Invaders from Mars (audio drama)

Invaders from Mars is a Big Finish Productions audio drama based on the long-running British science fiction television series "Doctor Who". This audio drama was later broadcast on BBC 7 in four weekly parts (starting on 29 October 2005) and was later rebroadcast on the same channel once more (beginning on 19 November 2006).
Summary.
In Manhattan 1938, the Eighth Doctor and Charley meet a crooked gangster, a Russian spy, a sinister fifth columnist and Orson Welles. Welles's broadcast of "War of the Worlds" is just a story, but maybe there really are aliens at loose.
Deliberate errors.
The second season of Eighth Doctor audios featured a number of deliberate errors:
The first two "mistakes" in this list were deliberate, intended to be examples of anti-time contamination. The third was also deliberate, but was explained in "The Time of the Daleks". The last was not deliberate but was later retconned to be another example of anti-time contamination.
Another possible example of anti-time contamination is the date. "The War of the Worlds" aired on 30 October 1938, yet, when he asks what day it is, the Doctor is told that it is 31 October 1938.
