Question: When was the roller coaster that surpassed Wicked as the tallest roller coaster at Lagoon Amusement Park built?
Context: The Cyclone was a wooden roller coaster that operated at Revere Beach in Revere, Massachusetts, from 1925 until 1969.  When Cyclone was constructed, it was the tallest roller coaster ever built, as well as being the first roller coaster in the world to reach 100 ft in height.  In addition to being the tallest roller coaster of its day, some also claim that it was the largest and fastest roller coaster in the world, with a length of 3600 ft and top speeds between 45 and 50 mph (some dispute the speed record claim and instead award that honor to the Giant Dipper).
