Corrected entry: The extrapolated shield covers the TARDIS and about 3 metres in front of it (it isn't even centred on the TARDIS), thus stopping Dalek lasers. The Doctor and co immediately walk out of this range and out of the cover it provides and spend the next few minutes talking outside this shield. Crazy and trigger-happy Daleks don't resume shooting or attempt to shoot at any point they are outside this shield, even the emperor doesn't take a shot. Side note: This shield can be walked though! Why didn't the Daleks move a metre forwards and resume firing. Daleks are known for their hyper-intelligence and a need to exterminate anything different, these Daleks seem more interested in being a bullies or parrots.
Corrected entry: The reference to the UK needing special "secret launch codes" from the UN is a compete fiction. The UK could launch a nuclear strike without needing permission from the UN. The UK would, however, need permission from the United STATES [not United NATIONS] to launch a nuclear strike, as the Polaris missiles are leased from the US Government [although the UK owns the warheads].
Corrected entry: Written on the side of the German bomb Jack is sitting on are the words "Schlechter Wolf. which is a mistranslation of the English "Bad Wolf. It should have been "Böser Wolf. Böse = bad, as in evil. Schlecht = bad, as in rotten, as in 'the milk has gone bad'. You are unlikely to say that the milk has 'gone evil'
Corrected entry: Capt. Jack Harkness introduces himself as "American Volunteer, 133 Squadron, Royal Air Force". It is an historical fact that there was such a squadron, made up of American volunteers.but it was not formed until August 1941. The events in "The Empty Child" and "The Doctor Dances" are supposed to have taken place during the "Blitz" on London, which lasted from October 1940 to May 1941. Capt. Jack could not be a member of an RAF squadron that didn't yet exist.
Corrected entry: Any security system worth its salt would stop accepting codes after too many incorrect ones have been entered. This is pretty much standard for security software, even today. No security system of the future would be written so badly as to just allow millions of combinations to be sent one after the other so quickly. The Dalek should really never have been able to get out as the door panel should have blocked after three or four invalid codes were entered.
Corrected entry: After the Slitheen realize that the Doctor's ruse with the alcohol is a ruse, the metal shielding around the windows and doors slams shut quite quickly. Later, while talking with the Slitheen again, the shielding closes much slower. Seems like their motors run at speeds determined by the dramatic tone of particular scenes.
Corrected entry: Rose's mum phones the Alien hotline and tells them all about the Doctor. She says that he's called the Doctor and has a Blue Box, fair enough. But then she says he called it a TARDIS. Except that no one called it a TARDIS in front of her. The closest was Mickey calling it "that box thing"
