Seal Team Commander Casey Ryback has retired from the Navy since the conclusion of the events in the first movie, and is now a chef at the Mile High Cafe in Denver, Colorado. Ryback is taking his niece Sarah Ryback on vacation, to reconnect and commiserate with her after the death of her parents. They board a train traveling westbound through the Rocky Mountains from Denver to LA. With the help of gun-for-hire Marcus Penn a couple dozen of his mercenaries, ex-CIA brain (and mentally unstable) Travis Dane commandeers the train, takes the passengers and crew hostage, and sets up a mobile control center. He hacks into the CIA database and gains control of a Top-Secret defence satellite he designed during his Agency days that has just been deployed. Funded by various foreign interests, he stands to make 1 billion dollars for using the space weapon to blow up the Eastern seaboard by targeting a nuclear reactor housed beneath the Pentagon. Dane taunts the Joint Chiefs in the Pentagon ... Written by Angus Brewer
Another approach is to build your communication around the concept of resources and HTTP methods. Instead of a remote procedure called addUser , you use a PUT request to /users/larry . Instead of encoding that user’s properties in function arguments, you define a JSON document format (or use an existing format) that represents a user. The body of the PUT request to create a new resource is then such a document. A resource is fetched by making a GET request to the resource’s URL (for example, /user/larry ), which again returns the document representing the resource.
In electrodynamic suspension (EDS), both the guideway and the train exert a magnetic field, and the train is levitated by the repulsive and attractive force between these magnetic fields.  In some configurations, the train can be levitated only by repulsive force. In the early stages of maglev development at the Miyazaki test track, a purely repulsive system was used instead of the later repulsive and attractive EDS system.  The magnetic field is produced either by superconducting magnets (as in JR–Maglev) or by an array of permanent magnets (as in Inductrack ). The repulsive and attractive force in the track is created by an induced magnetic field in wires or other conducting strips in the track. A major advantage of EDS maglev systems is that they are dynamically stable – changes in distance between the track and the magnets creates strong forces to return the system to its original position.  In addition, the attractive force varies in the opposite manner, providing the same adjustment effects. No active feedback control is needed.
