Four army soldiers parachuting from a plane during an airborne training process were injured Wednesday when they fixed a wind gust and hit the earth hard, officials said.

3 soldiers suffered probable mild concussions, while the 4th complained of a strained neck muscle after landing at Rickenbacker International Airport, said David Johnson, a spokesman for the Army Reserve 412th Civil dealings Battalion in Columbus. The injured soldiers were taken to local hospitals.

The 3 Army Reserve paratroopers and one Ohio National Guard Special Forces paratrooper be taking part in a routine monthly jump that had 56 soldiers parachuting 1,250 feet from a C-130 military cargo plane, Johnson said.

The Ohio National Guard said the men jumped at on 1 p.m. from a plane that had flown from Pittsburgh.

The injured men "caught some additional wind and land hard," Johnson said. "The wind will catch it and the parachute won't deflate, and the paratrooper keeps going," are getting dragged.

Wind speed at the airport at the time was 15 mph, with gust up to 22 mph, said National Weather Service Meteorologist Jeffrey Sites. He said such speeds are not significant but would feel breezy.

One of the men landed on the airport tarmac, while the other 3 came down on the grass. The injured soldiers are ages 26 to 45.

Hard landings are not unusual during the monthly jumps, but the injuries are usually less serious, like sprained ankles and scrapes, Johnson said.

Rickenbacker is home to an Air National Guard base. It is mainly a cargo airport that also has a charter passenger incurable, and it is south of Columbus' main airport, Port Columbus International Airport.
