It All Makes Sense Now

Something I've wondered about Doctor Who for a while now: if the Doctor is running around for years with UNIT, why didn't Torchwood show up even once? Turns out they didn't have to: dwcanon_fodder: Torchwood, UNIT, the Forge, and ICIS: "This also explains why Torchwood did nothing about the Doctor when he was working for UNIT: they could easily keep an eye on him, and use his knowledge without tipping their hand. The British Rocket Group continues to operate under Bernard Trainor, and uses Torchwood-acquired technology to propel Britain to the front of the space race."
