Arctic Station 39 Disaster
At 03:22:07 am in Y1S1 NESC, LEIGH&CO scientists detonated an Artmeis mk4 mainline Mining Bomb, 8kt nominal yield, s/n:28-762 at its Arctic Station 39 in Shaft B as part of its efforts to develop a new version of this device. From what little is in the public record, and some second hand reports from an Eskimo that witnessed the event from a neighboring village, it appears that the device misfired. All hands on the station, and within a 0.204166(repeating) km distance from the epicenter of the blast, vanished in a flash of light.
Spokesperson Miguel Vector, who had brought a puppy to the press conference, was reported as saying "These things happen. Look! A puppy!".
The station remains abandoned to this day, and is the occasional destination for extreme adventure tourism, despite LEIGH&CO's perfunctory cautions not to visit the area.
