GLENS FALLS- Manhole covers went flying again in the Capital Region Thursday morning.
This time in Glens Falls, morning airborne heavy metal was immediately followed by flames shooting up to 20 feet.
Witnesses say it looked like a scene from a movie.
Shortly after it happened, businesses were evacuated and National Grid was again left to explain why it happened.
National Grid said there was fire on the cable, and were gasses built up from insulation building up around the cable, and they ignited, causing an explosion.
The explosion shattered windows around local businesses.
There were no injuries.
The Police Department says that vehicle traffic to the area will be restored by Friday morning.
This is the 4th series of blasts in our area in just the past month.
The first happened Sept. 19 along North Pearl Street in Albany.
A burning cable sparked an underground explosion that blew a roughly three hundred pound manhole covers into the air.
Then, just a week later, another underground fire struck the same area, knocking out power to 3700 people.
Just a day later, underground blasts struck the city of Troy.
Firefighters say the fires on Fifth Avenue were caused by an electrical short in an underground wire.
National Grid says that none of the incidents were related.
