On this date Oct 26th

A look at the memorable moments in Seahawks history that occurred on Oct. 26:

1997: Warren Moon, at the age of 40, passes for 409 yards and five touchdowns in a 45-34 win over the Raiders at the Kingdome. Three of the TD passes go to Joey Galloway. Moon’s 409 passing yards prove to be the single-game high in the NFL for the season.

2008: Mike Holmgren collects his 172nd regular-season victory to move into sole possession of the 10th spot on the NFL’s all-time list as the Seahawks defeat the 49ers 34-13 in San Francisco – where Holmgren grew up and also coached.

I'm having trouble remembering that game for Moon. The only one I can remember is the Monday nighter where there was lightning storms and stuff in KC, and the game was delayed by an hour or so, "the water bowl"
