Tannoy voice

The tannoy voice was a computer-controlled voice aboard the carrier ship taking lazars to Terminus. A flashing light in the ship's control room accompanied the voice, although it was heard throughout the ship. It announced the arrival of the ship at Terminus on behalf of Terminus Inc., directing all passengers with mobility to disembark and stressing that there was no return. It later announced the beginning of stages one and two sterilitation, ordering all personnel to disembark and all lazars to comply with the drones. It later announced that the ship was departing but, after Tegan thumped a console in the control room around the same time Turlough opened the door from the carrier ship to the TARDIS, corrected the announcement and stated the launch was aborted.
