KANSAS CITY, Mo. -- Arrowhead Stadium was the site of two world record attempts on Sunday. A picture perfect day saw 49 planes dot the sky in arrowhead formation with a vast ribbon of pink smoke trailing behind as the National Anthem concluded. Then it was all about the fans bringing the noise.
The volume inside Arrowhead Stadium was unprecedented as the Chiefs Kingdom produced 137.5 decibels of noise. According to the Guinness Book of World Records, Arrowhead Stadium now holds the record as the loudest sports venue. It beat out Seattle's CenturyLink Field, which previously reached 136.6 decibels.
"I don't think I could have yelled any louder at my age," joked fan Ed Lydigsen.
Even before the game, fans knew they had the record in the bag. After all, it's fun to cheer for an undefeated team.
"Records are made to be broken. I'm sure that Seattle is going to jump right on it, but we'll jump back. We may set the bar so high they can't break it," said Milton Gange.
The other record attempted Sunday was for the largest flyover in history. Those 49 planes that flew over the stadium in an arrowhead formation are in the process of being certified by Guinness according to the Chiefs.
The other bonus Sunday, is, of course, that the Chiefs won! They remain undefeated with a record of 6-0 and are tied with the undefeated Denver Broncos for the AFC West division lead going into week seven.
All the records aside, ans are mostly just happy to have their Chiefs playing the way they are used to.
"It's great to come back here and have the stadium back to the way it was: rockin', " said Lydigsen.
