Why take the Great Circle route to Australia when you can tunnel through the very molecules of the solid earth itself in a TAU-mode shuttle? When a routine TAU-shuttle becomes entombed in solid rock miles under the earth, the only means of rescue may be the wildly experimental LAMBDA-mode shuttle; and even its creator has no idea how it will behave, or whether its pilot can keep his sanity during the rescue mission.
