"We hear this big rumble," he said. "There was no explosion initially, and my roommate who was actually outside, runs inside and said, 'A plane just crashed into our back yard!'"

"We didn't know what to do," Grondines said. Since they had not seen any fire, they decided to go back outside and help.

"And then it exploded," Grondines said. "If that second explosion had happened a little later it could have been really bad."

The students, four of whom live together, believe he flew to avoid crashing into their home just south of the Publix grocery store on Rosewood Avenue.

"I'm sure that guy has passed, but if his intention was to land where it wouldn't affect anyone else, he did a great job," Grondines said. "It's definitely tragic what happened, but we are definitely counting our blessings."

The Columbia Fire Department tweeted photos of an extensive response operation around downed tree limbs.

The coroner's department is involved but the Fire Department did not comment on the occupant of the plane.

"The crash did cause one home to catch on fire," the department tweeted. "The occupant of the home did suffer a minor injury unrelated to the crash. The fire is now out."

Shelby Beckler, also a USC student who lives nearby, said small planes like this are common at Columbia's Jim Hamilton - L. B. Owens Airport.
