30 May 1949: While testing a radical “flying wing” aircraft, the Rolls-Royce Nene-powered Armstrong Whitworth A.W.52, TS363, test pilot John Oliver (“Jo”) Lancaster, D.F.C., encountered severe pitch oscillations in a 320 mile per hour (515 kilometer per hour) dive. Lancaster feared the aircraft would disintegrate.
In the very first use of the Martin-Baker Mk1 ejection seat in an actual emergency, Lancaster fired the seat and was safely thrown clear of the aircraft. He parachuted to safety and was uninjured. The aircraft was destroyed.

The Martin-Baker MK1 was developed by Bernard Ignatius (“Benny”) Lynch, B.E.M., a ground fitter for Martin-Baker Aircraft Co., Ltd., who tested it himself, ejecting from a test aircraft at 420 miles per hour (676 kilometers per hour) and 12,000 feet (3,658 meters). He eventually made more than 30 ejections. Lynch was awarded the British Empire Medal in the King’s 1948 New Year Honours.
The seat was launched with a two cartridge ejection gun, with an initial velocity of 60 feet per second (18.3 meters per second). After rising 24 feet (7.3 meters), a static line fired a drogue gun, deploying a 24-inch (0.61 meter) drogue parachute to stabilize the seat. The static line also actuated the seat’s oxygen supply. The pilot manually released himself from the seat, and opened his parachute by pulling the rip cord.

As of 31 May 2023, 7,695 airmen worldwide have been saved by Martin-Baker ejection seats. 69 of these were with the Mk1.
Armstrong Whitworth AW.52, TS363
The Armstrong Whitworth A.W.52 was an all-metal, experimental two-place, twin engine, tailless “flying wing” airplane with retractable tricycle landing gear. The concept was that of an air mail aircraft. The cockpit was pressurized and offset to the left of the aircraft centerline. The two turbojet engines are in nacelles positioned almost entirely within the wing. The A.W.52 was 37 feet, 4 inches (11.354 meters) long with a wingspan of 90 feet (27.4 meters) and height of 14 feet, 4 inches (4.343 meters).
The wings were swept in two sections. From the fuselage to just outboard of the engines, the leading edges were swept to 17° 34′. From that point, called “the knuckle” in contemporary descriptions, the sweep increased to 34° 6′ to the wing tips. (A line from the ¼-chord points at the wing root and tip gave a sweep of 24¾°.) The inner wing had no dihedral, and the outer wing had 1° dihdreal. The wing incorporated a -5° twist between the root and tip. The total wing area was 1,314 square feet (122.1 square meters). Vertical fins and rudders are attached at the wing tips.

The airplane incorporated boundary layer control to delay the wing stalling in the area of the ailerons. It also used engine heat for deicing,
The A.W.52 had a empty weight of 19,662 pounds (9,055 kilograms) total weight of 32,700 pounds (14,832 kilograms).
The A.W.52 was powered by two Rolls-Royce RB.41 Nene Mk.I engines. The Nene was a single-shaft turbojet developed from the RB.40 Derwent. It had first been run in October 1944. The Nene was considerably larger than the Derwent and produced nearly double the thrust. It had a single-stage centrifugal-flow compressor and single-stage axial-flow turbine. It was rated at 5,000 pounds of thrust (22.24 kilonewtons) at 12,400 r.p.m. for takeoff. The second A.W.52 prototype, TS368, used two Derwent engines.
The A.W.52 had a maximum speed at Sea Level of 500 miles per hour (805 kilometers per hour) and 480 miles per hour (772 meters) at 36,000 feet (10,973 meters). Its maximum range was 1,500 miles (2,414 kilometers), flying 330 miles per hour (531 kilometers per hour) at 36,000 feet (10,973 meters).

A Boeing B-17F Flying Fortress takes off from Boeing Field, Seattle, Washington, 1942.
30 May 1942: The Boeing B-17F Flying Fortress makes its first flight. B-17F-1-BO 41-24340 was the first of a new series of the famous World War II bomber. While visually similar to the B-17E, it had more than 400 improvements based on early wartime experience with the B-17D and B-17E.
The Boeing B-17F Flying Fortress was a four-engine heavy bomber operated by a flight crew of ten. It was 74 feet, 8.90 inches (22.781 meters) long with a wingspan of 103 feet, 9.375 inches (31.633 meters) and an overall height of 19 feet, 1.00 inch (5.187 meters). The wings have 3½° angle of incidence and 4½° dihedral. The leading edge is swept aft 8¾°. The total wing area is 1,426 square feet (132.48 square meters). The horizontal stabilizer has a span of 43 feet (13.106 meters) with 0° incidence and dihedral. Its total area, including elevators, is 331.1 square feet (12.18 square meters).

It was assigned to the 331st Bombardment Squadron), 94th Bombardment Group (Heavy), marked QE Z, and named “Nip ‘n’ Tuck.” This bomber crashed at Évreaux, Normandy, France, 14 July 1943. 8 crew members were captured, but 2 evaded. (Boeing Airplane Company)
The B-17F had an empty weight of 32,962 pounds (14,951 kilograms), maximum design gross weight, 48,726 pounds (22,102kilograms) basic, and the maximum takeoff weight was 65,000 pounds (29,484 kilograms).

The B-17F was powered by four air-cooled, supercharged, 1,823.129-cubic-inch-displacement (29.876 liters) Wright Cyclone C9GC (R-1820-97) nine-cylinder radial engines with a compression ratio of 6.70:1. (Early production B-17Fs were equipped with the Wright Cyclone G666A (R-1820-65). Both variants had the same power ratings.) The engines were equipped with remote General Electric B-22 turbochargers capable of 24,000 r.p.m. The R-1820-97 was rated at 1,000 horsepower at 2,300 r.p.m. at Sea Level, and 1,200 horsepower at 2,500 r.p.m. for takeoff. The engine could produce 1,380 horsepower at War Emergency Power. 100-octane aviation gasoline was required. The Cyclones turned three-bladed, constant-speed, Hamilton-Standard Hydromatic propellers with a diameter of 11 feet, 7 inches (3.835 meters) through a 0.5625:1 gear reduction. The R-1820-97 engine is 47.80 inches (1.214 meters) long and 55.10 inches (1.399 meters) in diameter. It weighs 1,315 pounds (596 kilograms).

The B-17F had a cruising speed of 200 miles per hour (322 kilometers per hour). The maximum speed was 299 miles per hour (481 kilometers per hour) at 25,000 feet (7,620 meters), though with War Emergency Power, the bomber could reach 325 miles per hour (523 kilometers per hour) at 25,000 feet for short periods. The service ceiling was 37,500 feet (11,430 meters).
With a normal fuel load of 1,725 gallons (6,530 liters) the B-17F had a maximum range of 3,070 miles (4,941 kilometers). Two “Tokyo tanks” could be installed in the bomb bay, increasing capacity by 820 gallons (3,104 liters). Carrying a 6,000 pound (2,722 kilogram) bomb load, the range was 1,300 miles (2,092 kilometers).

The B-17F Flying Fortress was armed with up to 13 air-cooled Browning AN-M2 .50-caliber machine guns. Power turrets mounting two guns each were located at the dorsal and ventral positions. A pair of machine guns were mounted in the tail, and single guns on flexible mounts were placed in the nose, radio compartment, and right and left waist positions.

An 8th Air Force study found that body armor prevented approximately 74 percent of wounds in protected areas. Once adopted in World War II, body armor reduced the rate of wounds sustained by aircrews on missions by 60 percent. Besides saving lives, body armor boosted aircrew morale during stressful missions over enemy territory.” (U.S. Air Force)A gunner fires the two Browning .50 caliber machine guns of his ball turret.

The maximum bomb load of the B-17F was 20,800 pounds (9434.7 kilograms) over very short ranges. Normally, 4,000–6,000 pounds (1,815–2,722 kilograms) of high explosive bombs were carried. The internal bomb bay could be loaded with a maximum of eight 1,600 pound (725.75 kilogram) bombs. Two external bomb racks mounted under the wings between the fuselage and the inboard engines could carry one 4,000 pound (1,814.4 kilogram) bomb, each, though this option was rarely used.
Probably the best known individual combat airplane, this is Boeing B-17F-10-BO Flying Fortress 41-22485, Memphis Belle, in flight over England, 1943. (U.S. Air Force)
The B-17 Flying Fortress first flew in 1935, and was in production from 1937 to 1945. 12,731 B-17s were built by Boeing, Douglas Aircraft Company and Lockheed-Vega. (The Manufacturer Codes, -BO, -DL and -VE, follow the Block Number in each airplane’s type designation.) 3,405 of the total were B-17Fs, with 2,000 built by Boeing, 605 by Douglas and 500 by Lockheed-Vega.
Only three B-17F Flying Fortresses remain in existence.

30 May 1912: Wilbur Wright, co-inventor with his brother Orville of the Wright Flyer, the first powered, controllable, heavier-than-air vehicle, died at the family home in Dayton, Ohio, of typhoid fever.
His father wrote:
May 30, 1912
This morning at 3:15, Wilbur passed away, aged 45 years, 1 month, and 14 days.
A short life, full of consequences.
An unfailing intellect, imperturbable temper, great self-reliance and as great modesty, seeing the right clearly, pursuing it steadfastly, he lived and died.

29 May 1963: Lockheed Test Pilot Anthony W. “Tony” LeVier and his 18-year-old daughter, Toniann LeVier, flew the company’s two-place TF-104G Starfighter demonstrator, FAA registration N104L, from Air Force Plant 42, Palmdale, California, to Andrews Air Force Base, Maryland. They made fuel stops at Kirkland Air Force Base, Albuquerque, New Mexico, Tinker Air Force Base, Oklahoma City, Oklahoma, and Wright-Patterson Air Force Base, Dayton Ohio.

The Oxnard Press Courier reported:
PALMDALE, Calif. — Toni Ann LeVier, 18, recently earned the title of World’s Fastest Teen-ager after a scorching Mach 2 (twice the speed of sound) flight in the front cockpit of a Talley Corporation equipped TF-104G Super Starfighter.
The back-seat driver of the Lockheed aircraft A.W. (Tony) LeVier, her father.
Director of flying operations for Lockheed-California Company, Tony took Toni for a double crack at the sound barrier in the supersonic corridor near Edwards Air Force Base…
The teen-age fledgling flier handled the TF-104G controls during the Mach 2 dash.
Flying the stub-wing fighter was a giant step for Toni, who holds a student pilot’s license.
She started flying lessons in January and has 35 hours in a Beechcraft Musketeer light plane, whose docile 140-m.p.h. speed is about one-tenth that of the TF-104G.
A student at John Muir High School in Pasadena, the pert Mach 2 Miss offered this reaction to the flight:
“I’m still tingling. That sudden surge of power made me feel like we were taking off for outer space, but it’s just as easy to fly as a light plane.”
The company-owned TF-104G they flew is being assigned to Andrews AFB near Washington for a series of demonstrations to U.S. Air Force officials.
Toni volunteered to help Pop ferry the airplane on the cross-country hop.
They plan to leave Friday morning. Stops are scheduled at USAF bases at Albuquerque, Oklahoma City (where they will remain overnight after a noon arrival), and at Dayton, Ohio.
Toni is no stranger to military bases.
She was named “Miss Starfighter” by F-104 pilots of the 479th Tactical Fighter Wing, George AFB, Calif., for Armed Forces Week.
at Andrews AFB Saturday the LeViers will turn the 1500-m.p.h Super Starfighter over to a Lockheed Demonstration team.
Then — for Toni — it’s back to flying a school desk.
Toniann LeVier on the cover of This Week Magazine, 28 September 1963.
Toniann LeVier was born 21 September 1944 in Los Angeles County, California. She was the first of two daughters of Anthony W. (“Tony”) Levier, a test pilot for Lockheed in Burbank, California, and Neva Jean Ralph LeVier. Miss LeVier attended John Muir High School in Pasadena, California, where she participated in the Adelphians, the Civil Affairs Council, Fine Arts Council and the Senior Class Council. She graduated in 1963. Later, she studied at Cabrillo College, Aptos, California.
Miss LeVier married David M. Logan, a real estate agent from La Cañada, California, on 11 July 1964. On 24 June 1978, she married her second husband, Theodore E. Posch, in Orange, California. On 21 June 2003, she married Richard Samuel Almaz, a chef, in Las Vegas, Nevada.
Today, Mrs. LeVier-Almaz works as a massage therapist. She and her husband live in Aptos.

N104L is the same aircraft in which Jackie Cochran set a Fédération Aéronautique Internationale (FAI) speed record of 1,273.12 miles per hour (2,048.88 kilometers per hour) over a 15/25 kilometer straight course, 12 April 1963.¹ 1,203.94 miles per hour over a 100 kilometer closed circuit on 1 May 1963.²
N104L, originally registered N90500, was retained by Lockheed for use as a customer demonstrator to various foreign governments. In 1965 Lockheed sold N104L to the Koninklijke Luchtmacht (the Royal Netherlands Air Force), where it served as D-5702 until 1980. It next went to the Türk Hava Kuvvetleri (Turkish Air Force), identified as 4-702. The record-setting Starfighter was retired in 1989 and after several years in storage, was scrapped.

29 May 1951: Pan American World Airways Captain Charles F. Blair, Jr., flew a modified North American Aviation P-51C-10-NT Mustang, NX12012, Excalibur III, from Bardufoss, Norway to Fairbanks, Alaska, via the North Pole. He flew the 3,260 miles (5,246.5 kilometers) non-stop in 10 hours, 27 minutes.
After departing Bardufoss at 3:58 p.m., Captain Blair flew north along the E. 20° meridian until crossing the North Pole at an altitude of 22,000 feet (6,706 meters), then south along the W. 160° meridian until reaching N. 70° latitude, and then southeast to Fairbanks.
During the transpolar flight, the Mustang was subjected to air temperatures as low as -25 °F. (-31.6 °C.).

Captain Blair navigated by using a system of pre-plotted sun lines calculated by Captain Phillip Van Horns Weems, U.S. Navy (Ret.), as a magnetic compass was useless near the Pole and there were no radio navigation aids available.
Charles Blair used this Astrocompass Mark II on his transpolar flight. It is in the collection of the Smithsonian Institution National Air and Space Museum. (NASM2012-02107)
Blair was presented the Harmon International Trophy by President Harry S. Truman, in a ceremony at the White House, 18 November 1952. The Harmon awards are for “the most outstanding international achievements in the art and/or science of aeronautics for the previous year, with the art of flying receiving first consideration.”

Charles Blair was commissioned in the United States Naval Reserve in 1931. He was promoted to lieutenant, junior grade, in 1937. During World War II, Blair served as a transport pilot in the U.S. Navy and rose to the rank of captain.
Blair resigned from the Navy in 1952 and the following year accepted a commission in the U.S. Air Force Reserve with the rank of colonel. In 1959 he was promoted to brigadier general.
While serving as a reserve officer, Charlie Blair continued his civilian career as an airline pilot for United Airlines, American Overseas Airlines, and then with Pan American.
Captain Blair was married to actress Maureen O’Hara, whom he had met during one of his 1,575 transatlantic crossings.
Excalibur III is a Dallas, Texas-built North American Aviation P-51C-10-NT Mustang, one of a group of 400 fighters which had been contracted on 5 March 1943. Its North American Aviation serial number is 111-29080, and the U.S. Army Air Forces assigned it serial number 44-10947.
After World War II, 44-10947 was purchased by Paul Mantz, and the Civil Aeronautics Administration registered it as NX1202. Mantz had it painted red and named it Blaze of Noon. Paul Mantz flew NX1202 to win the 1946 and 1947 Bendix Trophy Races. Flown by Linton Carney and renamed The Houstonian, NX1202 placed second in the 1948 Bendix race, and with “Fish” Salmon in the cockpit, it took third place in 1949. Paul Mantz had set several speed records with the Mustang before selling it to Pan American World Airways, Inc., Blair’s employer. Blair named the Mustang Stormy Petrel, but later changed it to Excalibur III.
To increase the Mustang’s range for these long-distance flights, Mantz had removed the standard 90-gallon pressure-molded Firestone self-sealing tanks from each wing and converted the entire wing to a fuel tank (what is known as a “wet wing”).

The P-51B and P-51C Mustang are virtually Identical. The P-51Bs were built by North American Aviation, Inc, at Inglewood, California. P-51Cs were built at North American’s Dallas, Texas plant. They were 32 feet, 2.97 inches (9.829 meters) long, with a wingspan of 37 feet, 0.31-inch (11.282 meters) and overall height of 13 feet, 8 inches (4.167 meters) high. The fighter had an empty weight of 6,985 pounds (3,168 kilograms) and a maximum gross weight of 11,800 pounds (5,352 kilograms).

P-51Bs and Cs were powered by a right-hand tractor, 1,649-cubic-inch-displacement (27.04-liter) liquid-cooled, supercharged, Packard V-1650-3 or -7 Merlin single overhead cam (SOHC) 60° V-12 engine which produced 1,380 horsepower at Sea Level, at 3,000 r.p.m and 60 inches of manifold pressure (V-1650-3) or 1,490 horsepower at Sea Level, turning 3,000 r.p.m. with 61 inches of manifold pressure (V-1650-7). (Military Power rating, 15 minute limit.) These engines were license-built versions of the Rolls-Royce Merlin 63 and 66. The engine drove a four-bladed Hamilton Standard Hydromatic constant-speed propeller with a diameter of 11 feet, 2 inches (3.404 meters) through a 0.479:1 gear reduction.
The P-51B/C had a cruise speed of 362 miles per hour (583 kilometers per hour) and the maximum speed was 439 miles per hour (707 kilometers per hour) at 25,000 feet (7,620 meters), slightly faster than the more numerous P-51D Mustang. The service ceiling was 41,900 feet (12,771 meters). With internal fuel the combat range was 755 miles (1,215 kilometers).
Identical to the Inglewood, California-built North American Aviation P-51B Mustang, this is a Dallas, Texas-built P-51C-1-NT, 42-103023. (North American Aviation, Inc.)
In military service, armament consisted of four Browning AN/M2 .50-caliber machine guns, mounted two in each wing, with 350 rounds per gun for the inboard guns and 280 rounds per gun for the outboard.
1,988 P-51B Mustangs were built at North American’s Inglewood, California plant and another 1,750 P-51Cs were produced at Dallas, Texas. This was nearly 23% of the total P-51 production.
Though the P-51D with its bubble canopy was built in far greater numbers during World War II, the earlier P-51B and P-51C Mustangs were actually faster, so many surplus airplanes were used for racing and record attempts after the war.
In 1952, Pan American World Airways donated Excalibur III to the Smithsonian Institution. Today, completely restored, it is on display at the Steven F. Udvar-Hazy Center in Chantilly, Virginia.
