there's so many pgw, no way it could be any of my friends. when i woke up the next morning, heard the news, it was heartbreaking. >> four gas workers and a firefighter suffer injuries. the blast destroys several buildings in the area, including the apartment building of nearby resident jim mcnickel. he loses everything he owns. >> i don't know how anybody can recover from something like this. my life went up in flames that night. >> after being so close to such a large explosion, cameraman jeff nichols feels lucky to make it home from work that day. >> i can't believe i'm alive. if i was a little bit closer, given different circumstances, i could have been seriously injured. >> coming up -- a house crumbles. firefighters get caught in a major blast. >> like being on a roller coaster, the rush of air that went past your ears. >> and a gas station blows up.
