Bus
From Tardis Wiki, the free Doctor Who reference
Buses were a public transportation vehicle used on Earth. (DW: Rose)
Nostalgia Tours converted a space cruiser to have the chassis of a bus when it was due to travel to Earth, 1959. It was capable of flight and was powered by a Hellstorm Fireball engine. It was destroyed by the Bannermen. (DW: Delta and the Bannermen)
The 200 was a London double-decker bus, it fell through a wormhole with its sturdy construction protecting the occupants. The Doctor fitted it with anti-gravity clamp clamps making it capable of flight; it was then able to be returned through the wormhole to Earth. Lady Christina de Souza then flew off in it. (DW: Planet of the Dead)
