With their speed and maneuverability, the mission demonstrated the "PTs" suitability for search and rescue operations, their greatest strength throughout the war. Around 3:00 a.m. on 2 November, "PT-59" ran out of gas about halfway back to Lambu Lambu and had to be towed by "PT-236". Both "PT"s were vulnerable to Japanese airstrikes during the slow towing process, and Kennedy called for air support. To Kennedy's dismay, all of the 4-6 Australian P-40's that responded to provide cover were eventually shot down.
