Spitfire
A Supermarine Spitfire was a type of aeroplane used by the British during World War II.
Winston Churchill sent three Spitfires into space to fight the Dalek ship. The Spitfires managed to fly into space with the help of a Gravity bubble and were armed with laser weapons, based on technology created by Dr. Edwin Bracewell. Their mission was to destroy a beacon on the Dalek ship which illuminated London, leaving it vulnerable to German attack. Two Spitfires were destroyed but the last one, "Danny Boy", succeeded. After successfully completing his primary mission, the Doctor ordered him to proceed to destroy the Dalek ship. However, the Doctor reversed these orders when the Daleks threatened to destroy the Earth. "Danny Boy" then returned to Earth. (DW: Victory of the Daleks)
Though this advanced technology was intended to be dismantled to avoid altering history, it was utilised again when the Doctor summoned "Danny Boy" to Demons Run where he destroyed the facility's communications array, then returned to his own time. (DW: A Good Man Goes to War)
