"Aviators have to be the ears as well as the eyes in this flood fighting," went on Colonel Wiljohn, "I'm expecting great things of even this dog plane you've brought down, but we've got to get radio equipment installed on it before you take it out on the job. Radio is our time-saver. You can wireless a message in one-twentieth of the time it would take you to zoom back and forth delivering reports by word of mouth. There's an extra seaplane here, already radio-equipped. You can take that out."
