At 7:15 a.m., crews began to release the air from the Hubert H. Humphrey Metrodome. The deflation process lasted about 35 minutes, marking the end of an era as Minneapolis looks toward the future $1 billion Vikings stadium that will take its place in 2016.
Come April, the entire stadium that originally opened April 3, 1982 will be gone.
First, the fans of the Dome were turned off, then the vents were opened to let more air out. The deflation went "as planned," the Minnesota Sports Facilities Authority said.
A Twitter account dubbed @deflationday was created to offer the eager public up-to-date information as the MSFA didn't want fans present during the deflation.
MSFA Vice Chairman Bill McCarthy thanked MSFA operators and mentioned the Dome went down safely.
Crews continued their work into the morning by taking down the roof, which will be cut into large pieces to be used as construction tarps.
Meanwhile, just across the street, Hubert's hosted a Dome Deflation Day party from 11 a.m. to 3 p.m. and offered fans $1.50 drafts, a price one may have seen on the menu in 1982. Commemorative shirts and hoodies were also for sale.
