CHICAGO (AP) — A U.S. Army skydiver who had served five tours of duty in Iraq and Afghanistan died Sunday from injuries suffered in a midair collision with another jumper during a stunt at the Chicago Air & Water Show, authorities said. 
 
 Sgt. 1st Class Corey Hood of Cincinnati, Ohio, who had recently turned 32, was pronounced dead Sunday afternoon at Northwestern Memorial Hospital in Chicago, said Mario Johnson, a Cook County medical examiner's investigator. 
 
 Hood had logged more than 200 free fall jumps and 75 military static line jumps during his career, according to his Army biography. 
 
 The Army Golden Knights and Navy Leap Frogs parachute teams were performing what is known as a "bomb burst" Saturday when the collision occurred, Golden Knights spokeswoman Donna Dixon said. During the stunt, parachutists fall with red smoke trailing from packs and then separate, creating a colorful visual in the sky. 
 
 Dixon said Hood collided with a member of the Navy's precision skydiving team. 
 
 Hood was knocked unconscious, "which resulted in an uncontrolled offsite landing," Dixon said in a statement. 
 
 Spectator Heather Mendenhall told the Chicago Tribune on Saturday that she was watching the show from a rooftop and saw Hood strike the roof of a high-rise building next door with his feet and then fall — his parachute trailing behind him. 
 
 "His legs caught the tip of the roof, and then he fell over. It was horrible," she told the newspaper. 
 
 The other parachutist, who has not been identified, landed on North Avenue Beach near the main viewing area for the show, Fire Department spokesman Juan Hernandez said Saturday. He was treated for a broken leg. 
 
 The accident is under investigation, the Army said. The team did not perform again on Sunday. 
 
 "The Knights are a very close knit team and the military skydiving community is equally close; we will support Corey's family and each other during this difficult time," Col. Matthew Weinrich, commander of the U.S. Army Parachute Team, said in a statement. 
 
 Hood served five tours of duty in Iraq and Afghanistan and had earned numerous awards, including two Bronze Stars. He is survived by his wife, Lyndsay. 
 
 Chicago Mayor Rahm Emanuel called Hood "an American hero," saying in a statement late Sunday, "He defended our freedom, he amazed so many as a member of the Golden Knights, and he will be missed." 
 
 Specialists such as the Army and Navy jumpers can reach speeds of up to 180 mph during freefall by pulling their arms to their sides. They typically open their parachutes at around 5,000 feet, joining their canopies together in formation and setting off smoke grenades to send red smoke trailing behind them. 
 
 The annual two-day air show draws millions of people to Chicago's Lake Michigan shoreline. Headliners included the U.S. Navy Blue Angels. 

 The Army parachutist injured during a weekend jump at the Chicago Air & Water Show died Sunday afternoon, according to the Cook County medical examiner’s office. 
 
 Sgt. First Class Corey Hood, 32, of Cincinnati, died at Northwestern Memorial Hospital one day after he was critically injured when he struck an apartment building and fell to the ground following a mid-air collision with another parachutist above the Lake Michigan shore. 
 
 The Army said he was knocked unconscious, resulting in a landing away from the air show. 
 
 He and a member of the Navy Leap Frogs jump team appeared to collide in the air after their teams performed a maneuver during a jump. The Leap Frogs member suffered a broken leg. The team members had formed a circle by holding hands in the air, then broke apart in different directions. It appears Hood and the Leap Frogs member collided at that time. 
 
 Hood, who served five tours of duty in Iraq and Afghanistan, began jumping in 2010 and logged more than 500 free falls, according to his online profile page. He enlisted in the Army about 10 years ago, eventually serving as a platoon sergeant and receiving two Bronze Stars, two meritorious service medals, five Army commendation medals, among other honors. He is survived by his wife, Lyndsay, the Army said in a statement. 
 
 Hood struck an apartment building on his way to the ground and underwent surgery Saturday to remove pressure on his brain after suffering a head injury, officials said.

 The investigation into why the collision happened is ongoing. 
 
 “Our focus right now is on supporting Corey’s family and grieving for our teammate,” said Lt. Col. Matthew Weinrich, commander of the parachute team. 
 
 Mayor Rahm Emanuel called Hood "an American hero," saying in a statement late Sunday, "He defended our freedom, he amazed so many as a member of the Golden Knights, and he will be missed." 
 
 In the aftermath, parachuting events were called off for Sunday’s show. 
 
 Air show attendees leaving North Avenue Beach after the event Sunday afternoon said they supported the decision by the Golden Knights and Leap Frogs not to perform. 
 
 “I was hoping to see the parachute guys today but I totally understand them canceling,” said Megan Bearder, of Chicago's Logan Square neighborhood. “I've been thinking about them and praying they'll be OK. My enjoyment of seeing the parachutes is nothing compared to the gravity of the situation.” 
 
 Phil Williams, of south suburban Crete, had a similar take. 
 
 “Accidents happen and I understand totally,” Williams said. “They did the right thing to cancel it.” 
 
 The jumps aren't without risk or occasional incident. Last month, a member of the Golden Knights team was taken to the hospital after a landing mishap in Wisconsin. In 2013, two Golden Knights were honored after risking their lives to save one another after their parachutes became tangled during a jump in Florida. 
 
 According to the Golden Knights website, the last parachute jumper to be killed was in 1980, when Sgt. First Class Thomas Johnson died while performing a stunt at an air show in Fredericksburg, Va. 
 
 News reports describe Johnson and another member of the Golden Knights team leaping from a plane from about 10,000 feet, then Johnson plunging to his death after both his main and reserve parachutes failed to deploy in time. Johnson’s parents, brother and several other relatives were among the spectators when the disaster occurred, news reports stated. 
 
 Several performers have died while performing at air shows around the world this summer, according to news reports. 
 
 Missouri publications reported that pilot Steve O’Berg, of Smithville, Mo., died June 27 after his biplane crashed at an air show in Cameron, Mo. O’Berg, 50, had been trying to perform a stunt and crashed into several trees. 
 
 A 39-year-old pilot died in a crash during a show in northwest England on Aug. 1. A day later, a military helicopter performing in an air show southeast of Moscow crashed, killing one of the pilots on board.

– Tragedy for the Army's Golden Knights: Sgt. 1st Class Corey Hood, a parachutist who served five tours in Iraq and Afghanistan and earned two Bronze Stars, has died from injuries suffered at the Chicago Air & Water Show. A Golden Knights spokeswoman says the 32-year-old from Cincinnati was knocked unconscious after colliding with a member of the Navy's Leap Frogs parachute team on Saturday, the AP reports. He clipped the top of a high-rise building and had what the spokeswoman calls an "uncontrolled offsite landing." The Navy skydiver was treated for a broken leg. Hood's death is believed to be the first Golden Knights fatality since 1980. Hood logged more than 500 free falls after he started skydiving in 2010, the Chicago Tribune reports. He was "an American hero," Mayor Rahm Emanuel said in a statement. "He defended our freedom, he amazed so many as a member of the Golden Knights, and he will be missed." The Golden Knights and Leap Frogs called off jumps scheduled for yesterday, which air show attendees thought was the right call. "I was hoping to see the parachute guys today, but I totally understand them canceling," a Logan Square resident tells the Tribune. "I've been thinking about them and praying they'll be OK. My enjoyment of seeing the parachutes is nothing compared to the gravity of the situation."
