Korea’s southern port city of Busan will host its massive annual fireworks display Saturday along Gwangalli Beach, illuminating the landmark Gwangan Bridge across the bay, city officials said Monday. The hourlong show starts at 7 p.m. Fireworks will be launched from three spots, Gwangalli Beach, Igidae Park and Dongbaek Island, to give the show more depth. The program will open with a 15-minute show by China’s Sunny Fireworks. It will be followed by a 30-minute show by Korea’s Hanwha Corp. on the theme “Busan’s dream,” featuring 25-inch shells, waterfall-style “Niagara” fireworks and multimedia lighting on the bridge. A five-minute “curtain call” display will then offer thanks citizens and festival staff. Before the fireworks show, the Black Eagles, the Korean Air Force’s aerobatic team, will put on an air show at 4 p.m., alongside beach events and busking by local indie bands. The city will offer some 17,000 paid seats. About 3,000 more seats than last year have been added, all set aside for foreign tourists and sold through overseas travel agencies and online trav
