Boeing 747 flies Seahawks '12' pattern over Washington
Boeing is flying the Seahawks colors high over Washington.
The company painted a 747 freighter with the team logo and the Number 12 on the tail to salute the fans.
The plane rolled out of a hangar Wednesday at Paine Field in Everett. It flew to Boeing Field in Seattle on Thursday for a brief stop and then took off to fly a 12 pattern over Eastern Washington.
The flight was archived at the wonderful Flight Aware website.
