What pattern did a Boeing 747 pilot fly over the state of Washington in preparation for Super Bowl XLVIII?

The number 12 signifies the crowd of Seattle Seahawks fans because they are “the 12th man” on the field. All around Seattle the week before the Super Bowl, businesses displayed the number 12 on signs – some skyscrapers even turned the entire building into a giant 12 sign. On Jan. 30, a pilot flew a Boeing 747 in the shape of the number 12 over eastern Washington state.
