JW001, also known as the Jurassic One, was a Eurocopter EC130 B4 helicopter that was used at Jurassic World.
Visitors who bought the "Adrenaline Package" of Jurassic World would be a passenger of the JW001 and would be given a tour of Isla Nublar. It appeared to be the personal helicopter of Simon Masrani. Before the incident at Jurassic World, Masrani flew himself, his flight instructor and Claire Dearing, albeit somewhat clumsily, to the Indominus rex Paddock, which caused the unfortunate instructor to suffer from air sickness.
During the rampage of the escaped Indominus rex during the Isla Nublar Incident of 2015, JW001, piloted by Masrani Global Corporation CEO Simon Masrani, was outfitted with an M134 Minigun as means of trying to kill the hybrid. JW001 followed the I. rex to the Jurassic World Aviary, where it was attacked by escaped Pteranodons, that were flying out of a hole in the aviary. The Pteranodons killed the gunner and co-pilot and hit the helicopter from multiple angles. Unable to take anymore, and despite Masrani's efforts to stabilize the copter, JW001 spiraled out of control, and smashed into one of the walls of the enclosure before exploding when it hit the ground, killing Masrani.
To make matters worse, the hole created by the helicopter's destruction released the Aviary's inhabitants, who proceeded to attack the park visitors - resulting in yet another addition to the growing conflict. 
JW001 appears in the game, but is not pilotable and is unidentified as it lacks its designation on its tail.
In the opening cutscene for the level "Under Attack" Simon uses the helicopter to stop the escaped Indominus rex like in the film. However, instead of being attacked by Pteranodons they are instead attacked by Dimorphodons and all passengers survive.
In the Jurassic World hub, its remains can be found inside the Jurassic World Aviary with Masrani stuck under what is left of the helicopter trying to escape. He can be freed by pulling a hover switch for Pteranodon, which unlocks a gold brick and makes him purchasable.
JW001 is a vehicle in Jurassic World: Evolution.
