Planet (Attack of the Daleks)

The TARDIS once landed on a planet where the Second Doctor tested out his pedal-copter with his grandchildren, John and Gillian Who. Whilst flying, one of the blades broke and they flew out of control, crashing on a rocky outcrop. As they crashed they saw a group of asymmetrical Daleks. The Doctor, John and Gillian used the shattered pieces of rocks around them to attack the Daleks. They then used a large boulder to stop the Daleks from following them and used the Dalek's space craft to return to the TARDIS. (COMIC: Attack of the Daleks)
