Q: During the American Civil War, the Union was the first to field a submarine. 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.

Q: In 1991 the FA decided that only one replay should be played (starting with the 1991--92 competition). If this game ended in a draw, extra time would be played, followed by penalty kicks if the match was still even. In 1999 it was decided that the semi-finals should be decided in one game, with extra time and penalties used to determine the outcome if the game ended in a draw. Replays are still used in earlier rounds, however, though were eliminated in the quarter-finals in 2016. The last FA Cup Semi-final replay, in 1999, saw Manchester United take on Arsenal at Villa Park. This turned out to become one of the most memorable semi-finals of all time, with Peter Schmeichel saving a last-minute penalty from Dennis Bergkamp and a Ryan Giggs extra time goal deciding the outcome in Manchester United's favour. In 2003 this goal was voted the greatest ever in FA Cup history.
