Jones' awards include two Air Medals with combat 'C' devices. During a press conference Friday, 115th Fighter Wing commander Col. Bart Van Roo said he has suspended flight operations at the wing indefinitely amid the ongoing investigation into the cause of the crash. "It is grounded based on what we determine to be a safe time for us to fly again," Van Roo said. Determining the causes of the crash and other contributing factors could take months, Van Roo said, according to the Wisconsin State Journal. Jones' F-16 crashed around 8 p.m. Tuesday in the Hiawatha National Forest, roughly 300 miles northeast of the base, during a routine night training mission. The wing had planned to conduct night drills Monday through Thursday, according to unit announcements.
