These include such comments as 'liberated from an airship which was forced to descend at sea. This was the first intimation of the ship being in distress'; 'Returned with message that seaplane was down and totally disabled 45 miles from base. As a result the crew and machine were brought back safely in tow'; 'Seaplane crashed about 10 miles from base, and this bird, although almost drowned, returned with message in time for assistance to be sent....'
