low-flying aircraft, usually seaplanes. The first effective use of this technique occurred on Aug. 12, 1915, when a British Short Type 184 seaplane sank a Turkish vessel in the Dardanelles. Other navies' torpedo planes also had some success during World War I.
