Rickyswmm, Lightning Loops were manufactured by Arrow Dynamics. Schwarzkopf's shuttles did not have the staircase or drop before the loop, and were completely different mechanically. Visit my site to see the difference between them.
Only one of the Lightning Loops, the "lower" loop, remains in operation as Diamond Back at Frontier City. The upper loop remains in storage at Six Flags America after several years there as Python.
