17 June 1986: After being returned to flyable condition, B-47E-25-DT Stratojet serial number 52-166, made the very last flight of a B-47 when it was flown by Major General John D. (“J.D.”) Moore and Lieutenant Colonel Dale E. Wolfe, U.S. Air Force, from the Naval Air Weapons Station China Lake in the high desert of Southern California, to Castle Air Force Base in California’s San Joaquin Valley, to be placed on static display.
52-166 had been built by the Douglas Aircraft Company at Air Force Plant No. 3, Tulsa, Oklahoma, in 1952. 52-166 had not been flown in twenty years, having sat in the Mojave Desert serving as a radar target. General Moore and Colonel Wolf were experienced B-47 pilots, though they hadn’t flown one in the same twenty years. Because the B-47 it had not been through a complete overhaul prior to the ferry flight, it was decided to leave the landing gear extended to avoid any potential problems.
During the 43 minute trip, the aircraft had several systems fail, including airspeed sensors, intercom, and partial aileron control. On approach to Castle Air Force Base, a 16 foot (4.9 meters) approach parachute was deployed. This created enough aerodynamic drag to slow the airplane while the early turbojet engines were kept operating at high power settings. These engines took a long time to accelerate from idle, making a go-around a very tricky maneuver. Releasing the chute allowed the airplane to climb out as the engines were already operating at high r.p.m.

Designed by Boeing, the Stratojet was a high-subsonic speed strategic bomber and reconnaissance aircraft, in service from 1951 until 1977. The B-47 could fly higher and faster than jet fighters of the time, and it was also highly maneuverable. B-47E (Boeing Model 450-157-35) was flown by a two pilots in a tandem cockpit. A navigator/bombardier was at a station in the nose.
The B-47E Stratojet differed from the earlier B-47B primarily with upgraded engines and strengthened landing gear to handle an increase in maximum weight. The B-47E Stratojet is 107.1 feet (32.644 meters) long with a wingspan of 116.0 feet (35.357 meters), and an overall height of 28.0 feet (8.534 meters). The wings are shoulder-mounted and have a total area of 1,428 square feet (132.67 square meters). The wings’ leading edges are swept aft to 36° 37′. The angle of incidence is 2° 45′ and there is 0° dihedral (the wings were very flexible). The B-47E in standard configuration had an empty weight of 78,620 pounds (35,661 kilograms) and maximum takeoff weight of 200,000 pounds (90,718 kilograms).
The B-47E was powered by six General Electric J47-GE-25 turbojet engines in four nacelles mounted on pylons below the wings. This engine has a 12-stage axial-flow compressor, eight combustion chambers, and single-stage turbine. The -25 has a continuous power rating of 5,320 pounds of thrust (23.665 kilonewtons) at 7,630 r.p.m., at Sea Level; Military Power, 5,670 pounds (25.221 kilonewtons) at 7,800 r.p.m. (30 minute limit); and Maximum Power, 7,200 pounds (32.027 kilonewtons) at 7,950 r.p.m. with water/alcohol injection (5 minute limit). The J47-GE-25 has a maximum diameter of 3 feet, 1 inch (0.940 meters) and length of 12 feet, 0 inches (3.658 meters) and weighs 2,653 pounds (1,203 kilograms)
The B-47E had a maximum speed of 497 knots (572 miles per hour/920 kilometers per hour) at 20,000 feet (6,096 meters), and 485 knots (558 miles per hour/898 kilometers per hour) at 38,600 feet (11,765 meters).
The service ceiling was 31,500 feet (9,601 meters) and combat ceiling 40,800 feet (12,436 meters).
The combat radius of the B-47E was 1,780 nautical miles 2,048 miles (3,297 kilometers with a 10,000 pound (4,536 kilograms) bomb load. Ferry range with 14,720 gallons (55,721 liters) of fuel was 4,095 nautical miles (4,712 miles/7,584 kilometers).
For defense the B-47E was armed with two M24A1 20 mm autocannons with 350 rounds of ammunition per gun. The remotely-operated tail turret was controlled by the co-pilot.
The maximum bomb load of the B-47E was 12,000 pounds (5,443 kilograms). The B-47 could carry up to six 2,000 pound (907 kilogram) bombs, or one 10,670 pound (4,840 kilograms) “Special Store”: a B-41 three-stage radiation-implosion thermonuclear bomb with a yield of 25 megatons).

A total of 2,032 B-47s were built by a consortium of aircraft manufacturers: Boeing Airplane Company, Wichita, Kansas; Douglas Aircraft Company, Tulsa, Oklahoma; Lockheed Aircraft Company, Marietta, Georgia.
The Stratojet is one of the most influential aircraft designs of all time and its legacy can be seen in almost every jet airliner built since the 1950s: the swept wing with engines suspended below and ahead on pylons. The B-47 served the United States Air Force from 1951 to 1977. From the first flight of the Boeing XB-47 Stratojet prototype, 17 December 1947, to the final flight of B-47E 52-166, was 38 years, 6 months, 1 day.

Flight Captain Jackie Cochran, R.A.F. Air Transport Auxiliary. (Indian Palms Historical Society)
17–19 June 1941: Jacqueline (“Jackie”) Cochran was the first woman to fly a bomber across the Atlantic Ocean when she ferried a Lockheed Hudson from Canada to Scotland. The airplane was a twin-engine Lockheed Model 414 Hudson Mk.V (LR), Royal Air Force identification AM790 (Lockheed serial number 414-2872).
Recognizing that the War would require all available pilots, the United Kingdom’s Lord Beaverbrook and the United States Army Air Forces Chief of Staff, Major General Henry Harley (“Hap”) Arnold, felt the need to demonstrate that civilian women could serve as pilots of military aircraft in non-combat situations. Jackie Cochran, a famous record-setting pilot, was selected for the assignment.
Cochran had previously served as a Flight Captain ¹ with the Royal Air Force Air Transport Auxiliary. After a period of six months, she had returned to the United States at the request of General Arnold, where she served on his staff.
For this ferry flight, Captain Edgar Grafton Carlisle, Jr.,² was assigned as her navigator. The Hudson also carried a radio operator, today only remembered as Coates. Royal Canadian Air Force authorities felt that Miss Cochran was not physically strong enough to operate the Hudson’s hand brakes. The arrangement between her and the R.C.A.F. was that she would be allowed to fly the bomber as First Officer, but that Captain Carlisle would make all takeoffs and landings.³
Cochran, Carlisle and Coates departed Montréal, Québec, at 1920 G.M.T., 17 June, en route to Gander, Newfoundland. They flew 931 statute miles (1498 kilometers) in 5 hours, 4 minutes before landing at 0024 G.M.T., 18 June, and remained there overnight.

The following evening, 18 June, at 1857 G.M.T., they took off to fly across the North Atlantic Ocean, a distance of 2,122 statute miles (3,415 kilometers).

In her autobiography, Cochran wrote:
Flying the ocean at night didn’t mean much. We were above an overcast and hardly saw water. But just before daylight, we were heard or spotted by radar and suddenly through the darkness tracer bullets came up in front and around us. There was sudden consternation on board. Carlisle rushed up to me and the radio operator came running out of his compartment with his Very pistol. He opened a hatch and by firing a certain colored bullet gave the signal of the day but this really served no purpose because the light could not have been seen from the surface of the water anyway and the firing at us was probably coming from a German submarine or one of our own friendly ships. I thought maybe the pilots in the mass meeting in Montreal were right after all and the Germans were going to make a test case of me. Anyway, the tracer bullets stopped almost as soon as they started and no noticeable damage was done to the plane. After daylight, a hole opened up in the overcast and we saw a ship burning at sea, but could do nothing about it except to make a report by radio because we had no fuel to spare to enable us to go down and cruise around. Then we caught sight of the coast of Ireland in the distance and it kept creeping up on us and growing larger and larger and more friendly. From off the coast of Ireland to Prestwick, Scotland, was a tortuous air route. The route went one way and then another—without any real pattern—and the route was changed daily to make it difficult for enemy planes or submarines to intercept. At the end of twelve hours, we came to a stop on the runway. Carlisle, under the regulation, made the landing.

Jackie Cochran would go on to form the Women Airforce Service Pilots (WASPs).
The image below shows the Hudson ferried by Jackie Cochran in service later in the War. It is painted in the Coastal Command camouflage scheme.
The Lockheed Hudson was a twin engine light bomber developed by Lockheed from its Model 14 Super Electra civil transport. Both types were designed by the legendary Clarence L. (“Kelly”) Johnson. The B-14L prototype made its first flight 10 December 1938 from the Union Air Terminal at Burbank, California. It was flown by two Royal Air Force officers, Squadron Leader James Addams and Squadron Leader Randle. The prototype (also identified as Model 214-40-01) was purchased by Great Britain and assigned the R.A.F. identification N7205.
The Hudson flown by Cochran, AM790, was an improved Model 414, Hudson Mk.V. This was identical to the earlier Mk.III, with the substitution of Pratt & Whitney R-1830-S3C4-G Twin Wasp engines. The bomber was flown by a single pilot, with a navigator/bombardier, radio operator and gunner.
The Hudson Mk.V was 44 feet 3⅞ inches (13.513 meters) long with a wingspan of 65 feet, 6 inches (19.964 meters) and height of 11 feet, 10 inches (3.607 meters). It had a maximum gross weight of 20,000 pounds (9,072 kilograms).
The Mk.V was equipped with two air-cooled, supercharged 1,829.4-cubic-inch-displacement (29.978 liter) Pratt & Whitney Twin Wasp S3C4-G (R-1830-61) two-row fourteen-cylinder radial engines with a compression ratio of 6.7:1. These had a normal power rating of 1,100 horsepower at 2,550 r.p.m. to 6,200 feet (1,890 meters) and 1,000 horsepower at 2,550 r.p.m at 12,500 feet (3,810 meters). The takeoff/military power rating was 1,200 horsepower at 2,700 r.p.m. to 4,900 feet (1,494 meters) and 1,050 horsepower at 13,100 feet (3,993 meters). The engines turned three-bladed propellers though a 16:9 gear reduction. They were 5 feet, 3.48 inches (1.612 meters) long, 4 feet, 0.19 inches (1.224 meters) in diameter, and weighed 1,495 pounds (678 kilograms).
The Hudson had a cruise speed of 220 miles per hour (354 kilometers per hour, and maximum speed of 246 miles per hour (396 kilometers per hour) at 6,500 feet (1,981 meters). Its service ceiling was 25,000 feet (7,620 meters).
The Hudson was designed to carry four 250 pound (113 kologram) or six 100 pound (45 kilogram) bombs. It was armed with two forward-firing .303 Browning Machine Gun Mk.II mounted in the nose and operated by the pilot, with another two .303s on flexible mounts at the waist position, and 2 additional Mk.IIs in a power-operated Bolton Paul dorsal turret. Eight rockets could be carried under the wings.
409 Hudson Mark Vs were built. 207 of these were a long range variant, the Hudson Mk.V(LR).
During World War II, Hudson Mk.V(LR) AM790 served with No. 500 and No. 608 Squadrons, both units of the Coastal Command, Royal Air Force.
¹ An ATA Flight Captain was an equivalent rank to a Royal Air Force Squadron Leader.
² Edgar Grafton Carlisle, Jr., was born 17 October 1908, at Baltimore, Maryland, and was a citizen of the United States. He was the first of six children of Edgar Grafton Carlisle and Elizabeth Henderson Spafford Carlisle. A former resident of Swarthmore, Pennsylvania, Carlisle was a 1928 graduate of the University of Pennsylvania.
He entered the United States Army as an aviation cadet at Kelly Field, Bexar, Texas, earning his reserve officer’s commission and aviator’s wings in 1930. He served as a lieutenant in the 28th Division Aviation Unit, Pennsylvania National Guard and commanded the 103rd Photo Section.
Carlisle married the former Miss Lillian Matarose Baker at Narberth, Pennslyvania, 9 January 1933. They would have two children.
Carlisle entered the Royal Air Force Ferry Command in September 1940. To do so, he was required to resign his reserve commission in the United States Army. In the King’s New Year’s Honors List, 1 January 1942, Captain Edgar Grafton Carlisle, R.A.F.F.C., was invested an Officer of the Most Excellent Order of the British Empire (Honorary). The insignia of this honor was presented at Government House, 3 February 1942, by Lord Athlone, Governor General of the Dominion of Canada.
Following the War, Carlisle worked in the banking industry. He also taught Aerial Navigation at the University of Vermont.
Edgar Grafton Carlisle, Jr., O.B.E., died at Burlington, Vermont, 27 March 1994.

17 June 1937: Leg 19. “From Karachi on June 17 we flew 1,390 miles to Calcutta, landing at Dum Dum airdrome shortly after four in the afternoon. Low clouds hung about during the beginning of the flight, but these disappeared as we drew near the Sind Desert. Through this great barren stretch rough ridges extended almost at right angles to our course. A southerly wind whipped the sand into the air until the ground disappeared from view in regular ‘dust bowl’ fashion. We flew along until the ridges grew into mountains and poked their dark backs like sharks through a yellow sea. these acted as a barrier to the sand, and the air cleared somewhat, so we could again see what we were flying over – dry river beds, a few roads connecting villages, and then a railroad.” —Amelia Earhart

Fokker F.VIIb/3m Friendship on Southampton Water, after the transatlantic flight.
17–18 June 1928: Amelia Mary Earhart became the first woman to cross the Atlantic Ocean by air when she accompanied pilot Wilmer Lower Stultz and mechanic Louis Edward Gordon as a passenger aboard the Fokker F.VIIb/3m, NX4204, Friendship. The orange and gold, float-equipped, three-engine monoplane had departed from Trepassey Harbor, Newfoundland and Labrador, Canada, and arrived at Burry Port, on the southwest coast of Wales, 20 hours, 40 minutes later.
Amelia Earhart wrote 20 hrs. 40 min.—Our Flight in the Friendship (G.P. Putnam’s Sons, New York, 1928), describing her adventure.
Friendship had been originally ordered by Richard E. Byrd for his Antarctic expedition, but because Ford Motor Company was a major sponsor, he made the decision to switch to a Ford Tri-Motor airplane. Byrd sold the new Fokker to Donald Woodward, heir to the Jell-O Corporation, for $62,000, and it was registered to his Mechanical Science Corp., of Le Roy, New York. Woodward then leased the airplane to Mrs. Frederick Edward Guest (née Anne T. Phipps, also known as Amy Phipps) for her to cross the Atlantic Ocean by air. She chose the name Friendship for the airplane.
Amy Phipps Guest
Mrs. Guest was a daughter of Henry Phipps, Jr., an American industrialist. She was married to Captain the Right Honourable Frederick Edward Guest P.C., C.B.E., D.S.O., M.P., a prominent British politician, former Secretary of State for Air, and a member of His Majesty’s Most Honourable Privy Council. Amy Phipps Guest, however, was a multi-billionaire in her own right.
Mrs. Guest was not a pilot, so Stultz and Gordon had been hired to fly the airplane. When her family ruled out her transoceanic journey, “an American girl of the right type” was selected to make the flight in her place. Miss Amelia Mary Earhart, a social worker living in Boston, was interviewed and was the candidate selected.
Although Earhart was a pilot with approximately 500 hours of flight experience, she did not act as a pilot on this flight. She was, however, the aircraft commander. Instructions from Mrs. Guest’s attorney, David T. Layman, to Stultz and Gordon, dated 18 May 1928, were very specific on this matter:
“This is to say that on arrival at Trepassey of the tri-motor Fokker plane “FRIENDSHIP” if any questions of policy, procedure, personnel or any other question arises the decision of Miss Amelia M. Earhart is to be final. That she is to have control of the plane and of the disposal of the services of all employees as fully as if she were the owner. And further, that on arrival of the plane in London full control of the disposition of the plane and of the time and services of employees shall be hers to the same extent until and unless the owner directs otherwise.”

It was during the planning for this flight that Earhart first met her future husband, George Palmer Putnam.
Though Friendship was equipped with aluminum pontoons for water takeoffs and landings, it was otherwise the same type as Southern Cross, the airplane that Sir Charles E. Kingsford Smith flew from the United States to Australia earlier in the month. It was built by Anton H.G. Fokker’s N. V.Nederlandsche Vliegtuigenfabriek at Veere, Netherlands, in early 1928. Friendship , serial number 5028, was the fourth aircraft in the series. Flown by Bernt Balchen, it made its first flight 16 February 1928.
The Fokker F.VIIb/3m is a three-engine high-wing passenger transport with fixed landing gear. It could carry up to 8 passengers. The airplane was 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).

Stultz, and Mrs. Lucia Marian Foster Welch, Mayor of the City of Southampton. (Purdue University Libraries, Karnes Archives and Special Collections via the BBC)
The F.VIIb/3m was powered by three 787.26-cubic-inch-displacement (12.90 liter) air-cooled Wright Aeronautical Corporation Model J-5C Whirlwind nine-cylinder radial engines. The left engine was serial number 8229, the center, 8280, and the right engine, 8321. These were direct-drive engine with a compression ratio of 5.1:1. The J-5C was rated at 200 horsepower at 1,800 r.p.m., and 220 horsepower at 2,000 r.p.m. They drove two-bladed Standard adjustable-pitch propellers. The Wright J-5C 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).
The standard 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). NX4204 was modified at Fokker’s American subsidiary, Atlantic Aircraft Corporation in Teterboro, New Jersey, increasing the total fuel capacity to 870 gallons (3,293 liters).

Friendship was sold to José Roger Balet of Argentina in May 1929, and renamed 12 de Octubre, the date of an important national holiday. On 21 June 1931, the airplane was on a commercial flight from Santiago de Chile to Mendoza when it made an emergency landing in Alto Sierra. It was acquired by General Enrique Bravo for the Fuerza Aérea Nacional, November 1931.
