Alaska Airlines is joining forces with the non-profit Alaska Seafood Marketing Institute to create the world’s largest king salmon.

Stretching nearly 129 feet, the fishy design will be put on a Boeing 737-800 and hit the skies this fall. The design for the new “Salmon-Thirty-Salmon II” is based on an earlier version that was painted onto one of the airline’s 737-400 planes in 2005 and covered over with the airline’s familiar Eskimo livery last year.

Here’s a photo taken by Jeffrey Milstein of the belly of the airplane sporting that first fish.
