As originally built, Aloha Stadium had various configurations for different sport venues and other purposes. Four movable 7,000-seat sections, each could move using air casters into a diamond configuration for baseball (also used for soccer), an oval for football, or a triangle for concerts. In January 2007, the stadium was permanently locked into its football configuration due to cost and maintenance issues. An engineer from Rolair Systems, the NASA spin-off company that engineered the system, claims that the problem was caused by a concrete contractor that ignored specifications for the concrete pads under the stadium.
