York, and the 1984 Louisiana World Exposition in New Orleans. Arrow Huss filed for bankruptcy in 1985, and 13 of the company's American officers negotiated a buyout. In 1986, the takeover was approved by the courts and the company re-emerged as Arrow Dynamics. Toomer served as president until 1993, Chairman of the Board until 1995, and as a consulting director until his retirement in 1998. In the late 1990s, Arrow Dynamic's bookings steadily decreased, with few installations toward the end of the decade. Despite attempts to keep up by implementing more updated design techniques, Arrow still found itself struggling to compete. Other manufacturers such as Bolliger & Mabillard and Intamin began to dominate the industry. Design and manufacturing costs for new, larger ride systems were increasing and competition grew. Bankruptcy loomed once again just as Arrow introduced X (subsequently known as X2) at Six Flags Magic Mountain, a 4th dimension roller coaster designed by Alan Schilke. X opened to massive media attention and received an initially positive reception; however, several mechanical problems caused the ride to be closed for repairs during much of its first year of operation. The company filed for bankruptcy again on December 3, 2001. At the end of October 2002, the remaining assets were sold to S&S Worldwide, a limited liability company related to amusement ride manufacturer, forming S&S Arrow. In November 2012, Sansei Yusoki Co., Ltd., of Osaka, Japan, acquired a 77.3% interest in S&S.
