In late 1990, the service tunnel was almost complete. The moles had approached each other closer to the British end. France, however, didn't gloat in its accomplishments. Both countries had come together for a common good. This isn't to say that some friendly competition hadn't fueled the tunnel's construction. When the two tunnel boring machines were about 50 meters from each other, the English moles drove off-line to the right into the narrow gap between the service tunnel and the running tunnel south (Fetherston, p. 342). The British machine stopped once it lay parallel and head to tail with the French machine. The English mole was stripped of anything salvageable. It was then entombed within concrete. The French tunneling machine than was hollowed out. Its outer shell would serve as the tunnel lining. Two workers, one from each side, were chosen at random to be the first to cross over from their respective tunnels and into the other. On December 1, 1990, British construction worker Graham Fagg and his French counterpart, Philippe Cozette, each with an air spade, drilled through the final piece of rock which stood between them (See Appendix C). Once the hole grew big enough, Cozette poked his head through to a frenzy of photographers, reporters, and a small handful of privileged spectators. Fagg repeated Cozette's actions to the French side. News soon spread across the world. The United Kingdom and France were now linked for the first time in 8,000 years (Guterl, p. 25). This gala event had come at the objection of TML. They felt as though the tunnel was already over budget, and the last thing Eurotunnel needed to do was celebrate. This single event, however, did appease skeptical investors in the project.

Turing machines are more like theoretical machines than things you'd actually build. (Though it has been done; check out aturingmachine.com!) However, there are many applets on the web that simulate turing machines. Try searching for some!
