The airship was flying rapidly "down wind" at an altitude of about two hundred feet. As it passed almost overhead the fuselage appeared to scrape the _Pomfret Castle's_ main truck by inches. Presently the Blimp swung round and faced the wind, keeping on a course slightly diverging from that of the convoy. Plugging away dead in the eye of the wind its progress was not more than twenty miles an hour "over the ground", which in reality was a portion of the English Channel.
