In a west Texas town, employees in a medium-sized warehouse noticed the smell of gas. Sensibly, management evacuated the building, extinguishing all potential sources of ignition -- lights, power, etc. After the building had been evacuated, two technicians from the gas company were dispatched. Upon entering the building, they found they had difficulty navigating in the dark. To their frustration, none of the lights worked. Witnesses later described the scene of one of the technicians reaching into his pocket and retrieving an object that resembled a lighter. Upon operation of the lighter-like object, the gas in the warehouse exploded, sending pieces of it up to three miles away. Nothing was found of the technicians, but the lighter was virtually untouched by the explosion. The technician that was suspected of causing the explosion had never been thought of as "bright" by his peers.
