Theory:Doctor Who television discontinuity and plot holes/Victory of the Daleks


 * the zeppelins seen in this episode look nothing like those seen in the Empty child/The Doctor dances.


 * Different type/model? Different area of London?


 * The barrage balloons seemed to be tethered at the wrong height as well - the point was to force aircraft to fly high over them rather than risk knocking a wing off on the supporting wires. Having them flying lower than the tower of Big Ben makes no sense unless they had been reeled in for some reason.


 * How did the spitfires survive in space? surley the glass would have smashed.
 * The planes are seen with a bluish field around them, presumably an effect of the "gravity bubble" or some other piece of Dalek technology. It may have something to do with the glowing yellow spheres seen inside the cockpit. Such technology would also help explain how they can still fly, since their engines and propellers would normally be useless without air. At any rate, it's clear a good deal of alien tech has been applied to them, further supported by the presence of some sort of laser weapon system. And don't call me Shirley.
 * Perhaps more to the point, how did they have time to modify three Spitfires in what appears to be mere minutes of in-story time from "It could work in theory" to "pew-pew-pew".


 * if the daleks led Bracewell to believe he created the daleks and they planted him in gthis location then at what point was he meant to have created the daleks? did Bracewell apparently come to Churchill with the "ironsides" or did they appear one day and Bracewell claimhe had been working on them?
 * The Daleks appeared and Bracewell had the memory of creating them.
 * Ultimately, it doesn't necessarily matter for the story what the exact chronology was.


 * why did the daleks give Bracewell the idea for anti-gravity technology? did it help them at all?
 * The Daleks were not selective in what ideas they gave him. (Or the anti-gravity technology is used for Dalek flight, so it was part-and-parcel of the how to build a Dalek idea.)
