9 June 1928: At 10:50 a.m., Charles Edward Kingsford Smith, M.C., and his crew completed the first trans-Pacific flight from the mainland United States of America to the Commonwealth of Australia. They landed their airplane, a Fokker F.VIIb/3m named Southern Cross, ¹ at Brisbane, Queensland, Australia. The airplane’s crew were Kingsford Smith, pilot; Charles Ulm, co-pilot; Harry Lyon, navigator; and James Warren, radio operator. Their historic flight had begun at Oakland, California, on 31 May.

The first leg of the flight from Oakland Field, California, to Wheeler Field was 2,406 miles (3,873 kilometers). The elapsed time was 27 hours, 27 minutes. After resting in Hawaii, the crew took off on the second leg to Suva, Fiji, a distance of 3,167 miles (5,097 kilometers). Southern Cross landed at Albert Park. It was the very first airplane to land in Fiji. This was the longest leg and took 34 hours, 33 minutes. The final leg to Brisbane covered 1,733 miles (2,788 kilometers) and took 21 hours, 35 minutes. They landed at Eagle Farm Airport, just northeast of Brisbane, at 10:50 a.m., 9 June 1928. An estimated 25,000 people were there to see the arrival.

The Fokker F.VIIb/3m was designed and built as a commercial airliner. It was heavier and had a larger wing than the F.VIIa/3m. It was 14.6 meters (47.9 feet) long, with a wingspan of 21.7 meters (71.2 feet) and 3.9 meters (12.8 feet) high. The wing had an area of 67 square meters (721 square feet). Its empty weight was 3,050 kilograms (6,724 pounds) and the gross weight, 5,200 kilograms (11,464 pounds).

The F.VIIb/3m had a cruise speed of cruise 170 kilometers per hour (106 miles per hour), and maximum speed of 190 kilometers per hour (118 miles per hour). Its service ceiling was 4,750 meters (15,584 feet). It had a normal range of 1,240 kilometers (771 miles).

Southern Cross had been built by N.V. Koninklijke Nederlandse Vliegtuigenfabriek Fokker at Amsterdam, Netherlands, for Hubert Wilkins who intended to use it for Arctic exploration. It was the first long-wing F.VII, c/n 4954, which would later be referred to as the F.VIIb. The airplane was crated and shipped to the United States, where it was reassembled by Atlantic Aircraft Corporation, Fokker’s American subsidiary in Teterboro, New Jersey. Wilkins’ expedition was sponsored by the Detroit News newspaper, and he named the new airplane Detroiter.

The airplane was damaged in a hard landing, and together with Wilkins’ single-engine F.VII, Alaskan, shipped to Boeing in Seattle, Washington, for repair. It is commonly believed that the two airplanes were used together to produce the rebuilt Southern Cross. While repairs were ongoing, Wilkins sold the Fokker to Kingsford Smith for $3,000. Kingsford Smith had the original Wright J-4 engines replaced with J-5 Whirlwinds, and the fuel capacity increased to 1,267 gallons (4,872 liters).

Southern Cross was powered by three air-cooled, normally-aspirated 787.26-cubic-inch-displacement (12.901 liter) Wright Aeronautical Corporation Model J-5 Whirlwind 9-cylinder radial engines. These were direct-drive engines with a compression ratio of 5.1:1. The J-5 was rated at 200 horsepower at 1,800 r.p.m., and 220 horsepower at 2,000 r.p.m. The engine was 2 feet, 10 inches (0.864 meters) long and 3 feet, 9 inches (1.143 meters) in diameter. It weighed 508 pounds (230.4 kilograms).

Southern Cross was registered to Charles E. Kingsford Smith, et al., 18 October 1927, by the United States Department of Commerce Aeronautics Branch. It was assigned the registration mark NC1985. (The registration was cancelled 20 March 1930.)

The expense of completing the repairs to the airplane took most of Kingsford Smith’s money, so he sold the airplane to George Allan Hancock, owner of Rancho La Brea Oil Company—think, “La Brea Tar Pits”—the developer of the Hancock Park section of Los Angeles, and founder of Santa Maria Airport in Santa Barbara County, California. Hancock loaned Southern Cross back to Kingsford Smith for the Trans-Pacific flight.

An estimated 25,000 people were waiting at Eagle Farm for Southern Cross’ arrival. (Sydney Morning Herald)

Following its arrival in Australia, the Fokker was re-registered G-AUSU. When Australia began issuing its own aircraft registrations, this was changed to VH-USU.

After several other historic flights, Kingsford Smith donated Southern Cross to the government of Australia to be placed in a museum. It was stored for many years but is now on display at the Kingsford Smith Memorial at Brisbane Airport. ²

Kingsford Smith, formerly a captain with the Royal Air Force, was given the rank of Air Commodore, Royal Australian Air Force, and awarded the Air Force Cross. He was invested Knight Bachelor in 1932. Sir Charles continued his adventurous flights.

On 8 November 1935, while flying Lady Southern Cross, a Lockheed Altair, from Allahabad, India, to Singapore, Air Commodore Sir Charles Edward Kingsford Smith, A.F.C., M.C., and his co-pilot, Tommy Pethybridge, disappeared over the Andaman Sea.

Crux, the Southern Cross.

¹ Southern Cross refers to the constellation Crux, one of the most easily recognizable constellations in the southern hemisphere. The constellation is seen on the national flags of Australia, Brazil, New Zealand, Papua New Guinea and Samoa.

² At the time of the Pacific crossing, the fuselage of Southern Cross was painted a light blue color, reportedly the same shade being used on U.S. Army Air Corps training aircraft at the time. It was later repainted in a darker blue, similar to the flag of Australia.

8 June 1966: During a publicity photo formation flight, a Lockheed F-104N Starfighter, N813NA, flown by NASA Chief Research Test Pilot Joseph A. Walker, was caught in the wingtip vortices of the North American Aviation XB-70A-2 Valkyrie, 62-0207, the second prototype Mach 3+ strategic bomber. The Starfighter rolled up and across the Valkyrie. The two airplanes collided, with the F-104 taking off the Valkyrie’s vertical fins, then exploding.

The Valkyrie continued to fly straight and level for 16 seconds before it began to roll inverted. The B-70’s pilot, Alvin S. White, was able to eject, though he was severely injured. Joe Walker and B-70 co-pilot Major Carl S. Cross, United States Air Force, were killed.

Still photographs and motion picture film of the formation were being taken from Clay Lacy’s Gates Lear Jet. The photos were for a General Electric publicity campaign showing U.S. military aircraft that were powered by GE engines. Air Force procedures for requesting and approval of publicity flights were not properly followed and it is likely this flight would not have been approved had they been.

Reportedly, just prior to the collision, Walker radioed, “I’m opposing this mission. It is too turbulent and it has no scientific value.”

Scott Crossfield prepares for a flight in the North American Aviation X-15A.

8 June 1959: At Edwards Air Force Base, California, North American Aviation’s Chief Engineering Test Pilot, A. Scott Crossfield, made the first flight of the X-15A hypersonic research rocketplane.

56-6670 was the first of three X-15s built for the U.S. Air Force and NASA. It was airdropped from a Boeing NB-52A Stratofortress, 52-003, at 37,550 feet (11,445 meters) over Rosamond Dry Lake at 08:38:40 a.m, Pacific Daylight Time.

This was an unpowered glide flight to check the flying characteristics and aircraft systems, so there were no propellants or oxidizers aboard, other than hydrogen peroxide which powered the pumps and generators.

The aircraft reached 0.79 Mach (522 miles per hour, 840 kilometers per hour) during the 4 minute, 56.6 second flight.

In his autobiography, Scott Crossfield described the first flight:

“Three” . . . “Two” . . . “One” . . .

“DROP”

Inside the streamlined pylon, a hydraulic ram disengaged the three heavy shackles from the upper fuselage of the X-15. They were so arranged that all released simultaneously, and if one failed they all failed. The impact of the release was clearly audible in the X-15 cockpit. I heard a loud “kerchunk.”

The X-15 hung in its familiar place beneath the pylon for a split second. Then the nose dipped sharply down and to the right more rapidly than I had anticipated. The B-52, so long my constant companion, was gone. The X-15 and I were alone in the air and flying 500 miles an hour. In less than five minutes I would be on the ground. . . .

There was much to do in the first hundred seconds of flight. First I had to get the “feel” of the airplane, to make certain it was trimmed out for landing just as any pilot trims an airplane after take-off or . . . when dwindling fuel shifts the center of gravity. Then I had to pull the nose up, with and without flaps, to feel out the stall characteristics, so that I would know how she might behave at touchdown speeds . . . My altimeter unwound dizzily: from 24,000 to 13,000 feet in less than forty seconds. . . .

X-15A 56-6670 drops from the wing of the B-52 mothership. This is a glide flight as there is no frost from cryogenic propellants showing of the fuselage. The vapor trail is from hydrogen peroxide that powers the aircraft power systems. Note the roll to the right as the X-15 drops from the pylon. (NASA)

The desert was coming up fast. At 600 feet altitude I flared out. . . .

In the next second without warning the nose of the X-15 pitched up sharply. It was a maneuver that had not been predicted by the computers, an uncharted area which the X-15 was designed to explore. I was frankly caught off guard. Quickly I applied corrective elevator control.

The nose went down sharply. But instead of leveling out, it tucked down. I applied reverse control. The nose came up but much too far. Now the nose was rising and falling like a skiff in a heavy sea. Although I was putting in maximum control I could not subdue the motions. The X-15 was porpoising wildly, sinking toward the desert at 200 miles an hour. I would have to land at the bottom of an oscillation, timed perfectly; otherwise, I knew, I would break the bird. I lowered the flaps and the gear. . . .

. . . With the next dip I had one last chance and flared again to ease the descent. At that moment the rear skids caught on the desert floor and the nose slammed over, cushioned by the nose wheel. The X-15 skidded 5,000 feet across the lake, throwing up an enormous rooster tail of dust. . . .

Before the drop, it was discovered that the aircraft’s Stability Augmentation System was inoperative in pitch mode. During the flight it was found that the hydraulic-assisted flight control system was responding too slowly to Crossfield’s inputs. Engineers analyzed the problem and increased the hydraulic system pressure. The problem never recurred.

Scott Crossfield was the world’s most experienced rocketplane pilot with 82 rocketplane flights before the X-15 program. “. . . he was intimately involved in the design of the aircraft and contributed immensely to the success of the design.”

North American Aviation X-15A 56-6670 made the first glide flight and the first and last powered flights of the X-15 Program. It made a total of 82 of the 199 X-15 flights. 56-6670 is in the collection of National Air and Space Museum at Washington, D.C.

Reception for Amelia Earhart and Fred Noonan at Dakar, French West Africa. (Purdue University Libraries, Archives and Special Collections)

8 June 1937: Leg 11. After landing at Saint-Louis, French West Africa, the previous evening, Amelia Earhart and Fred Noonan reposition the Lockheed Electra 10E, NR16020, to Dakar, their intended destination. They lay over until 10 June for rest and maintenance on the airplane.

“On the morning of June 8 we flew the 163 miles from St. Louis. The chief reason I decided to lay over a day at Dakar instead of proceeding east was because my fuelmeter gave out two hours after we left Natal. The very efficient chief mechanic at Dakar discovered that a piece of the shaft was broken. While he worked on that – a difficult job to manage from a blueprint printed in English, which he did not understand, in an aeroplane he did not know – I had a forty-hour check of the engines, probably all they would need until we reached Karachi.”
