An Escape Pod is a type of small one manned craft developed by the Visitors. They are stationed aboard a Mothership and can be summoned by a special command sequence whereupon they float to the ground before a pilot. The cockpit moves to the aside allowing a passenger to board and a virtual holographic interface is used to give the commands to the escape pod which is able to depart a Mothership and move to planetside.
The former Queen Diana placed a number of secret escape pods aboard her Mothership in case she ever needed to depart in an emergency. She, however, never had a chance to use them after being overthrown by her own daughter, Anna. Many years later, she revealed the existence of the pods to her grand daughter Lisa and Ryan Nichols thus allowing the latter to escape from the Mothership. After seeing through a surveillance camera of his Hybrid daughter Amy, Nichols activated the command sequence that brought the secret escape pod which allowed him to escape Anna's security forces and arrive on the surface of Earth in order to enlist the aid of the Fifth Column.
