The story of the Bermuda Triangle field is one of the saddest in Hosovian history. Upon establishing an observation post on the remote planet of Terra, a Hosovian engineer was asked to erect a physical transformation field to keep the semi-intelligent Terrans away from the site. This is a fairly simple process that results in any wild Terran entering the field being instantly reversed along its primary horizontal axis, so that as soon as it enters, it finds itself leaving the field. The technique is used routinely throughout the galaxy.
Unfortunately, this Hosovian engineer was a former game designer. In Hosovian games, the Y-axis is inverted for historic reasons, which prompted a mistake resulting in all Terran vehicles emerging from the field upside-down. For a primitive vehicle, this is generally an unrecoverable condition, resulting in "ships" being capsized and aircraft pilots so disoriented* that they immediately dived into the sea**.
It took nearly fifteen Hosovian annums for the mistake to be discovered in a routine self-inspection. The horrified engineer immediately resigned its post and dedicated itself to making reparations to the Terran governments involved. A convoy craft carrying valuable technology was dispatched to the binary planet of the Terran system (referred to locally as Luna). Sadly, Terran colonization of their binary has been unusually slow, and the craft was forced to depart without the poor Terrans ever seeing it. The former engineer buried the cargo and placed a clear marker over the site, but it was mistaken for an unusual boulder by subsequent Terran explorer probes and never discovered.
