The only survivor of the crash is medic Joe Paoletta of Brecksville. Besides flying in the helicopter medivac team, the father of two also worked at Firehouse Number One in Cleveland Heights.
Paoletta's two co-workers, pilot William Spence of Marshalville and veteran flight nurse Kelly Conti, both died instantly when the chopper fell 12 stories and exploded.
Throughout the day, a team of investigators checked the mangled wreckage, looking for answers.
NTSB investigator Leah Yeager says the pilot did contact the tower at Burke Lakefront Airport in preparation for departure. Burke responded to the pilot, but he never answered back.
This is not the first fatal crash involving the BK-117 helicopter. Since 1990, there have been six fatal crashes involving the choppers. 14 people have been killed in those crashes.
Paoletta is currently at Metro Hospital with burns over 30 percent of his body. Friends of Paoletta believe it was a miracle that he was able to drag himself away from the wreckage.
The NTSB hopes to have its first report ready to go in the next five to 10 days. They will begin reviewing the maintenance logs by Monday.
