Rather poorly disguised as a US Coast Guard HC-131A, this is in fact a civilian CV-240. She first served with Swissair as HB-IRT, and then briefly with Transocean Air Lines as N1018C. Having become N280P she was for some reason seized by the sheriff of Salt Lake County in 1975. She was moved to Castle in 1999.
