This is a (albeit understandable) misspelling on the caption. "Lt. W.P. Irwin" should be spelled, "W.P. Erwin." This is a photo of American Fighter Ace William P. Erwin. Bill Erwin would go missing (and presumably drowned) during the ill-fated Dole Air Race from Oakland, CA to Honolulu, Hawaii. Erwin was piloting a Swallow airplane named "Dallas Spirit." Erwin and navigator Alvin Eichwaldt failed to return from a search for two other missing competitors, the Miss Doran and The Golden Eagle, and is presumed to have perished on 19 August 1927.
