18 April 1942: Task Force 16, under the command of Vice Admiral William F. Halsey, Jr., U.S. Navy, approached the Japanese islands on a daring top secret joint Army-Navy attack.

Planning for the attack began in January 1942 under orders from Admiral Earnest J. King, Commander-in-Chief United States Fleet. Captain Donald B. Duncan, U.S. Navy, was responsible for the plan.

The operation was carried out by Task Force 16 under the command of Vice Admiral William F. Halsey, Jr., United States Navy. Task Force 16 consisted of two aircraft carriers, USS Enterprise (CV-6) and USS Hornet (CV-8), four cruisers, eight destroyers and two oilers. There were two air groups, consisting of eight squadrons of 54 fighters, 72 dive bombers, 36 torpedo bombers, and one squadron of of 16 medium bombers. Lieutenant Colonel James Harold (“Jimmy”) Doolittle, U.S. Army Air Corps, commanded the Strike Group of North American Aviation B-25 Mitchell bombers aboard Hornet.

With the land-based Army bombers secured to Hornet‘s flight deck, her own fighters had been struck below. The air group from Enterprise provided Combat Air Patrol for the task force. The plan was to bring the B-25s within 400 miles (645 kilometers) of Japan, have them take off and carry out the attack, then fly on to airfields in Chinese territory.

At 0500 hours, the task force was sighted by a Japanese picket boat while still over 700 miles (1,127 kilometers) away from Tokyo. At 0644 another vessel was spotted by the task force. Fearing that surprise had been lost, Admiral Halsey ordered the bombers launched while still 623 miles (1,003 kilometers) from land.

The sixteen B-25s were successfully launched from Hornet and headed for their assigned targets. The lead airplane, B-25B serial number 40-2344, was flown by Lieutenant Colonel Doolittle.

Single B-25s attacked targets in the cities of Tokyo, Nagoya, Osaka and Kobe.The first bombs were dropped on Tokyo at 1215 local time. This was the first offensive operation carried out by the United States of American against the Empire of Japan during World War II.

The actual destructive effect of the attack was minimal. It had been hoped that there would be psychological effects on the citizenry, however the arrival of the American bombers coincided with an ongoing air raid drill, and many thought it was all part of the drill.

Militarily, however, the attack was a stunning success. Four Japanese fighter groups, needed elsewhere, were pinned down at home, waiting for the next attack.

Not a single B-25 was lost over Japan. One landed in Vladivostok where the crew and airplane were interred by the “neutral” Soviets, but they eventually were able to get home. The rest continued on toward China, though without enough fuel to reach their planned destinations. Four B-25s made crash landings, but the crews of the others bailed out into darkness as their planes ran out of gas.

With their spacecraft crippled by an internal explosion on 13 April, the planned lunar landing mission had to be aborted. Astronauts James A. Lovell, Jr., John L. Swigert, Fred W. Haise, Jr., worked continuously with engineers at Mission Control, Houston, Texas, to overcome a series of crises that threatened their lives.

17 April 1970: Because of the unusual configuration of the Apollo 13 Command Module, Service Module and Lunar Module “stack” during the coast from the Moon back to Earth, an additional, unplanned, Mid-Course Correction burn, MCC-7, had to be carried out. The damage to the Service Module prevented the use of its 21,900 pounds thrust (97.42 kilonewtons) Aerojet General Service Propulsion System engine. It was necessary to use the LM’s Space Technology Laboratories (TRW) VTR-10 Descent Propulsion System engine. The DPS engine produced 10,500 pounds of thrust (46.71 kilonewtons). The maneuver had to be carried out manually by the astronauts from the LM’s cockpit.

Mission Commander Lovell visually aligned the spacecraft with the LM’s Reaction Control System thrusters, by sighting the Earth in his window of the LM. Once aligned, LM pilot Fred Haise conducted the burn, which was timed by CM pilot Jack Swigert.

Swigert timed the burn using his NASA-issued Omega Speedmaster Professional Chronograph, a very accurate manual wristwatch.

The Mid Course Correction ignition commenced at T+137:39:51.5 and the engine was cutoff at T+137:40:13.0 (12:52:51–12:53.13 UTC), for a duration of 21.5 seconds.

MCC-7 was performed at EI-5 hours (137:39 GET). The same manual piloting technique used for MCC-5 was used for control during MCC-7. This was manual crew pitch and roll control with the TTCA and automatic yaw control by the AGS. MCC-7 was performed with LM RCS using the +X translation push button. It steepened the flight path angle at EI to -6.49 degrees. After MCC-7, the crew maneuvered the spacecraft to the SM separation attitude. The CM re-entry RCS system was activated and a firing test of the thrusters was successful.

Omega Speedmaster Professional “Moon Watch.” (Omega)

The Omega Speedmaster Professional Chronograph is a manual-winding analog wrist watch produced by Omega, a luxury brand of Société Suisse pour l’Industrie Horlogère, (SSIH) and now a part of the SWATCH Group. The case is made of stainless steel and has a diameter of 48 millimeters (1.89 inches). The Speedmaster Professional, which is also known as the “Moon Watch,” or “Speedy” to watch collectors, features a stop watch function and three sub dials for recording hours, minutes and seconds. The chronograph has a black dial with tritium-painted hands and hour marks. The bezel has a tachymeter for calculating speed based on time. When fully wound, the Speedmaster can run for up to 48 hours. The chronograph is water resistant to a depth of 50 meters (164 feet).

The Speedmaster’s crystal is not glass, but “hesalite,” a clear, scratch-resistant plastic. There had been concern that if a crystal broke during a space flight, glass fragments could be scattered throughout the weightless environment of the spacecraft, presenting a danger to the astronauts.

NASA provided Omega Speedmaster Professional Chronographs to Gemini and Apollo Program astronauts. Each watch was engraved with NASA’s two-digit serial number, and could be equipped with an adjustable length Velcro strap which allowed the watch to be worn on the outside of the space suit. NASA also assigned an equipment part number.

Jack Swigert’s watch, p/n SEB12100039-002, was NASA’s number 69. It is in the collection of the Smithsonian Institution National Air and Space Museum, as Catalog Number 1977-1181.000. In 2016, the watch was on display at the University of Colorado.

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).

The airplane has a cruise speed of 162 miles per hour (261 kilometers per hour) at 6,500 feet (1,981 meters), and its maximum speed is 170 miles per hour (274 kilometers per hour) at Sea Level. Its service ceiling is 19,600 feet (5,974 meters). The Cessna 180 has a maximum fuel capacity of 84 gallons (318 liters), giving it an optimum range of 1,215 miles (1,955 kilometers) at 10,000 feet (3,048 meters) and 121 miles per hour (195 kilometers per hour).

After her around the world flight, Jerrie Mock never flew Spirit of Columbus again. Cessna exchanged it for a new six-place P206 Super Skylane, N155JM. For many years N1538C was hanging over a production line at the Cessna factory. Today, Mock’s Cessna 180 is on display at the Steven F. Udvar-Hazy Center, Smithsonian Institution National Air and Space Museum.

Geraldine Lois Fredritz was born 22 November 1925 at Newark, Ohio. She was the first of three daughters of Timothy J. Fredritz, a clerk for a power company, and Blanche M. Wright Fredritz. Jerrie Fredritz graduated from Newark High School in 1943, then studied aeronautical engineering at Ohio State University, Columbus, Ohio. She was a member of the Phi Mu (ΦΜ) sorority.

Miss Fredritz married Russell Charles Mock, 21 March 1945, in Cook County, Illinois. They would have three children, Valerie, Roger and Gary.

Jerrie Mock wrote about her around-the-world flight in Three Eight Charlie, published by Lippincott, Philadelphia, Pennsylvania, 1970.

Geraldine Fredritz Mock died at Qunicy, Florida, Monday, 30 September 2014, at the age of 88 years. She had requested that her ashes be spread over the Gulf of Mexico.
