The Last Peacemaker: This gigantic airplane, a Convair B-36J-75-CF Peacemaker, serial number 52-2827, was the very last of the ten-engine strategic bombers built by the Convair Division of General Dynamics at Fort Worth, Texas. It was completed 1 July 1954. On 14 August, it was delivered to the Strategic Air Command, 92nd Bombardment Wing, Heavy, at Fairchild Air Force Base, Washington. In April 1957, 52-2827 was assigned to the 95th Bombardment Wing, Heavy, at Biggs Air Force Base, El Paso, Texas.

The last one built, 52-2827 was also the last operational B-36.

On 12 February 1959, after 4 years, 5 months, 30 days service, the Air Force returned the bomber to Fort Worth. 52-2827 departed Biggs Air Force Base at 11:00 a.m., under the command of Major Frederick J. Winter. Other pilots were Colonel Gerald M. Robinson, commanding the 95th Wing, and Captain Wilson P. Smith. (Colonel Robinson flew as first pilot during the takeoff, while Major Winter flew the landing.) The bomber’s crew were hand-picked, and included two navigators, two flight engineers, an observer, two radio operators, two gunners and a crew chief. Ten newspaper, radio and television reporters were on board as well.

The B-36 touched down at Amon Carter Field at 2:55 p.m. The Peacemaker’s log book was closed out with a total of 1,414 hours, 50 minutes, flight time.

After a ceremony attended by thousands, the bomber was officially retired. A bugler blew “Taps,” and then the Peacemaker was towed away.

It was put on display at Amon Carter Field. After decades of neglect, the bomber was placed in the care of the Pima Air and Space Museum at Tucson for restoration and display.

Convair B-36J 52-2827 is one of 14 “Featherweight III” high altitude variants. It was built without the six retractable defensive gun turrets of the standard B-36, retaining only the two M24A1 20 mm autocannons in the tail. This reduced the crew requirement to 13. It is 162 feet, 1 inch (49.403 meters) long with a wingspan of 230 feet (70.104 meters) and overall height of 46 feet, 9 inches (14.249 meters). The empty weight is 166,125 pounds (75,353 kilograms) and loaded weight is 262,500 pounds (119,068 kilograms). Maximum takeoff weight is 410,000 pounds (185,973 kilograms).

The B-36J has ten engines. There are six air-cooled, supercharged 4,362.49 cubic-inch-displacement (71.488 liter) Pratt & Whitney Wasp Major C6 (R-4360-53) four-row, 28-cylinder radial engines placed inside the wings in a pusher configuration. These had a compression ratio of 6.7:1 and required 115/145 aviation gasoline. The R-4360-53 had a Normal Power rating of 2,800 horsepower at 2,600 r.p.m. Its Military Power rating was 3,500 horsepower at 2,800 r.p.m., and 3,800 horsepower at 2,800 r.p.m. with water injection—the same for Takeoff. The engines turned three-bladed Curtiss Electric constant-speed, reversible propellers with a diameter of 19 feet, 0 inches (5.791 meters) through a 0.375:1 gear reduction. The R-4360-53 is 9 feet, 9.00 inches (2.972 meters) long, 4 feet, 7.00 inches (1.397 meters) in diameter, and weighs 4,040 pounds (1,832.5 kilograms).

Four General Electric J47-GE-19 turbojet engines are suspended under the wings in two-engine pods. The J47 is a  single-shaft axial-flow turbojet engine with a 12-stage compressor section, 8 combustion chambers, and single-stage turbine. The J47-GE-19 was modified to run on gasoline and was rated at 5,200 pounds of thrust (23.131 kilonewtons).

The B-36J Featherweight III had a cruise speed of 230 miles per hour (370 kilometers per hour) and a maximum speed of 418 miles per hour (673 kilometers per hour). The service ceiling was 43,600 feet (13,289 meters) and its combat radius was 3,985 miles (6,413 kilometers). The maximum range was 10,000 miles (16,093 kilometers).

The B-36 was designed during World War II and nuclear weapons were unknown to the Consolidated-Vultee Aircraft Corporation engineers. The bomber was built to carry up to 86,000 pounds (39,009 kilograms) of conventional bombs in the four-section bomb bay. It could carry the 43,600 pound (19,777 kilogram) T-12 Cloudmaker, a conventional explosive earth-penetrating bomb. When armed with nuclear weapons, the B-36 could carry several Mk.15 3.8 megaton thermonuclear bombs. By combining the bomb bays, one Mk.17 15-megaton thermonuclear bomb could be carried.

10 February 1960: Delta Air Lines’ Superintendant of Flight Operations, Captain Thomas Prioleau Ball, Jr., made the delivery flight of Delta’s first Convair 880 jet airliner, Ship 902, named Delta Queen, FAA registration N8802E, from San Diego, California, to Miami, Florida. Other members of the flight crew were Captain James H. Longing, co-pilot, and First Officer Richard E. Tidwell, flight engineer.

Newspapers reported that Delta Queen‘s wheels started rolling on the runway at San Diego’s Lindbergh Field (SAN) at 10:11:46 a.m., Pacific Standard Time (18:11:46 UTC). The airplane took of and climbed to its cross-country cruising altitude of 33,000 feet (10,058 meters). The Convair 880 landed at Miami International Airport (MIA) at 4:42:08 p.m., Eastern Standard Time (21:42:08 UTC). The official flight time was 3 hours, 31 minutes, 54 seconds, for an average speed of 641.77 miles per hour (1,032.83 kilometers per hour) over the 2,266 mile (3,647 kilometers) route. This was a new United States National Record for Speed Over a Commercial Airline Route. The 880 cut 27 minutes, 1 second, off the time of an Eastern Air Lines Douglas DC-8B over the same route, 4 January 1960.

Screen Shot 2015-02-11 at 10.40.18Delta Queen was placed in scheduled service 15 May 1960.

The Convair 880 was a four-engine, swept-wing turbojet-powered commercial airliner. It was operated by a flight crew of three and could carry up to 110 passengers. The Convair 880-22-M was a modified version of the standard 880-22, intended for shorter range operations. It had leading-edge slats, a higher maximum takeoff weight, stronger landing gear, a tail skid and an improved anti-lock braking system. The Convair 880 was so-named because its design top speed was 880 feet per second (600 miles per hour, or 966 kilometers per hour), faster than its Boeing 707 or Douglas DC-8 rivals.

The airplane was 129 feet, 4 inches (39.421 meters) long with a wingspan of 120 feet (36.576 meters) and overall height of 36 feet, 3.75 inches (11.068 meters). The 880 had an empty weight of 94,000 pounds (42,638 kilograms) and maximum takeoff weight was 191,000 pounds (86,636 kilograms).

The Convair 880-22-M was powered by four General Electric CJ805-3B turbojet engines. The CJ805-3B is a single-shaft, axial-flow turbojet with a 17-stage compressor section and 3-stage turbine, based on the military J79. The engine has a maximum continuous power rating of 9,800 pounds of thrust (43.593 kilonewtons) at Sea Level, and 11,650 pounds (51.822 kilonewtons) for Takeoff. The CJ805-3B is 9 feet, 2.4 inches (2.804 meters) long, 3 feet, 3.9 inches (1.013 meters) wide and 4 feet, 0.8 inches (1.240 meters) high. It weighs 2,875 pounds (1,304 kilograms).

The 880-22-M had a cruise speed of 0.82 Mach (556 miles per hour/895 kilometers per hour) at 30,000 feet (9,144 meters). The service ceiling was 41,000 feet (12,497 meters). Maximum range was 5,056 miles (8,137 kilometers).

The Convair Division of General Dynamics built 65 Convair 880 airliners at San Diego, California, between 1959 and 1962. Delta Air Lines retired its last one in January 1974.

Captain Thomas P. Ball

Thomas Prioleau (“Pre”) Ball, Jr., was a legendary airline captain. He was born 6 September 1906 at Norfolk, Virginia, the second son of Thomas Prioleau Ball, a bookkeeper, and Agnes Mae Bell Ball. He grew up in Florida. Ball learned to fly in 1928, soloing in a World War I Curtiss “Jenny” biplane.

Thomas P. Ball, Jr., married Miss Theresa Augusta Daniel at the Church of the Good Shepherd in Jacksonville, Florida, 27 December 1930. They would have to sons, Thomas Prioleaux Ball III and Espy Daniel Ball.

Ball worked as a station manager for Delta Air Lines at Charleston, South Carolina, and was hired as a copilot by the airline in 1936.

Soon after the United States entered World War II, Ball was commissioned as a second lieutenant in the U.S. Army Air Corps. By the end of the war, he had risen to the rank of colonel, serving as the Chief of the Prevention and Investigation Division of the Army’s Office of Flying Safety.

After the War, Ball returned to Delta Air Lines as a captain and soon became the chief pilot, dedicated to the meticulous training of the company’s pilots. In 1969, Ball became Delta’s Vice President of Flight Operations. On 25 May 1970, Ball was aboard Delta Flight 199, a Convair 880 under the command of Captain Harris B. Wynn, when it was hijacked to Cuba.

Four U.S. National Speed Records which were set by Captain Ball remain current. In addition to the record set with the Convair 880, on 6 November 1948, Ball flew a Delta Air Lines Douglas DC-6 from Los Angeles, California, to Charleston, South Carolina, in 6 hours, 24 minutes, 32 seconds, at an average speed of 344.19 miles per hour (553.92 kilometers per hour). On 18 March 1954, he flew a Douglas DC-7 from Los Angeles to Jacksonville, Florida, in 05:29:33, averaging 392.25 miles per hour (631.27 kilometers per hour). Finally, on 24 February 1962, Captain Ball flew a Douglas DC-8 from Miami, Florida, to Atlanta, Georgia, in 01:28:11, for an average of 406.1 miles per hour (653.56 kilometers per hour).

After making the delivery flight of the company’s first Boeing 747, Ball grounded himself when he noticed a deterioration in his eyesight. Thomas Prioleau Ball retired from Delta in 1971. He passed away in 2006 at the age of 99 years.

Convair 880-22-M N8802E, Delta Queen, (c/n 7) remained in service with Delta Air Lines until 1973 when it was sold to Boeing as part of exchange for an order of new Boeing 727-200 airliners. It was then sold to Transexecutive Aviation in 1974 and reregistered as N55NW. In 1976, the 880 flew as a charter airliner for Bahama World. It was then converted to a cargo freighter operating in the Caribbean. In 1979 the Convair was transferred to Groth Air Service, Inc., Castalia, Iowa, and assigned a new FAA registration, N880SR. The record-setting airliner was damaged beyond repair in a fire at Licenciado Benito Juarez International Airport, Mexico City, in May 1983.

1st Lt. Gary E. Foust

2 February 1970: At approximately 9:50 a.m., three Convair F-106A Delta Dart supersonic interceptors of the 71st Fighter Interceptor Squadron, 24th Air Division, based at Malmstrom Air Force Base, Montana, were engaged in an air combat training mission.

1st Lieutenant Gary Eugene Foust was flying F-106A-100-CO 58-0787, an airplane usually flown by the squadron’s maintenance officer, Major Wolford.

During the simulated combat, Lt. Foust entered into a vertical climb with his “opponent,” Captain Tom Curtis, who was also flying an F-106, and they both climbed to about 38,000 feet (11,600 meters) while using a “vertical rolling scissors” maneuver as each tried to get into a position of advantage.

Lt. Foust’s interceptor stalled and went in to a flat spin. Captain Curtiss described it: “The aircraft looked like the pitot tube was stationary with the aircraft rotating around it. Very flat and rotating quite slowly.”

Foust tried all the recovery procedures but could not regain control of the Delta Dart. With no options remaining, at about 15,000 feet (4,572 meters), Foust ejected from the apparently doomed airplane.

This F-106A (S/N 58-0787) was involved in an unusual incident. During a training mission, it entered an flat spin forcing the pilot to eject. Unpiloted, the aircraft recovered on its own and miraculously made a gentle belly landing in a snow-covered field. (U.S. Air Force photo)

After the pilot ejected, the F-106 came out of the spin and leveled off.  With its engine still running, -787 continued flying, gradually descending, until it slid in to a landing in a wheat field near Big Sandy, Montana. Eventually the airplane ran out of fuel and the engine stopped at about 12:15 p.m.

Lieutenant Foust safely parachuted into the mountains and was soon rescued.

58-0787 was partially disassembled by a maintenance team from Hill Air Force Base, Utah, and loaded on to a rail car. It was then transported to the Sacramento Air Logistics Center at McClellan Air Force Base, Sacramento, California, where it was repaired and eventually returned to flight status with the 49th Fighter Interceptor Squadron, 21st Air Division, at Griffiss Air Force Base, New York.

After the Convair Delta Dart was retired from active service, 58-0787 was sent to the National Museum of the United States Air Force, Wright-Patterson Air Force Base, Ohio.

The Convair F-106A Delta Dart was the primary all-weather interceptor of the United States Air Force from 1959 to 1988, when it was withdrawn from service with the Air National Guard. It was a single-seat, single-engine delta-winged aircraft capable of speeds above Mach 2.

The airplane was a development of the earlier F-102A Delta Dagger, and was initially designated F-102B. However, so many changes were made that it was considered to be a new aircraft.

The F-106A is 70 feet, 8.78 inches (21.559 meters) long with a wingspan of 38 feet, 3.5 inches (11.671 meters). The total area of the delta wing is 697.83 square feet (64.83 square meters). The angle of incidence was 0° and there was no dihedral. The leading edges were swept aft 60°. The top of the vertical fin was 20 feet, 3.3 inches (6.180 meters) high. The Delta Dart weighs 23,646 pounds (10,726 kilograms) empty, and has a maximum takeoff weight (MTOW) of 38,729 pounds (17,567 kilograms).

The F-106 was powered by a Pratt & Whitney J75-P-17 afterburning turbojet engine. The J75-P-17 was a two-spool axial-flow turbojet engine with afterburner. It used a 15-stage compressor section (8 high- and 7 low-pressure stages) and a 3-stage turbine section (1 high- and 2-low pressure stages). The J75-P-17 had a maximum continuous power rating of 14,100 pounds of thrust (62.72 kilonewtons), and military power rating of 16,100 pounds (71.62 kilonewtons) (30-minute limit). It produced a maximum of 24,500 pounds (108.98 kilonewtons) with afterburner (5-minute limit). The engine was 3 feet, 8.25 inches (1.124 meters) in diameter, 19 feet, 9.6 inches long (6.035 meters), and weighed 5,875 pounds (2,665 kilograms).

The interceptor has a cruise speed of 530 knots (610 miles per hour/982 kilometers per hour). and a maximum speed of 1,153 knots 1,327 miles per hour/2,135 kilometers per hour) at 35,000 feet (10,668 meters). The F-106A had a service ceiling is 53,800 feet (16,398 meters) and a rate of climb of 48,900 feet per minute (248 meters per second). Its combat radius was 530 nautical miles (610 statute miles/982 kilometers) and the maximum ferry range was 1,843 nautical miles (2,121 statute miles/3,413 kilometers).

The Delta Dart was armed with four GAR-3A radar-homing, or -4A (AIM-4F, -4G) infrared-homing Falcon air-to-air guided missiles, and one MB-1 (AIM-2A) Genie unguided rocket with a 1.5 kiloton W-25 nuclear warhead. The missiles were carried in an internal weapons bay. In 1972, the General Electric M61A1 Vulcan 20mm cannon was added to the rear weapons bay with 650 rounds of ammunition. (The number of gun-equipped Delta Darts is uncertain.)

Convair built 342 F-106 interceptors. 277 were F-106As and the remainder were F-106B two-seat trainers.

14 January 1961: Lt. Col. Harold E. Confer, Lt. Col. Richard Weir and Major Howard Bialas, flying Convair B-58A-10-CF Hustler 59-2441, Roadrunner, obliterated the FAI closed-course speed records established only two days earlier by another B-58 crew flying 59-2442. They averaged 2,067.58 kilometers per hour (1,284.73 miles per hour) over a 1,000 kilometer closed circuit, more than 200 miles per hour faster, and set three Fédération Aéronautique Internationale records. They were awarded the Thompson Trophy.

59-2441 was sent to The Boneyard in 1970, and along with its sister, 59-2442, scrapped in 1977.

The B-58 Hustler was a high-altitude Mach 2 strategic bomber which served with the United States Air Force from 1960 to 1970. It was crewed by a pilot, navigator/bombardier and a defensive systems operator located in individual cockpits. The aircraft is a delta-winged configuration similar to the Convair F-102A Delta Dagger and F-106 Delta Dart supersonic interceptors.

The Hustler is 96 feet, 10 inches (29.515 meters) long, with a wing span of 56 feet, 10 inches (17.323 meters) and an overall height of 31 feet 5 inches (9.576 meters). The wing’s leading edge is swept back at a 60° angle and the fuselage incorporates the “area rule” which resulted in a “wasp waist” or “Coke bottle” shape for a significant reduction in aerodynamic drag. The airplane’s only control surfaces are two “elevons” and a rudder, and there are no flaps. Four General Electric J79-GE-5 afterburning turbojet engines, producing 15,000 pounds of thrust, each, are suspended under the wings from pylons. The bomber had a cruise speed of 610 miles per hour (981.7 kilometers per hour) and a maximum speed of 1,325 miles per hour (2,132.4 kilometers per hour). The service ceiling is 64,800 feet (19,751 meters). Unrefueled range is 4,400 miles (7,081 kilometers). Maximum weight is 168,000 pounds (76,203.5 kilograms).

The B-58 weapons load was a combination of W-39,  B43 or B61 nuclear bombs. The weapons could be carried in a jettisonable centerline pod, which also carried fuel. The smaller bombs could be carried on underwing hardpoints. There was a defensive 20 mm M61 rotary cannon mounted in the tail, with 1,200 rounds of ammunition and controlled by the Defensive Systems Officer.

12 January 1961: Major Henry J. Deutschendorf, United States Air Force, 43rd Bomb Wing, Strategic Air Command, flew from Carswell Air Force Base, Texas, to Edwards Air Force Base, California, with a Convair B-58A-10-CF Hustler, serial number 59-2442, named  Untouchable.

There, he flew two laps of a 1,000 kilometer circuit between Edwards and Yuma, establishing six new Fédération Aéronautique Internationale (FAI) speed records at an average of 1,708.82 kilometers per hour (1,061.81 miles per hour).

Major Deutschendorf and his crew, Captain Raymond R. Wagener, Defensive Systems Officer, and Captain William L. Polhemus, Radar Navigator/Bombardier, were each awarded the Distinguished Flying Cross.

(Major Deutschendorf was the father of Henry J. Deutschendorf, Jr., who was better known by his stage name, “John Denver.”)

Untouchable, the record-setting Mach 2+ strategic bomber, was sent to The Boneyard at Davis-Monthan AFB, Tucson, Arizona, in 1969. 59-2442 was scrapped in 1977.

The Convair B-58 Hustler was a high-altitude, Mach 2+ strategic bomber which served with the United States Air Force from 1960 to 1970. It was crewed by a pilot, navigator/bombardier and a defensive systems operator located in individual cockpits. The aircraft has a delta-winged configuration similar to Convair’s F-102A Delta Dagger and F-106 Delta Dart supersonic interceptors.

The Hustler is 96 feet, 10 inches (29.515 meters) long, with a wing span of 56 feet, 10 inches (17.323 meters) and overall height of 31 feet 5 inches (9.576 meters). The wings’ leading edge is swept back at a 60° angle and the fuselage incorporates the “area rule” which resulted in a “wasp waist” or “Coke bottle” shape for a significant reduction in aerodynamic drag. The airplane’s only control surfaces are two “elevons” and a rudder. There are no flaps.

The B-58A was powered by four General Electric J79-GE-5 axial-flow afterburning turbojet engines, suspended under the wings from pylons. This was a single-shaft engine with a 17-stage compressor and 3-stage turbine, rated at 10,300 pounds of thrust (45.82 kilonewtons), and 15,600 pounds (69.39 kilonewtons) with afterburner. The J79-GE-5 was 16 feet, 10.2 inches (5.136 meters) long and 3 feet, 2.0 inches (0.965 meters) in diameter.

The bomber had a cruise speed of 610 miles per hour (981.7 kilometers per hour) and a maximum speed of 1,325 miles per hour (2,132.4 kilometers per hour). The service ceiling is 64,800 feet (19,751 meters). Unrefueled range is 4,400 miles (7,081 kilometers). Maximum weight is 168,000 pounds (76,203.5 kilograms).

The B-58 weapons load was a combination of W-39,  B43 or B61 nuclear bombs. The large weapons could be carried in a jettisonable centerline pod, which also carried fuel, and the smaller bombs could be carried on hardpoints. There was a defensive 20 mm M61 rotary cannon mounted in the tail with 1,200 rounds of ammunition. The gun was controlled remotely by the Defensive Systems Officer.
