( CNN ) -- Life goes on for people who jump out of airplanes , even a day after two fellow parachutists died when their canopies apparently became entangled . Jumps continue at the Parachute Center , where two parachutists died Sunday . On Monday , the Parachute Center near Lodi , California , was open , just like it is any other day . The two jumpers who died Sunday had taken off from the parachute facility in central California . `` Everybody 's sad . Everybody 's unhappy , '' said Parachute Center owner Bill Dause . `` But everybody here is here because they enjoy jumping . Neither one of them would have wanted us to shut the doors , '' he said , referring to the jumpers who died Sunday . The San Joaquin County Sheriff 's Office received a 911 call for assistance at 12:53 p.m. Sunday , said Deputy Les Garcia . The sheriff 's spokesman confirmed there were two deaths , but referred questions to the Federal Aviation Administration . `` We 're investigating , '' said FAA spokesman Ian Gregor , adding that two investigators were on their way to the jump center . The inquiry could take months , Gregor said . `` One of the main things we want to do is get a hold of a video that was supposedly taken , '' Gregor said . The FAA has purview over such issues as how the parachutes were packed -- by whom , when and how -- and whether weather conditions were correctly considered . `` Obviously , in a situation like this , we certainly want to look at how the parachutes were packed , '' he said . `` But it 's possible that what happened is beyond our regulatory capability . '' Garcia said he could not identify the two victims . `` The ID and notification of next of kin is pending , '' he said , because `` one of the victims has two names . '' Parachute Center owner Dause and media reports have identified the victims as Robby Bigley and Barbara Cuddy . They were among eight parachutists from a competition team who jumped from an airplane at 9,000 feet to practice making a `` canopy-relative formation , '' a maneuver in which they stacked parachutes near each other to form a wedge , Dause said . `` The last two individuals docking experienced canopy problems , '' Dause said . One jumper 's chute rotated into another jumper 's canopy and they smacked into a third parachutist , Dause said . The third parachutist managed to wriggle free , Dause said , but the other two remained entangled and spiraled down from 5,000 feet . They were unable to deploy their reserve chutes . They landed in a vineyard , Dause said . One victim was dead at the scene and the other died at a local hospital , reports said . Bigley and Cuddy are listed on the United States Parachute Association Web site as national record holders for formation jumps . Bigley 's record jump occurred this year and Cuddy 's in 2007 . The jump team was preparing for a national competition in October . According to the United States Parachute Association , there were 30 skydiving fatalities last year . No figures were available for this year . The most fatalities occurred in 1998 , when 44 people died . The fewest in recent years was in 2007 , with 18 , according to the association . Dause said there have been previous fatalities at the Parachute Center , but he did not elaborate . `` We 've been open for a long time , '' he said .
