Delgetti and Bullitt watch the Rome gate at San Francisco International Airport. However, Ross (using Renick's passport) has switched his ticket at the last moment to an earlier London flight. Bullitt boards the plane after it is ordered to return to the terminal, but the mobster escapes through the rear cabin door. A foot chase ensues across the runways. In the crowded passenger terminal, Ross shoots a deputy sheriff before being shot dead by Bullitt. Chalmers arrives to survey the scene, but leaves saying nothing. Bullitt returns home early on Monday morning to find Cathy asleep in their bed.
