A new film explores the events surrounding one of the world's most enduring UFO mysteries.
The incident began on December 9, 1965 when thousands of witnesses across several states observed a peculiar fireball which dropped 'hot metal debris' as it blazed through the heavens.
Despite the sightings being fairly widespread however it was the small town of Kecksburg in Pennsylvania that would become most closely associated with the incident.
It started when a young local boy claimed that he had seen the object landing in nearby woods and his mother later reported it to the authorities when she saw strange blue wisps rising from the trees.
Several locals including members of the fire department went out to investigate the scene and came across an odd acorn-shaped object the size of a small car with strange writing on its surface.
Within a short space of time there were reports of an intense military presence at the crash site with army officials ordering civilians away from the scene while the object was being loaded onto a truck.
The incident was later played down as nothing more than a meteor impact, however many people still believe that the military had been covering up something a lot more significant.
To this day, no definitive explanation for what happened has ever been found.
Over the years numerous documentaries about the case have been released and 'Kecksburg' - a docu-drama of the incident created by director Cody Knotts - is perhaps the most compelling yet.
It was completed with the help of crowdfunding support and screened in select theaters in September, however a wider release is expected early next year.
Until then, you can check out a trailer for it below.
