Cessna 180 serial number 30238 was built by the Cessna Aircraft Company, Inc., Wichita, Kansas, in 1953, and registered N1538C, the first year of production for the model. It was the 238th of 640 Model 180s that were built during the first year of production. 6,193 were built by the time production came to an end in 1986. N1538C was purchased for Jerrie Mock in 1963, with a total of 990 hours on the engine and airframe. The passenger seats were removed and replaced with additional fuel tanks. Additional radios and instruments were installed.

17 April 1956: Lockheed Aircraft Corporation rolled out the very first production F-104A Starfighter, 55-2956, at Air Force Plant 42, Palmdale, California. This airplane, one of the original seventeen pre-production YF-104As, incorporated many improvements over the XF-104 prototype, the most visible being a longer fuselage.
Once the configuration was finalized, 55-2956 was the first YF-104A converted to the F-104A production standard. In this photograph, the F-104’s secret engine intakes are covered by false fairings.

The Lockheed F-104A Starfighter was a single-place, single-engine supersonic interceptor. It was designed by a team lead by the legendary Clarence L. “Kelly” Johnson. The F-104A was 54 feet, 8 inches (16.662 meters) long with a wingspan of 21 feet, 9 inches (6.629 meters) and overall height of 13 feet, 5 inches (4.089 meters). It had an empty weight of 13,184 pounds (5,980.2 kilograms), combat weight of 17,988 pounds (8,159.2 kilograms), gross weight of 22,614 pounds (10,257.5 kilograms) and a maximum takeoff weight of 25,840 pounds (11,720.8 kilograms). Internal fuel capacity was 897 gallons (3,395.5 liters).
The F-104A was powered by a single General Electric J79-GE-3A engine, a single-spool axial-flow afterburning turbojet, which used a 17-stage compressor and 3-stage turbine. The J79-GE-3A is rated at 9,600 pounds of thrust (42.70 kilonewtons), and 15,000 pounds (66.72 kilonewtons) with afterburner. The engine is 17 feet, 3.5 inches (5.271 meters) long, 3 feet, 2.3 inches (0.973 meters) in diameter, and weighs 3,325 pounds (1,508 kilograms).
The F-104A had a maximum speed of 1,037 miles per hour (1,669 kilometers per hour) at 50,000 feet (15,240 meters). Its stall speed was 198 miles per hour (319 kilometers per hour). The Starfighter’s initial rate of climb was 60,395 feet per minute (306.8 meters per second) and its service ceiling was 64,795 feet (19,750 meters).

Armament was one General Electric M61 Vulcan six-barreled revolving cannon with 725 rounds of 20 mm ammunition. An AIM-9B Sidewinder heat-seeking air-to-air missile could be carried on each wing tip, or a jettisonable fuel tank with a capacity of 141.5 gallons (535.6 liters).
Lockheed built 153 of the F-104A Starfighter initial production version. A total of 2,578 F-104s of all variants were produced by Lockheed and its licensees, Canadair, Fiat, Fokker, MBB, Messerschmitt, Mitsubishi and SABCA. By 1969, the F-104A had been retired from service. The last Starfighter, an Aeritalia-built F-104S ASA/M of the Aeronautica Militare Italiana, was retired in October 2004.

The C-69 departed Lockheed Air Terminal, Burbank, California, at 3:56:45 a.m., Pacific War Time. The other crew members were Edward T. Bolton, Navigator; R. L. Proctor, Flight Engineer; and Charles L. Glover, Radio Operator. Also on board were 12 passengers representing the Air Corps, T.W.A. and Lockheed.¹
The Dayton Herald reported:
Constellation Sets Record; To Be in Dayton Thursday
(BULLETIN)
WASHINGTON, April 17.—(UP)—The giant transport Constellation landed at Washington National Airport at 1:59 p.m. EWT today, setting a new trans-continental airplane speed record.
The huge four-motor transport made the crossing from Burbank, Calif., in approximately 7 hours and three minutes on the basis of unofficial timing. Howard Hughes, who set the previous record, piloted the plane here for delivery to the Army.
The Constellation, Transcontinental and Western Airline’s (TWA) super transport, which left Burbank, Calif., today for delivery to the air transport command at Washington, will fly to Wright Field Thursday afternoon, Material Command officials said here.
Considered the largest land-based cargo plane in the country, the “Constellation” took off from Lockheed Air Terminal at 5:56 a.m., (Dayton time) today with veteran pilot Howard Hughes and Jack Frye, TWA president, co-designers of the plane, as pilot and co-pilot, respectively. It passed over Butler Mo., 50 miles south of Kansas City, at 10:20 a.m. (Dayton time).
Materiel Command officials said the plane was expected to make the trip in nine hours. They estimated she could fly from Los Angeles, Calif., to Honolulu in 12 hours.
Also aboard were Lt. Col. Clarence Shoop, resident Material Command inspector at the Lockheed Burbank plant, 17 Lockheed and TWA technical experts and a civilian air expert.
The ship originally was designed to carry 57 passengers, TWA officials said. The airline company commissioned Lockheed to build the plane two years ago.
Hughes described the trip as a “routine delivery mission” and would not say whether he would attempt to break any speed records or whether the flight would be non-stop.
“It all depends on the performance of the Connie,” he said.
The 40-ton ship, which has a cruising speed of 300 miles an hour, took off with enough gasoline for a non-stop trip. Cargo and airline planes in general use now cruise at around 180 miles an hour. Her takeoff was clocked by Larry Therkelsen, National Aeronautical Association timekeeper and official timer of the national air races before the war.
The Constellation is powered by four, 2,000-horsepower Wright air-cooled, radial engines, with 18 cylinders each, the Materiel Command said. It has three-bladed Hamilton Standard propellers and is equipped with a pressurized cabin for stratosphere flights. Its service ceiling is from 20,000 to 35,000 feet.

Lockheed C-69-LO Constellation 43-10310, c/n 049-1962, was the first production airplane. It had been flown to Las Vegas, Nevada, on the previous day, where T.W.A. personnel applied the company’s livery to the Army Air Corps-owned airplane. Flown by Lieutenant Colonel C. A. Shoup, it then returned to Burbank to prepare for the transcontinental flight.

The plan called for Howard Hughes to fly as pilot-in-command for the first half of the flight, with Captain Frye in the right seat. They would switch positions at the half-way point. Both men were experienced four-engine pilots but the Constellation was new to them. In the previous week, they had each made two training flights in the C-69, with Hughes flying 2.9 hours and Frye, 3.4.

Initially, the transport followed T.W.A.’s normal transcontinental route. It had climbed to 15,000 feet (4,572 meters) by the time it reached Kingman, Arizona. The night sky was “CAVU”—ceiling and visibility unrestricted—and there was a bright last-quarter moon shining. Passing north of Winslow, Arizona, the C-69 left the T.W.A. route and turned north to pick up a Great Circle course.
Flying over northern New Mexico, they encountered turbulence and thunderclouds. Hughes climbed to 17,500 feet (5,334 meters) to remain clear of the clouds. Light ice began forming on the airplane as they crossed over Kansas. They climbed into colder, drier air at 18,500 feet (5,639 meters).

The Constellation crossed overhead Cincinnati, Ohio, at 11:48 a.m., C.W.T. Stormy weather delayed their descent until after crossing the Ohio River.
The Constellation flew overhead National Airport at 1:54 p.m., Eastern War Time (10:54 a.m., P.W.T.). They circled overhead while traffic cleared the runway, then landed four minutes later.

The C-69’s log book showed the Burbank to overhead National Airport flight as having taken 6 hours, 56 minutes, 15 seconds.² The Aircraft Yearbook for 1945 gives the record time as “6 hours, 57 minutes and 51 seconds.” ³
Because of wartime security concerns, the Air Corps would not allow Lockheed or TWA to release specific information about the flight, other than to say that it had broken the existing transcontinental speed record. The Great Circle distance from Lockheed Air Terminal to Washington National is 2,000 nautical miles (2,302 statute miles/3,705 kilometers). Assuming that the route was flown without any deviations, the average speed of the C-69 would have been 288 knots (331 miles per hour/533 kilometers per hour).

At the time, the only airplanes which were larger than the C-69 were the prototype Douglas B-19 long range bomber and the Martin Mars flying boat. A large crowd watched the arrival of the new airplane. Dignitaries meeting the flight were General Henry H. (“Hap”) Arnold, Chief the U.S. Army Air Forces, and Secretary of Commerce Jesse H. Jones, with Oswald Ryan and Josh Lee of the Civil Aeronautics Board.

As stated above, 43-10310, c/n 1962, was the first production C-69 Constellation, following the XC-69 prototype, 43-10309, c/n 1961. It had been designed and built by the Lockheed Aircraft Corporation at Burbank, California, for Transcontinental and Western Airlines. The C-69 made its first flight in August 1943, and remained with Lockheed for manufacturer’s tests.
The Constellation was operated by a flight crew of five: two pilots, a navigator, flight engineer and radio operator. It could carry up to 81 passengers. The airplane was 95 feet, 1 3⁄16 inches (28.986 meters) long with a wingspan of 123 feet, 0 inches (37.490 meters), and overall height of 23 feet, 7⅞ inches (7.210 meters). It had an empty weight of 49,392 pounds (22,403.8 kilograms) and maximum takeoff weight of 86,250 pounds (39,122.3 kilograms).

The C-69 was powered by four air-cooled, supercharged, 3,347.662-cubic-inch-displacement (54.858 liter), Wright Aeronautical Division R3500–35 (Cyclone 18 711C18BA2) engines. Also known as the Duplex Cyclone, these were a two-row, 18-cylinder radial engines with a compression ratio of 6.85:1, which required 100/130-octane aviation gasoline. They were rated at 2,000 horsepower at 2,400 r.p.m., and 2,200 horsepower at 2,800 r.p.m. for takeoff (five minute limit), The 745C18BA2 was 6 feet, 4.26 inches (1.937 meters) long, 4 feet, 7.78 inches (1.417 meters) in diameter and weighed 2,707 pounds (1,228 kilograms). The engines drove 15 foot, 2 inch (4.623 meter) diameter, three-bladed Hamilton Standard Hydromatic 43E60 constant-speed propellers through a 0.4375:1 gear reduction. Wright produced 58 of these engines between August 1942 and October 1944.
The C-69 had a cruise speed of 313 miles per hour (504 kilometers per hour) and a range of 3,995 miles (6,429 kilometers). Its service ceiling was 25,300 feet (7,711 meters).
During the War, Lockheed Constellations were operated for the War Department by T.W.A. and Pan American Airways.
On 31 March 1947, War Assets Administration sold 43-10310 for spare parts. It was salvaged to repair other C-69 and L-049 airplanes.
In 1952, Lockheed rebuilt -310 for Inter-National Airways, Inc., which leased it to Flying Tiger Line. It was assigned civil registration NC38936.
NC38936 was destroyed by fire after landing accident during training/certification flight at Burbank, 22 January 1953.

The Los Angeles Times reported:
Fire Destroys Huge Plane on L.A. Test Hop
A rebuilt, four-engine Constellation was destroyed by fire last night seconds after it landed at Lockheed Air Terminal. Ten persons aboard the aircraft escaped without injury.
The huge craft, owned by Inter-Continental Airways, Inc., had made its second test landing for two Civil Aeronautics Authority inspectors when the main landing-gear section burst into flames which quickly spread to the fuselage and other parts of the ship, according to airport tower observers.
The plane’s landing gear apparently failed to function properly as the ship touched down and caused the plane to skid on its belly with the propellers scraping the runway, according to the observers.
Changes in Plane
The Constellation was the second in the C-69 series built by Lockheed Aircraft and during the last two years had undergone changes in construction prior to being chartered by Flying Tiger Lines from the Inter-Continental Airways, according to William Sosnow, purchasing agent for the latter company.
Burbank and Lockheed Fire Departments fought the fire and kept the flames from spreading to nearby hangars and other aircraft. Fire officials said the plane, valued at $1,000,000, was a total loss.
Final Checkout
Sosnow said the plane had received CAA partial approval Wednesday and that last night’s pilot training flight was to complete the inspection routine. It was to have flown to Oakland today for its first pay passengers, he said.
Aboard the plane, Lockheed officials said, were CAA Inspectors M.H. Griffith and Sam Chandler, Senior Pilot C.G. Fredericks, Pilots Lawrence Raab, Sheldon Eichel, August Martin and Leo Gardner; Flight Engineers Frank Lutomski and Robert R. Jackson and Radioman Morris H. Sherry.
All the crewmen were employed by Inter-Continental.
—Los Angeles Times, Vol. LXXI, Friday Morning, 23 January 1953, Part 1, Page 1, Column 3
The Bureau of Aircraft Accidents Archives, (BAAA, or B3A) data base states:
“The crew was engaged in a local test flight. On final approach, during the last segment, the crew inadvertently raised the gears. The four engine aircraft belly landed and slid for dozen yards before coming to rest in flames. While all five crew members were unhurt, the aircraft was lost.”

Squadron Leader John Dering Nettleton, V.C., Royal Air Force. (Imperial War Museum CH 5669)
Operation Margin: Just over a month after the first combat missions flown by the new Avro Lancaster B Mk.I very long range heavy bomber, Acting Squadron Squadron Leader John Dering Nettleton, RAF, commanding No. 44 (Rhodesia) Squadron, lead one of two formations of six Lancasters from RAF Waddington and RAF Woohall Spa, in Lincolnshire, England, on a very low altitude daylight penetration of enemy territory to attack the Maschinenfabrik Augsburg-Nürnberg AG (MAN) diesel engine factory at Augsburg, Bavaria, in the south of Germany. The factory was a source of diesel engines for Nazi Germany’s U-boat fleet. It was a target of high military importance, and the daylight attack was very dangerous.
Each Lancaster carried four 1,000 pound (454 kilogram) bombs. The two formations (the other was from No. 97 Squadron) crossed the English Channel at an altitude of just 50 feet (15 meters) in an effort to evade detection by enemy radar.
During the flight across France and into Germany, Nettleton’s flight was under almost constant attack by enemy fighters. Only two 44 Squadron Lancasters made it to the target and dropped their bombs, but one of those was almost immediately shot own. Only Nettleton’s bomber, Lancaster B. Mk.I R5508, KM B, survived to return to England.
The other flight, led by Squadron Leader John Sherwood, flew a different route and all six arrived at Augsburg. After bombing the factory, Sherwood’s Lancaster was hit by antiaircraft fire, caught fire, crashed and exploded. Only Sherwood survived. Another was hit but was able to drop its bombs on the target before crashing. Another Lanc was badly damaged, but dropped its bombs and made it away.
Of the twelve Lancasters that had set out, just five returned. All were damaged, one of them beyond repair.
Of the 85 airmen on the mission, 49 were listed as missing in action.
Seventeen 1,000 pound bombs had made direct hits on the factory, but only twelve detonated. Though the target suffered significant damage, production of U-boat engines continued.

John Dering Nettleton was born 28 June 1917 at Nongoma, Zululand, Union of South Africa. He was the son of John Hennah Nettleton and Ethel Maud Barker Nettleton, and the grandson of Admiral Alfred Thomas Dering Nettleton, Royal Navy. Nettleton was educated at the Western Province Preparatory School, an Anglican Church school in Claremont, a suburb of Cape Town.

While in England, Nettleton joined the Royal Air Force, and began flight training at the No. 8 Elementary and Reserve Flying Training Squadron at Reading. He was given a Short Service Commission as a Pilot Officer in the Royal Air Force, 14 December 1938 ¹ and reported to No. 12 FTS at RAF Grantham in Lincolnshire, but within two weeks was reassigned to No. 11 FTS at RAF Shawbury, in Shropshire. He graduated 22 July 1939.
Nettleton was appointed an Acting Pilot Officer (41452) on probation, with effect 3 September 1939—the same day that the United Kingdom and France declared war on Germany, following that country’s invasion of Poland.² He was assigned to No. 207 Squadron, an operational training unit for the Fairey Battle, a single-engine light bomber powered by a Rolls-Royce Merlin engine, based at RAF Cottesmore in the East Midlands of England.

Avro Lancaster B Mk.I R5727 over Montreal, Canada, 1942. (Royal Air Force)
The Avro Lancaster made its first flight 9 January 1941, and flew its first combat mission (with No. 44 Squadron) on 3 March 1942. The Lancaster B Mk.I was operated by a crew of seven: pilot, flight engineer, navigator/bombardier, radio operator and three gunners. It was a large, all-metal, mid-wing monoplane with retractable landing gear. It was 68 feet, 11 inches (21.001 meters) long with a wingspan of 102 feet, 0 inches (31.090) meters and an overall height of 19 feet, 6 inches (5.944 meters). The Mk.I had an empty weight of 36,900 pounds (16,738 kilograms) and its maximum takeoff weight was 68,000 pounds (30,909 kilograms)
Early production Lancasters were equipped with four liquid-cooled, supercharged, 1,648.96-cubic-inch-displacement (27.01 liter), Roll-Royce Merlin XX single overhead camshaft (SOHC) 60° V-12 engines, which were rated at 1,480 horsepower at 3,000 r.p.m. to 6,000 feet (1,829 meters). The Merlins drove three-bladed, 13 feet, 0 inch (3.962 meters), de Havilland Hydromatic quick-feathering, constant-speed airscrews (propellers), through a 0.420:1 gear reduction.
The Mark I had a maximum economic cruise speed of 267 miles per hour (430 kilometers per hour) at 20,800 feet (6,340 meters), and a maximum speed of 286 miles per hour (460 kilometers per hour) at 20,000 feet (6,096 meters) at a gross weight of 45,300 pounds (20,548 kilograms). Its service ceiling was 20,000 feet (6,096 meters) at 64,500 pounds (29,257 kilograms). It had a range of 2,530 miles (4,072 kilometers) with a 7,000 pound (3,175 kilogram) bomb load.
The Lancaster was designed to carry a 14,000 pound (6,350 kilogram) bomb load, but modified bombers carried the 22,000 pound (9,979 kilogram) Grand Slam bomb.
For defense, the standard Lancaster had eight Browning .303-caliber Mark II machine guns in three power-operated turrets, with a total of 14,000 rounds of ammunition.
According to the Royal Air Force, “Almost half all Lancasters delivered during the war (3,345 of 7,373) were lost on operations with the loss of over 21,000 crew members.”
Only two airworthy Avro Lancasters are in existence.

Igor Sikorsky piloting his pontoon-equipped VS-300, 17 April 1941. (Sikorsky Historical Archives)
17 April 1941: Igor Sikorsky’s Vought-Sikorsky VS-300 helicopter went through various rotor configurations during development as he searched for a combination that would give stability, anti-torque control, as well as lateral and yaw control. By April 1941, the VS-300 was configured with a single main rotor for lift and three smaller tail rotors to provide anti-torque and directional control.
This was not the ultimate solution, but he had the aircraft fitted with three inflatable pontoons and on 17 April, made a successful water landing, demonstrating that the helicopter could be a practical amphibious aircraft. During a lecture to the Rotating Wing Section of the Tenth Annual Meeting of the Institute of Aeronautical Sciences, Igor Sikorsky gave a brief description of the flight:
Igor Ivanovich Sikorsky (Sikorsky Archives)
“On April 17 the helicopter, mounted on rubber floats, was repeatedly taken off from water and landed on water and then landed on ground, demonstrating for the first time a direct lift aircraft with excellent amphibian characteristics on which no adjustments whatsoever are needed when going from water to land and vice versa.”
The VS-300 had a welded tubular steel airframe and used a 28-foot (5.34 meters) diameter, fully-articulated, three-bladed main rotor, which turned clockwise (as seen from above) at 260 r.p.m. (The advancing blade was on the left. This would later be reversed.) The main rotor had collective pitch control for vertical control, but cyclic pitch (Sikorsky referred to this as “sectional control”) for directional control would not be developed for another several months.
The tail “propellers” (what we now consider to be rotors—one vertical and two horizontal) each had two blades with a diameter of 7 feet, 8 inches (2.337 meters) and turned approximately 1,300 r.p.m. The vertical rotor provided “torque compensation” (anti-torque) and the blade pitch was fully reversible. The horizontal rotors were mounted on 10-foot (3.048 meters) outriggers at the aft end of the fuselage. For lateral control, the pitch on one rotor was increased and the other decreased. For longitudinal control, the pitch of both rotors was increased or decreased together.

The VS-300 was originally equipped with an air-cooled, normally-aspirated 144.489-cubic-inch-displacement (2.368 liter) Lycoming O-145C-3 four-cylinder horizontally-opposed engine which was rated at 75 horsepower at 3,100 r.p.m. According to Mr. Sikorsky, “early in 1941,” the Lycoming engine was replaced by an air-cooled, normally-aspirated 198.608 cubic inch (3.255 liter) Franklin 4AC-199-E, a four-cylinder horizontally-opposed overhead valve (OHV) direct-drive engine with a compression ratio of 7:1, rated at 90 horsepower at 2,500 r.p.m. It is not known if this change was made prior to 17 April.
19 March–17 April 1964: Geraldine Fredritz (“Jerrie”) Mock landed her 1953 Cessna 180, Spirit of Columbus, N1538C, at Columbus, Ohio, completing a circumnavigation of the Earth she had begun at 9:31 a.m., 19 March 1964. Mock was the first woman to complete a circumnavigation by air.¹ Her journey covered 23,103 miles (36,964 kilometers). The total elapsed time was 29 days, 11 hours, 59 minutes. The flight set a Fédération Aéronautique Internationale (FAI) World Record for Speed Around the World, Eastbound, of 52.75 kilometers per hour (32.78 miles per hour).²
Cessna 180 serial number 30238 was built by the Cessna Aircraft Company, Inc., Wichita, Kansas, in 1953, and registered N1538C, the first year of production for the model. It was the 238th of 640 Model 180s that were built during the first year of production. 6,193 were built by the time production came to an end in 1986. N1538C was purchased for Jerrie Mock in 1963, with a total of 990 hours on the engine and airframe. The passenger seats were removed and replaced with additional fuel tanks. Additional radios and instruments were installed.
The Cessna Model 180 is an all-metal, four-place, single-engine, high-wing monoplane with fixed landing gear. It is 25 feet, 6 inches (7.772 meters) long with a wingspan of 36 feet, 2 inches (11.024 meters) and height of 7 feet, 6 inches (2.286 meters). If the optional rotating beacon is installed, the height is increased to 7 feet, 9 inches (2.362 meters). The Cessna 180 has an approximate empty weight of 1,525 pounds (692 kilograms), depending on installed equipment, and the maximum gross weight is 2,800 pounds (1,270 kilograms).
Spirit of Columbus is powered by an air-cooled, normally-aspirated 471.239-cubic-inch-displacement (7.722 liter) Continental O-470-A horizontally-opposed six-cylinder overhead valve (OHV) direct-drive engine with a compression ratio of 7:1. This engine is rated at 225 horsepower at 2,600 r.p.m., burning 80/87 aviation gasoline, and turns a two-bladed constant speed propellerwith a diameter of 6 feet, 10 inches (2.083 meters).
Miss Fredritz married Russell Charles Mock, 21 March 1945, in Cook County, Illinois. They would have three children, Valerie, Roger and Gary.
