As they began their spiral descent, centrifugal force caused them to swing outward before returning to the station. This is commonly acknowledged as the first suspended roller coaster type ride. This tall steel tower figures prominently in early postcards of Long Beach Pier  (Pine Ave., later to join the west side of Rainbow Pier.) Often confused – Many photos and postcards seen on the web are mis-captioned Bisby's Spiral Airship. If the structure has one long thin approach of steel to the top of a cylinder and camel-back return, that's Bisby's Spiral Airship. If the structure pictured is a thick wooden cone spiral slide, the entrance next-door east of Lee's Barbeque with a switchback stairway to a shack on top, the caption should read "Niagara Barrel". The Pike's first more traditional wooden roller coaster opened for business in June 1907. It was built by Fred Ingersoll and named the Figure 8 after the shape of the tracks. It was built on pilings that reached out over the water. According to a 1966 editorial in the "High Tide", the newspaper of Redondo Union High School, a rider met tragedy when he disobeyed a sign instructing riders not to stand up: "He apparently thought this would spoil his fun, so he proceeded to stand up. Unfortunately, his head was knocked off." Figure 8 was closed in 1914 and demolished to clear the way for new development. In 1914, the Pike Amusement Zone undertook several upgrades and a new roller coaster named the Jack Rabbit Racer was opened in May 1915, becoming the second largest racing coaster in the country. It was again designed by Fred Ingersoll, this time with the help of John Miller. It was part of the Silver Spray Pier which included several new rides and concessions. One could look down through the tracks and see the water. In the mid twenties, several expansions were made to the area and the Jack Rabbit Racer was remodeled, raising the ride's dips to a greater height and steepness. An elevated band shell was built into the coaster with track running right over it. Jack Rabbit Racer was removed in 1930. One of the best-known historic coasters, the Cyclone Racer was built in 1930 to replace the Jack Rabbit Racer. The Cyclone Racer was a dual-track (two trains could launch side by side at the same time), racing wooden roller coaster, the brain child of Fred Church and built by Harry Traver. To increase thrill, the new coaster was built on pilings over the ocean, several hundred feet beyond the shore.
