What ever happened to the DHD from Solitudes?
Solitudes is the episode where Sam and Jack are stuck in the Antarctic with the second gate. That gate has a DHD. So we have 2 gates and one DHD.
In the course of the series the Russians end up with one of these gates and we learn that they have their own DHD that that was found during World War 2. In the episode 48 hours we borrow the Russian's DHD to save Teal'c. How come we didn't use our own, what ever happened to the DHD from Solitudes?
