By 1940, Wheeler Field had evolved into a primary base for Army Air Corps pursuit (i.e., "fighter") aircraft such as the P-40
Amelia Earhart theory. Billings claims that the serial numbers written on the map, , represent: These would be consistent with a Lockheed Electra 10E, such as that flown by Earhart, although they do not contain enough information to identify the wreck in question as NR16020. Pacific Wrecks, a website that documents World War II-era aircraft crash sites, notes that no Electra has been reported lost in or around Papua New Guinea. Gillespie wrote that the distance from Earhart's last known position to New Britain was impossible for the aircraft to fly, requiring more than 13 hours of flight when there were only
