Witness to Gas Explosion 'Thought the World was Ending'
Residents of Sissonville, West Virginia are surveying the damage left in the wake of Tuesday's massive natural gas explosion.
The explosion was reported just before 1 p.m. Tuesday.
The fire destroyed four homes and at least five others have been damage.
Several people were treated for smoke inhalation, but no one was seriously hurt.
The blast charred several hundred feet of Interstate 77, shutting down traffic in both directions for hours.
A team with the National Transportation Safety Board arrived in Charleston late Tuesday night to investigate the incident.
Officials say the mission is to find out what happened and why it happened to prevent future accidents from happening.
