Galactica is a flying roller coaster located in the Forbidden Valley area of Alton Towers amusement park in Staffordshire, England.

Guests ride in a prone position, meant to produce the feeling of flight, as the train passes close to the ground, under footpaths, and narrowly past trees and rocks.

Alton Towers conceived the concept of a flying roller coaster in 1990, twelve years before Air eventually opened.

[2] Later that year, Alton Towers initially advertised the new rollercoaster as a "next generation Aerial Inversion Ride"; subsequently revealing the name Air.

This proposed adding a new photo opportunity into the queue, enclosing the station building with new walls, and constructing additional theming elements around the ride area.

[11] In October 2015, the first promotional material was posted on the Alton Towers website, advising guests to "prepare for a new flight" and to "watch this space".

[12] On 12 January 2016, Alton Towers announced that Air would be re-themed as Galactica for the 2016 season and would include on-ride virtual reality (VR) headsets simulating a ride through the cosmos.

[22] After exiting from this lie-to-fly element, the train passes underneath a small ravine before pitching up into a tight turn over the plaza area.

[22] A 360-degree inline twist[7] is followed by a series of smaller turns and dips in the track, before coming to a stop on the brake run and returning to one of the ride's two stations.

In Amusement Today's annual Golden Ticket Awards, Air was ranked in the top 50 among steel roller coasters numerous times following its opening.
