The French-designed Alligator was the first U.S. Navy sub and the first to feature compressed air (for air supply) and an air filtration system. It was the first submarine to carry a diver lock, which allowed a diver to plant electrically detonated mines on enemy ships. Initially hand-powered by oars, it was converted after 6 months to a screw propeller powered by a hand crank. With a crew of 20, it was larger than Confederate submarines. Alligator was 47 feet (14 m) long and about 4 feet (1.2 m) in diameter. It was lost in a storm off Cape Hatteras on April 1, 1863, while uncrewed and under tow to its first combat deployment at Charleston.

The role of the supraspinatus is to resist downward motion. The supraspinatus resists downward motion while the shoulder is relaxed as well as when carrying weight. Such a tear usually occurs at its point of insertion onto the humeral head at the greater tubercle. Even though the supraspinatus is the most commonly injured muscle of the four muscles in the rotator cuff, the other three muscles that comprise the rotator cuff, the infraspinatus, teres minor, and subscapularis, may also be injured.
 Question: is the supraspinatus tendon part of the rotator cuff Context: Even though Lana eventually marries Lex in season six, Al Gough argues that Lana still loved Clark and Clark still loved her. The only reason Lana was with Lex was because Clark forced her in that direction and she ended up getting in over her head. By contrast, writer Caroline Dries feels that Lana did love Lex, and that she did not make any hasty decisions when she agreed to marry him. Dries believes that the progression of the show demonstrates that Lex earned Lana's love. To answer viewers that hated to see Lana marry Lex, Dries contends that as viewers we are seeing all of Lex, including how evil he truly is, while Lana only sees the portion of Lex that appears good.
