 Eventually, the runway for fighter aircraft was built on Middleburg Island and for bombers near Mar to the northeast (the landing strip is still visible to this day), although the control of Sausapor was vital for the security of the base to launch the campaign and remained an air warning radar station.Ships patrolled this area of the coastline throughout the month-long campaign, keeping the Japanese at bay.Operation Globetrotter ended on 31 August and General Douglas MacArthur's last point of landing on the way back to the Philippines was at Sansapor.
