This happened about 2 years ago. It was your typical FOX special.
They opened a couple of never found before tomb. They last one they opened, the one with the most potential was flooded with water.
Of course they opened this tomb with about 4 minutes left in the show. They stated they had never seen anything like this before and were excited to drain the site and discover what was under the water.
I remember something like that, where they had a robot crawling through a tight tunnel. The big suspense was what was behind a door or hatch. They removed to find another hatch (woo!). I don’t remember any water, and seems like only about a year ago, so I bet this was a different show.
Yeah, Revtim, you are thinking of the follow-up to the original show. In the first, they explored the tunnels with a little robot, and found the hatch. Then they made a extension for that rover that could look thru a crack in the hatch and see to the other side, where they found(!)…the other hatch.
Both these shows turned up pretty much nothing new except a few new mummies, (which is almost a daily occurance during an excavation).
The Fox TV network teamed with the National Geographic Channel and did the program Pyramids Live: Secret Chambers Revealed last September. Some good shots of the robot in the shaft here.
I hate to say this since I find most archaeology interesting, but it really shouldn’t be shown live as so much of it is very slow careful work and study.
