Flying Saucer Over The Factory



Flying Saucer Over The Factory
At a new circuit factory an employee heard a thud and saw a bright metal dome-shaped object falling from the sky. Where did it come from?
Mysteries of Science

Transcript


At a new factory, circuits were made by printing conductive ink onto plastic film. The inks dried to hard, but flexible, electrical conductors. This process eliminated significant waste.

The ink had a small amount of solvent that evaporated into the air. But it was well below the permitted 5%The highly automated plant had a screen printer that automatically picked up sheets of plastic, fed them through the printing mechanism, and off loaded each one onto an oven conveyor.

The oven fire box was on the roof and fed heated air through duct work to the heating tunnel inside the plant. An employee in the parking lot heard a slight thud and saw a bright metal dome shaped object falling from the sky.What was this flying saucer over the factory and where did it come from?

Here's the rest of the story.

The oven heater on the roof had malfunctioned. The gas had come on, but the igniter did not immediately fire up.

When the igniter finally fired, the small explosion blew the rain shield off the roof vent pipe that looked like a flying saucer to the surprised observer in the parking lot.;
