Hoverbout

Hoverbouts — also spelled as hovabouts and also known as transolar discs — were small circular flying platforms with a railing around the edge, used by Daleks for operation within a planetary atmosphere, in close planetary orbit and within close to medium range of a Dalek spacecraft.

On Skaro several styles of hoverbout were used to patrol the planet and the monitor events close to spacecraft. (COMIC: Legacy of Yesteryear)

A Dalek assassination squad sent in a Dalek time machine to kill the First Doctor and his companions used hoverbouts to obtain a better view of the Aridian desert. (PROSE: The Chase)

The Dalek invasion fleet preparing in the hangar to destroy the solar system with the Time Destructor was monitored from air on Kembel by Daleks in hoverbouts. (PROSE: The Mutation of Time)

Daleks aboard transolar discs were used to patrol around Dalek-held planets and in groups to attack spacecraft. (AUDIO: The Human Factor) They were also used to attack the enemy human forces attempting to breach the Dalek-held facility Project Infinity on Lopra Minor. (AUDIO: Project Infinity)

In an alternate timeline, President Nigel Rochester owned a functioning transolar disc, which he used to take the Sixth Doctor on an aerial tour of London. The vehicle was later destroyed by Rochester, who claimed that it was "bugged" with a listening device. (AUDIO: Jubilee)

Transolar discs were salvaged during a war between Daleks and humans and were investigated at Station 7. (COMIC: The Only Good Dalek)


 * Later Daleks showed the ability of flight without Transolar Discs. (TV: Remembrance of the Daleks, Dalek, among others)
