Bruno Taltalian
Bruno Taltalian was a scientist working at the space control center.
Professor Taltalian worked alongside Professor Ralph Cornish during the efforts to find out what happen to Mars Probe Seven. During his time there, he was frustrated and difficult almost to the point of being an obstruction. When the Doctor determined that the strange sounds were alien messages and had to be deciphered and recorded, he pulled a gun on him and Liz demanding that he turn over the tape of them. Later, when General Carrington came into the picture he said that he was ordered to take the recordings by him. But as the General was clearly involved in an illegal operation, he was drawn in deeper and deeper into his nefarious activities. He kidnapped Liz and brought her to Reegan, Carrington’s henchman to help them communicate with the captured aliens. Later, when the Doctor began to suspect him of being involved with the people causing all the problems, he went to Reegan to tell him of the Doctor's suspicions. Reegan seeing that Taltalian was in danger of being found out and beginning to waiver, he prepared a bomb in a suitcase to kill the Doctor and Taltalian. Taltalian brought the suitcase to the Doctor but not knowing that Reegan had set the bomb to explode immediately without the timed delay that Reegan spoke of, the bomb exploded immediately when he turned the levers on the suitcase. He was killed instantly but not the Doctor. (DW: The Ambassadors of Death)
