at Wake Island on May 9, 1935, with construction workers and the necessary materials and equipment to start to build Pan American facilities and to clear the lagoon for a flying boat landing area. The atoll's encircling coral reef prevented the ship from entering and anchoring in the shallow lagoon itself. The only suitable location for ferrying supplies and workers ashore was at nearby Wilkes Island; however, the chief engineer of the expedition, Charles R. Russell, determined that Wilkes was too low and at times flooded and that Peale Island was the best site for the Pan American facilities. To offload the ship, cargo was lightered (barged) from ship to shore, carried across Wilkes and then transferred to another barge and towed across the lagoon to Peale Island. By inspiration, someone had earlier loaded railroad track rails onto North Haven, so the men built a narrow-gauge railway to make it easier to haul the supplies across Wilkes to the lagoon. The line used a flatbed car pulled by a tractor. On June 12, North Haven departed for Guam, leaving behind various PAA technicians and a construction crew. Out in the middle of the lagoon, Bill Mullahey, a swimmer from Columbia University, was tasked with blasting hundreds of coral heads from a long, wide, deep landing area for the flying boats. In total some of dynamite were used on the coral heads in the Wake Atoll lagoon. On August 17, the first aircraft landing at Wake Island occurred when a PAA flying boat, on a survey flight of the route between Midway and Wake, landed in the lagoon. The second expedition of North Haven arrived at Wake Island on February 5, 1936, to complete the construction of the PAA facilities. A five-ton diesel locomotive for the Wilkes Island Railroad was offloaded and the railway track was extended to run from dock to dock. Across the lagoon on Peale workers assembled the Pan American Hotel, a prefabricated structure with 48 rooms and wide porches and verandas. The hotel consisted of two wings built out from a central lobby with each room having a bathroom with a hot-water shower. The PAA facilities staff included a group of Chamorro men from Guam who were employed as kitchen helpers, hotel service attendants and laborers. The village on Peale was nicknamed "PAAville" and was the first "permanent" human settlement on Wake. By October 1936, Pan American
