of . The stadium was the largest cable-supported dome in the world. Its roof was made of teflon-coated fiberglass fabric and had an area of . From its completion until the December 31, 1999 opening of the Millennium Dome in London, it was the largest hooked domed structure of any type in the world. Matt Hartley Lighting, LLC designed the lighting for the concourse of the Georgia Dome. Surface The Georgia Dome originally used AstroTurf artificial surface for its football events. In 2003, Arthur Blank, the new owner of Atlanta Falcons, funded the installation of the new infilled FieldTurf artificial surface system. Renovations In 2006, the Atlanta Falcons and the Georgia World Congress Center Authority announced a $300 million renovation to the Georgia Dome. The project was separated into two stages. The first stage, which took place before the 2007 NFL season, focused on updating the premium seating areas, including the creation of eight 'super-suites' as well as an owners' club, most of them now incorporating new plasma TVs. In 2008, the exterior of the stadium was repainted, replacing the original teal and maroon color scheme with a red, black, and silver theme to match the Falcons' team colors; the stadium's original teal seats were replaced with red seats in the lower and upper levels and black seats in the middle level. The entrance gates and concourses were also renovated and updated before the 2008 football season. In 2009, the video screens in both end zones were relocated to a new exterior monument sign on Northside Drive. The interior end zones each received a new and considerably wider HD video screen that significantly enhanced views of replays, as well as graphics and digital presentations. A new sound system was installed in the same year, replacing the previous system that was nearly 20 years old. In 2008, the Georgia Dome started showing safety videos before games, presented by Deltalina, flight attendant "mascot" of Delta Air Lines. The videos satirize Delta's massively popular "Deltalina" inflight safety videos. The videos' theme was "Delta Safety First". Major weather-related issues Three years after the completion of the Dome, the integrity of its roof became an issue. During a Falcons pre-season game in August 1995, a severe rainstorm caused water to pool on the fabric, tearing part of the material, and causing a section of the roof to fall into the stadium. The storm was intense
