The harrowing incident occurred at dusk Saturday, when two planes carrying a total of 11 people collided at an altitude of 12,000 feet and one of the planes broke apart.
The skydivers told the Duluth (Minn.) News Tribune they were fortunate they were in the process of making their jumps when the planes collided.
"If we'd been back in the rear of the airplane when they collided it might have been a little bit different," instructor Mike Robinson said.
The four passengers of the Cessna 182 that broke apart had already exited the aircraft and the pilot was able to bail out and parachute to safety, the News Tribune said. The second plane landed safely after its five passengers also jumped.
Both planes were owned by Skydive Superior.
