TO power for as long as limited, then METO power at best rate to optimun, probably about 4000 ft. Then LRC. About 900 gallons to Howland. They had calculated they would have an hours fuel remaining on arrival Howland area. Cant see why Noonan with his experience could have not calculated there westing. Accurate time is required for longitude (delayed departure a day for accurate time check) and she to broadcast " must be on you" or words to that effect . I cant explain the aircraft in the bush in ENB but mistakes can be made. People can be dishonest and cruel. Apparently transmissions received, later established a hoax, pleading they are floating. This was equivalent to putting a man on the moon for the era with the publicity generated by her husband and his political pull.
It would be great to find this mystery aircraft and settle a great mystery
