The cube wasn't particularly impressive in its construction, but those eight intelligent students, upon entering and remaining inside for a full 14 days, appear to have lost all sense of place and time and to have experienced something which they couldn't explain.

Curious details from the letters include the fact that after walking to the cube for several hours they found bottles of water waiting which were freshly chilled and which had hand prints in the condensation on the surface of the glass. Frederickson had told his pupils that he was a scientist working for an organisation called the LDD Reserach Group; the account of the chilled water bottles plus references to hearing vehicles moving around outside the box indicates that Frederickson may, indeed, not have been working alone.

The police officers who attended the scene described the cube as 'fairly well built' out of plywood bolted to a steel frame but said they doubted one man could construct it alone.

One of the eight students, Jacqui Bligh, had been instructed to tell just one person, her sister Samantha Bligh, that they were headed into the Great Basin Desert. She was told to reveal this fact to her parents and to police after 14 days and had been convinced by Jacqui that their disappearance was linked to a secret government project that would have massively important 'intergalactic' consequences.

Her sister had kept the secret for twelve days, but with parents and families becoming more and more distraught about their missing sons and daughters, her conscience could stand it no more and she divulged what she knew; first to her parents and then to the police.

It took them two days to find the cube in the desert. But when they got there it was empty except for eight letters left neatly on the floor waiting to be found. Neither George Frederickson or his students were ever seen again. The letters explained why.
