18 March 1937, 5:40 a.m.: Amelia Earhart and her crew sighted Diamond Head on the island of Oahu, Hawaiian Islands. The Electra landed at Wheeler Army Airfield, Honolulu, after an overnight flight from Oakland, California, completing the first leg of a planned around-the-world flight in 15 hours, 47 minutes.
The airplane was Earhart’s Lockheed Electra 10E Special, registration NR16020. Also aboard were Paul Mantz, Amelia’s friend and adviser, as co-pilot, navigator Captain Frederick Joseph Noonan, formerly of Pan American Airways, and Captain Harry Manning of United States Lines, also a close friend of Amelia’s, acting as radio operator and navigator.
About an hour after takeoff from Oakland, California, the Electra overtook the Pan American Airways Hawaii Clipper, which had departed San Francisco Bay an hour-and-a-half before Earhart. She took photographs of the Martin M-130 flying boat.
In her log, Amelia Earhart described the sunset over the Pacific Ocean:
“. . . golden edged clouds ahead, then the golden nothingness of sunset beyond. . . The aft cabin is lighted with a weird green blue light, Our instruments show pink. The sky rose yellow. . . Night has come. The sea is lovely. Venus is setting ahead to the right. The moon is a life-saver. It gives us a horizon to fly by. . . .”
— Amelia: The Centennial Biography of an Aviation Pioneer, by Donald M. Goldstein and Katherine V. Dillon, Brassey’s, Washington and London, 1997, Chapter 18 at Page 171.
On arrival at Hawaii, Earhart, saying that she was very tired, asked Paul Mantz to make the landing at Wheeler Field.
22 November 1935: The Pan American Airways flying boat, China Clipper, a Martin M-130, NC14716, departed Alameda, California (an island in San Francisco Bay) at 3:46 p.m., Friday, and arrived at Honolulu at 10:39 a.m., Saturday, completing the first leg of a five-day trans-Pacific flight to Manila in the Philippine Islands.
The aircraft commander was Captain Edwin Charles Musick, with First Officer Robert Oliver Daniel (“Rod”) Sullivan. The navigator was Frederick Joseph Noonan, who would later accompany Amelia Earhart on her around-the-world flight attempt. There were also a Second Officer and two Flight Engineers. The cargo consisted of 110,000 pieces of U.S. Mail.
Pan Am personnel called the Clipper “Sweet Sixteen,” referring to its Civil Aeronautics Board registration number, NC14716. The airplane and Humphrey Bogart starred in a 1936 First National Pictures movie, “China Clipper.”
NC14716 was the first of three Martin M-130 four-engine flying boats built for Pan American Airways and was used to inaugurate the first commercial transpacific air service from San Francisco to Manila in November, 1935. Built at a cost of $417,000 by the Glenn L. Martin Company in Baltimore, Maryland, it was delivered to Pan Am on October 9, 1935. The airplane’s serial number was 558.
The M-130 was operated by a flight crew of 6–9, depending on the length of the flight, plus cabin staff, and could carry 18 passengers on overnight flights, or a maximum 36 passengers.
The Martin M-130 was 90 feet, 10.5 inches (27.699 meters) long with a wingspan of 130 feet, 0 inches (39.624 meters). It was 24 feet, 7 inches (7.493 meters) high. The total wing area was 2,315 square feet (215 square meters), including the “sea wings”. Its maximum takeoff weight was 52,252 pounds (23,701 kilograms).
The flying boat was powered by four air-cooled, supercharged Pratt & Whitney Twin Wasp S2A5-G two-row 14-cylinder radial engines with a compression ratio of 6.7:1. They had a normal power rating 830 horsepower at 2,400 r.p.m., and 950 horsepower at 2,550 r.p.m. for takeoff. They drove three-bladed Hamilton Standard Hydromatic constant-speed propellers through a 3:2 gear reduction. The S2A5-G was 3 feet, 11.88 inches (1.216 meters) in diameter, 4 feet, 8.75 inches (1.441 meters) long, and weighed 1,235 pounds (560 kilograms).
The airplane had a cruise speed of 130 miles per hour (209 kilometers per hour) and a maximum speed of 180 miles per hour (290 kilometers per hour). The M-130’s service ceiling was 10,000 feet (3,048 meters). Its range was 3,200 miles (5,150 kilometers).
2 July 1937: At approximately 10:00 a.m., local time, Amelia Earhart and Fred Noonan departed Lae, Territory of New Guinea, aboard their Lockheed Electra 10E Special, NR16020, enroute to Howland Island, 2,243 nautical miles (2,581 statute miles/4,154 kilometers) east-northeast across the South Pacific Ocean. The airplane was loaded with 1,100 gallons (4,164 liters) of gasoline, sufficient for 24 to 27 hours of flight.
1 July 1937: Amelia Earhart and Fred Noonan are delayed another day at Lae, Territory of New Guniea.
“July 1st. ‘Denmark’s a prison,’ and Lae, attractive and unusual as it is, appears to two flyers just as confining, as the Electra is poised for our longest hop, the 2,556 miles to Howland Island in mid-Pacific. The monoplane is weighted with gasoline and oil to capacity. However, a wind blowing the wrong way and threatening clouds conspired to keep her on the ground today. In addition, Fred Noonan has been unable, because of radio difficulties, to set his chronometers. Any lack of knowledge of their fastness and slowness would defeat the accuracy of celestial navigation. Howland is such a small spot in the Pacific that every aid to locating it must be available. Fred and I have worked very hard in the last two days repacking the plane and eliminating everything unessential. We have even discarded as much personal property as we can decently get along without and henceforth propose to travel lighter than ever before. All Fred has is a small tin case which he picked up in Africa. I noted it still rattles, so it cannot be packed very full. Despite our restlessness and disappointment in not getting off this morning, we still retained enough enthusiasm to do some tame exploring of the near-by country.” —Amelia Earhart
30 June 1937. Amelia Earhart and Fred Noonan are delayed at Lae, Territory of New Guinea.
“Everyone has been as helpful and co-operative as possible—food, hot baths, mechanical service, radio and weather reports, advice from veteran pilots here—all combine to make us wish we could stay. However, tomorrow we should be rolling down the runway, bound for points east. Whether everything to be done can be done within this time remains to be seen. If not, we cannot be home by the Fourth of July as we had hoped, even though we are one day up on the calendar of California. It is Wednesday here, but Tuesday there. On this next hop we cross the 180th Meridian, the international dateline when clocks turn back twenty-four hours.” —Amelia Earhart
