Yes, incredibly cool. And the rumor (if we can believe rumors) is that they actually recovered quite a bit more, but are holding back, either because the BBC doesn't currently have copies yet, they don't want to infringe on current DVD sales (in the case of the recent Ice Warriors or Tenth Planet DVD's), etc.
Both of these stories are now getting a DVD release and are available on ITunes.
There is also speculation as to what else (ie non Doctor Who) they found.
Enemy of the World and Web of Fear are back-to-back stories from Troughton's 2nd series. The Ice Warriors is the story before Enemy of the World and the BBC recently released this as a DVD with the 2 missing episodes in cartoon form with original audio. Yes, so I wonder if they found either of the two missing stories of Ice Warriors as well.
One wonders why they have been so secretive about this; they must have found these episodes months ago as they have already remastered them for DVD.
Presumably same with the Web of Fear. However, if you don't want to pay/wait for Web of Fear you can watch it on Virgin's on-demand catch-up service for free (if you have NTL/Virgin cable). Not sure if this will be same quality as the forthcoming DVD though.
