The Silence of the Cicadas - S1-E3
Factual error: The station at the Arctic would have storage batteries to retain a charge for when storms obscure the solar panels, yet, once the bats cover the panels, they lose electricity.
Suggested correction: The power drops out but later on in the episode they have backup power. The problem is that the bat that gets into the base then takes out the backup power.
Factual error: The episode states that there is border control between Germany and Czechia. There is no border control within the Schengen area of the EU (which includes Germany and Czechia). You can cross borders by car or fly in a plane without showing your ID.
Factual error: The home computer tablet controlling the alarm system shows June 11th, 2015 as a Wednesday. 06/11/15 was a Thursday.
Factual error: A scene in a photographic darkroom shows Michael Gambon developing a colour print in a dish under safe lights. Not possible. Colour printing must be carried out in pitch dark usually inside a light tight print processor, as colour photographic paper is sensitive to all wavelengths of visible light.
Factual error: In the transition shot showing Hobart Building in San Fransisco, items not belonging to the scene are visible and have not been edited out. These items include; modern phone numbers, web addresses for several companies and educational institutions, satellite dishes and American flags. (00:24:10)
Factual error: Possibly a mistake from the novel on which the series is based, but although he later became Bishop of Hereford, St Thomas Cantilupe wasn't baptised in Herefordshire. He came from Buckinghamshire.
