" Super Bowl Power Outage, 2013 With the world watching, half of the lights in the Superdome went dark in New Orleans during Super Bowl XLVII. Early in the third quarter, with the Baltimore Ravens dominating the San Francisco 49ers 28-6, a power surge into the 73,000-seat Superdome knocked out the power and delayed the game 34 minutes. During the break players meandered around, not allowed to leave the field. As of Sunday evening, &amp;quot;stadium authorities are investigating the cause of the power outage,&amp;quot; according to a statement from the NFL. After staying dark for most of the outage, the lights started to warm back up, with the ring of electric boards around half the stadium the final piece to come back to life. The 49ers were also involved in the last embarrassing NFL power outage, when the lights went off twice in their aging Candlestick Park in San Francisco during a 2011 Monday Night Football game against the Steelers. Montreal&amp;#039;s Olympic Stadium Concrete Collapse, 1991 Concrete falling has long been a problem at Montreal&amp;#039;s unloved Olympic Stadium. Most recently, in 2012 a giant concrete block fell at a parking facility at Olympic Stadium, though that didn&amp;#039;t stop the Montreal MLS team from playing at the stadium\u2014with that parking garage closed\u2014two weeks later. Back when Baseball&amp;#039;s Expos played in Montreal (they moved to Washington and became the Nationals), a 55-ton concrete beam fell inside the stadium in 1991 and forced the team out of Montreal temporarily. The Expos played their final 13 scheduled home games on the road. Kingdome Ceiling Tiles, 1994 While the Seattle Mariners were warming up to play the Baltimore Orioles in 1994, a pair of 26-pound acoustic ceiling tiles fell into the Kingdome&amp;#039;s seats. Thankfully, gates were not scheduled to open for fans until a half hour later, so the tiles to fall on vacant chairs. Water had been a major headache for the Kingdome even before the venue opened in this rain-dampened city. Stadium officials had tried to fix the problematic roof by sandblasting off the original roof coatings in 1993, but that may have caused more water issues, leading to the collapse. After the collapse, the Mariners went on the road for the final 20 games of the season and the NFL&amp;#039;s Seattle Seahawks had to play their first three home games at the University of Washington&amp;#039;s Husky Stadium. The Kingdome roof repairs cost over $50 million, and two workers lost their lives as the result of a crane accident during the fix. The Kingdome was demolished in 2000. Metrodome Roof Collapse, 2010      The Metrodome had its share of haters long before the roof caved in. But in 2010, dome had its most infamous flop when the Teflon top couldn&amp;#039;t bear the weight of 17 inches of snow and collapsed\u2014while the stadium was empty, fortunately. No one was hurt but the Vikings moved their remaining home games for the season to an alternate stadium. Heavy snows had caused three prior roof tears in Metrodome history, the most recent coming in 1983, which forced a delay in a Twins&amp;#039; game. Crews had tried to clear snow from the roof the day before the 2010 collapse, but work was suspended over safety concerns during the blizzard conditions. A security camera captured the snow breaking through the north end of the stadium, leaving the torn roof flapping in the weather and snow littering the artificial surface. Bastia Stadium Collapse, 1992 A temporary addition turned tragic when 18 people were killed at Armand C\u00E9sari Stadium in Bastia, France, in 1992. Trying to maximize fan enjoyment, SC Bastia added additional grandstands to the stadium, upping total venue capacity by about 50 percent. But as fans poured into the temporary stadium, a terrace collapsed, killing 18 and injuring more than 2300. Bradford City Fire, 1985 Fans love historic, traditional stadiums. But they easily can turn into rickety, run-down venues. That may be what happened at Valley Parade in Bradford, England, in 1985. A small fire broke out at the wood-built stadium\u2014complete with piles of debris under the stands\u2014and high winds helped fan the flames over the course of just four minutes, trapping some spectators and sending others fleeing. The fire killed 56 and injured another 265. The Fog Rolls in at Boston Garden, 1988      You need air conditioning in Boston if you want to play hockey in May. Just ask the NHL&amp;#039;s Boston Bruins and Edmonton Oilers. During Game 4 of the 1988 Stanley Cup Finals, the warm temperatures caused the ice to start evaporating, creating a fog at ice level that made it difficult for the teams to see. Shortly thereafter the condensation in the arena wreaked havoc on the electrical systems and the power went out in Boston Garden, canceling the game. More Boston Ice Issues, 2010 Boston&amp;#039;s TD Garden, where the NHL&amp;#039;s Bruins and NBA&amp;#039;s Celtics play today, is a more advanced venue than the old Garden. But it still has melting problems. During a regular-season contest between the Celtics and Los Angeles Clippers in 2010, officials delayed the game in the first quarter because continual wiping of the floor couldn&amp;#039;t get the wood dry\u2014turns out the ice hockey surface beneath the court has releasing water that became condensation on the basketball floor. The delay didn&amp;#039;t last, as crews continued to hand-wipe the floor during breaks and the ever-dropping temperature in the arena helped stave off the ice melt.  A Fire in Seattle, 2007 With the Kingdome already gone, the next aging Seattle sporting venue\u2014Key Arena\u2014saw its own near-disaster when a fire delayed a game between the SuperSonics and Golden State Warriors in 2007. During a timeout midway through the first quarter, a fire started from the underside of the massive overhead scoreboard when a spotlight ignited and smoke started shooting upwards. The game was delayed as crews laid out a tarp on the court and lowered the scoreboard, and firefighters used extinguishers to put out the fire. The spotlight was removed and game resumed. Mystery Slickness, 1999 It took over an hour for crews to figure out how to clean off a mystery chemical from the Reunion Arena floor in Dallas in 1999, allowing the NBA to resume its Dallas\u2014Phoenix game. The trouble was blamed on a solvent spill when the wood floor was stacked and stored for a hockey game. Players walking through the spill zone tracked the slickness around the floor.
