Mike Robinson was on the step outside the plane, 12,000 feet above ground, just seconds from making the 937th sky dive of his career, his final jump of the day.
Then came "that terribly loud bang," he recalled Sunday.
The wing and its supporting strut, just a few feet from Robinson and three other jumpers, exploded into a fireball over northwestern Wisconsin, 8 miles southeast of downtown Duluth, early Saturday evening. A second plane, carrying five other sky divers, had collided with Robinson's plane, sending the jumpers into a premature free fall.
What followed, said Robinson, an experienced instructor and safety adviser for Skydive Superior LLC, was "nothing short of miraculous."
Authorities on Sunday still didn't know what caused the accident. The lead plane broke into three pieces and one of its wings had yet to be located Sunday afternoon, said Roland Herwig, a spokesman for the Federal Aviation Administration. But as investigators from the FAA met with officials from Duluth and Superior, Robinson, 64, spoke of falling from the sky while dodging debris as nine jumpers and two pilots landed safely, with little more than a few cuts and bruises. One pilot managed to guide his plane safely to the runway, while the other bailed out of his doomed plane using an emergency parachute.
"We call it our sunset load, the last sky-dive of the day," Robinson said. "The sun was getting low on the horizon, still daylight. Beautiful blue skies. Just a perfect setting to make the last dive of the day."
On board with Robinson in the lead plane were Barry Sinex, 54, of Duluth; LaNaya Bonogofsky, 31, of Superior, and Johnny Rodorigo, 26, of Duluth, all experienced sky divers, individuals who had each jumped between 300 and 2,500 times, Robinson said. All are passionate about their sport, Robinson said, and Rodorigo agreed. Two years ago, Sinex even wrote an essay for Parachutist Online entitled, "How Skydiving Changed My Life."
Saturday's experience could have been life-ending, Robinson said.
