"My heart just goes out to their families," said Crockett. "I can only imagine what it will be like to lose a loved one. I will be praying for their families."
Neighbor Robert Ferrigno said he heard a loud sputtering noise from the engine and then a boom.
"I looked out the front window, up the street, and there's flames coming out the house," said Ferrigno.
Ferrigno said the flames were as high as the surrounding trees, which are about 40 feet tall.
Ferrigno said house insulation was coming down from the sky like snow. He said the homeowner was already in a neighbor's garage across the street.
"Unfortunately things like that happen. Accidents do happen, but never this close to home," Ferrigno said.
Tim Hornsby lives next door to the Crockett's with his wife and 7-week-old baby.
"There's insulation and pieces of it all over my yard," said Hornsby. "I'll be cleaning up tomorrow."
Hornsby said he wasn't home when the plane crashed, but the rest of his family had to be evacuated.
"My wife was pretty upset, yes," said Hornsby. "She was upset after seeing the explosion. I didn't see the accident, but heard the explosion."
The FAA reported the plane was flying under visual flight rules, but weather conditions at the time in Flagler County showed a low cloud cover that would have required instrument flight rules.
"A pilot who flies a lot in Florida knows that the conditions can change dramatically very quickly," said Channel 4's Sam Kouvaris, who is an experienced pilot.
The plane was registered out of the British Virgin Islands. The Federal Aviation Administration and National Transportation Safety Board are investigating and will return to the scene Saturday.
What went into the house is no longer there, except for a portion of the tail wing. Investigators said they also removed the bodies from the wreckage Friday night and will determine how to get what's left of the plane out of the neighborhood.
