During a November 18, 1979, matchup between the Seattle Seahawks and the New Orleans Saints inside the Kingdome, one of the stranger incidents in NFL broadcast history unfolded on live television.
In the middle of the game, a loud explosion echoed through the concrete dome, sending smoke billowing from near the New Orleans Saints’ sideline. The sudden blast shook the lower bowl stands and startled players on the field, prompting officials to temporarily halt play. Broadcast cameras captured Kingdome security officers and local police actively scanning the stands and sidelines trying to identify where the blast originated.

The explosive was determined to be an oversized commercial fireworks device or improvised salute charge brought into the stadium by a spectator. Fortunately, despite detonating in close proximity to the Saints’ bench and sideline personnel, no players, staff, or fans sustained injuries. Despite police efforts to track down the perpetrator during the game, the suspect responsible was never identified or apprehended.
Once order was restored, the Seahawks regained focus and dominated on the field. Led by quarterback Jim Zorn, who threw four touchdown passes—including two to Hall of Fame wide receiver Steve Largent—Seattle pulled away to secure a 38–24 victory. While Zorn’s 384-yard passing performance led the sports recaps the next morning, the mystery of the Kingdome sideline explosion remains a bizarre chapter in Pacific Northwest sports lore.
