Hoverbout

Transolar discs, also called hovabouts or hoverbouts, 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.

Daleks aboard transolar discs were used to patrol around Dalek-held planets and in groups to attack spacecraft. (BFDE: 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. (BFDE: Project Infinity)

On an alternate Earth, 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. (BFA: Jubilee)

Transolar discs were salvaged during the Dalek-human war and were investigated at Station 7.


 * It was established that the Daleks of the post-Last Great Time War were capable of flight in atmosphere and space without any external assistance, although a transolar disc like device was used by the New Dalek Empire. (DW: Journey's End)
