Hammond has a deeper emotional understanding of creating attractions for children and families, and wants to make Jurassic Park a scientific reality. He notes that his first attraction was a motorized flea circus, but for the park he wants to show visitors something real rather than an illusion. However, he is misguided in his steadfast belief that his creations are under control, as he underestimates the power of genetics and nature. He also has little regard for pure scientific research, being more interested in the applications of genetic engineering. When the security system breaks down, he and his staff work to restore power and rescue the experts and his grandchildren, while themselves remaining in a secure control room. Eventually, however, he and the other survivors ruefully leave the island, with a depressed Hammond agreeing with Grant that the park has failed and must never be endorsed.
