YARMOUTH, Maine (NECN) -- One day after a deadly explosion in Yarmouth, residents of the North Gables Condominium development are reflecting on how lucky they are to be alive.
The explosion, which the Fire Marshal's Office attributes to propane, leveled a two story condominium at 50 Gables Drive, killing the sole occupant, 66-year-old Peter Corey.
Incredibly, the couple who lived in the other half of that duplex at 52 Gables sustained only minor injuries.
When the condo blew up early Tuesday morning, Bob MacKay was walking up the driveway with his newspaper.
"Boom!!" he recalled. "It was just a brilliant flash of orange and yellow light."
He says pieces of siding and roof crashed down all around him while insulation floated down like snow.
Inside the couple's home, MacKay's wife Rosemary was in the kitchen putting on the coffee.
"It sounded like a bomb went off," she said. "It took me off my feet. I went up in the air, met the ceiling panels and shards of glass and we all came down together on the floor.
MacKay said he tried to get back into the house to call 911, but the door wouldn't open and all the windows were shattered. When he finally got inside, the phone was gone as well the table it used to sit on.
He says he yelled for his wife and the couple fled the crumbling condo together.
After realizing that they had survived a powerful explosion with only a few cuts and bruises, their thoughts turned to their disabled neighbor, Peter Corey.
After seeing that his unit was flattened down to its foundation, the couple said they knew there was no way he could have survived the blast.
While the MacKays condo is still standing, investigators with the Fire Marshal's Office said it is uninhabitable and will have to be torn down.
The MacKays and some of their neighbors will need to find new homes.
The blast also destroyed many keepsakes they've collected over the years.
"All our family treasures are in that house. said Bob MacKay. "We have nothing in storage. We've been married 50 years...so there are things that go way back."
They are now trying to focus on what they have, rather than what they lost--each other.
They know that even though their house will be torn down, their neighbors will hold them up, providing them with the support they'll need to move on.
