Tyler Wojo told that story for years and the E-kit is recommended to all new hires during ground school. The E-kit consists of a plastic bag and TP. Other items are optional like, air freshener.
Wojo accomplished many feats of heroism in his day as a Great-Laker, another such tale involved using his Brazilia to intercept a meteor and halt impending distruction headed for the city of Dickinson, ND. If you are ever in Dickinson, or are passing through there is a plaque on the wall at the city hall with a picture of him accepting the key to the city.
