Costa Rica Napalm Bombing

The end of the original Jurassic Park novel is very different from the movie. In the movie, Ian Malcolm survives the T-Rex injuries, and gets on the Huey along with the rest of the survivors. In the novel, he dies due to excessive blood loss (at least it seems, he is revealed to have survived in The Lost World), and John Hammond is attacted (and killed) by Procompsognathids while trying to reach the coast of the island to get to the helicopter.

As Dr. Grant, Ellie Sattler, Tim and Lex reach the Costa Rican helicopter, they are met by Velociraptors, but the sound of the nearing helicopter scares them off. Once the remaining survivors board the helicopter, a Costa Rican military officer questions them about what happened on the island. After they finish their stories, the Coast Guard figures it too dangerous, and they fire 12.7 gallons of napalm all over Isla Nublar, destroying Jurassic Park and setting fire to the jungle, at which point Lex begins to cry. As they fly away from the island, a dying T-Rex roars in terrifying pain and agony, which makes Lex even more upset.

An allusion to this incident appears in the game Jurassic Park 2: The Chaos Continues. The player controls an InGen airplane that has to stop a military helicopter from bombing the island.

In reality, Costa Rica hasn't got a military Air Force or a permanent standing army.
