Spirit of St. Louis over San Diego, May 1927. (San Diego Air and Space Museum)
4 May 1927: Charles A. Lindbergh completes his last series of flight tests of the Ryan NYP, N-X-211, Spirit of St. Louis. Flying at 50 feet (15.2 meters) over San Diego Bay, he times the Spirit‘s flight from marker to marker with a stop watch. The airspeed indicator jumps past 130 miles per hour (209.2 kilometers per hour). He records indicated air speed and engine r.p.m. at various power settings. At 1,500 r.p.m. the Spirit can fly at 96 miles per hour (154.5 kilometers per hour). He makes three runs in each direction to come up with averages.
After the speed runs, Lindbergh flies back to Camp Kearney for load tests. Take-off distances are measured while increasing the fuel load in 50 gallon (189.3 liter) increments.
“Twilight is thickening. We stake the Spirit of St. Louis down and leave it under guard. . . When I get back to the city, I telegraph my partners that the tests are satisfactorily completed. . . .”
—The Spirit of St. Louis, by Charles A. Lindbergh, Charles Scribner’s Sons, 1953, Chapter 37 at Page 128.

Following its first flight from Dutch Flats on 28 April 1927, Charles A. Lindbergh continued flight testing of the new Ryan NYP, N-X-211, Spirit of St. Louis, over the following week from the Camp Kearney parade grounds (now known as Kearney Mesa) near San Diego, California.
Data was gathered for takeoff and landing distances, obstacle clearance, power settings, fuel consumption, rates of climb, air speeds, speeds over a measured distance, instrument calibrations. . . All the things that need to be known so that reliable planning for a transcontinental and transoceanic flight could be carried out.
In his book, The Spirit of St. Louis, (Charles Scribner’s and Sons, 1953) Lindbergh wrote about having a gust of wind blow his clipboard containing the carefully collected data out the Spirit‘s window, and his efforts to recover it, which he did.

“This morning I’m going to test the Spirit of St. Louis. It’s the 28th of April — just over two months since I placed our order with the Ryan Company. . . Today, reality will check the claims of formula and theory on a scale which hope can’t stretch a single hair. Today, the reputation of the designing engineer, of the mechanics, in fact of every man who’s had a hand in building the Spirit of St. Louis, is at stake. And I’m on trial too, for quick action on my part may counteract an error by someone else, or a faulty move may bring a washout crash.“

The Ryan NYP, registration N-X-211, has been towed from the Ryan Airlines Company factory in San Diego, California, to nearby Dutch Flats for its first test flight. Air Mail pilot Charles A. Lindbergh, representing a syndicate of St. Louis businessmen, has contracted with Ryan to build a single-engine monoplane designed for one man to fly non-stop across the Atlantic Ocean, from New York to Paris.
“I signal chocks away. . . and open the throttle. . . I’ve never felt an airplane accelerate so fast before. The tires are off the ground before they roll a hundred yards. . . .”
And the rest is History.

12 April 1972: Famed pioneer aviator Charles A. Lindbergh, Brigadier General, United States Air Force Reserve, with a television news team investigating reports of a “lost tribe” in the Tasaday mountains of Mindanao, Republic of the Philippines, were stranded on a 3,000-foot (915 meter) jungle ridge line when their support helicopter developed mechanical trouble. Faced with a three-day walk through difficult terrain, the 70-year-old pilot was in trouble. The 31st Aerospace Rescue and Recovery Squadron at Clark Air Base on the Island of Luzon, was called in.
Major Bruce Ware and his crew, co-pilot Lieutenant Colonel Dick Smith, flight engineer Staff Sergeant Bob Baldwin, and pararescueman Airman 1st Class Kim Robinson, flew their Sikorsky HH-3E Jolly Green Giant, 66-13289, over 600 miles (965 kilometers) to the rescue location. The helicopter, call sign “Jolly 36,” was supported by a Lockheed HC-130N Combat King for aerial refueling, navigation and communications.

The pick-up point was a knife-edge ridge. Trees had been cut for clearance, but landing the Sikorsky was impossible. Major Gray had to hover with the nose wheel on one side of the ridge, and the main wheels on the other, with the boarding steps a few feet over the ridge top. The very high temperature and humidity created a density altitude equivalent to more than 6,000 feet (1,830 meters). Hovering the helicopter out of ground effect (OGE) was difficult under these conditions and fuel had to be dumped to lighten the load. Even so, only a few persons could be carried at a time. Eight trips to a drop point 15 minutes away were required. Lindbergh was on the second load. On clearing the ridge, Major Ware rendezvoused with the HC-130N to take on fuel. They partially refueled twice during the ridge line operation. Lindbergh commented that although he had helped to develop inflight refueling, he had never been aboard an aircraft while it was taking place.
After all persons—a total of 46—had been removed from the mountain, Jolly 36 and the Combat King flew back to Clark Air Base. The total elapsed time for the mission was 12 hours, 20 minutes, with 11 hours, 30 minutes actual flight time. Major Ware had to just sit in the cockpit for a few minutes before he could leave the helicopter, but General Lindbergh refused to leave until Ware was ready.
Distinguished Flying Cross
Major Ware was awarded the Distinguished Flying Cross. The other crew members of Jolly 36 and all those aboard the Combat King received the Air Medal. Ware retired from the Air Force in July 1989, after 29 years of service.
Sikorsky HH-3E 66-13289 (c/n 61-588) was delivered to the U.S. Air Force 8 December 1967 as a CH-3E. By July it was in South East Asia, operating as Jolly Green 03. The helicopter was later modified to the HH-3E combat rescue configuration. It was lost in the South China Sea in 1972, following a rescue from a freighter west of Luzon, Philippine Islands.
Notified by the accompanying HC-130 that the helicopter was trailing smoke, the aircraft commander, Lieutenant Colonel James (“Bud”) Green, made an emergency landing at sea. It was determined that the main transmission had cracked and was leaking oil.
A U.S. Navy helicopter hoisted the Air Force crew and the rescued man aboard, while a tug boat had been dispatched to recover 66-13289. Unfortunately the Jolly Green Giant overturned during a squall and sank in 12,900 feet (3,932 meters) of water.

28 March 1935: Near Roswell, New Mexico, Robert H. Goddard successfully launched the first gyroscopically-stabilized liquid-fueled rocket. In a 20-second flight, the A Series rocket, number A-5, reached an altitude of 4,800 feet (1,463 meters) and traveled 13,000 feet (3,962 meters) down range. Its speed was 550 miles per hour (885 kilometers per hour). During the flight, the rocket corrected its flight path several times.
“Dr. Robert H. Goddard observes the launch site from his launch control shack while standing by the firing control panel. From here he can fire, release, or stop testing if firing was unsatisfactory. Firing, releasing, and stop keys are shown on panel. The rocket is situated in the launch tower.” (U.S. Air Force)Goddard A-series rocket. (Clark University)
The A Series rockets were of varying lengths and mass. The representative A-series rocket displayed at the National Air and Space Museum is 15 feet, 4½ inches (468.63 centimeters) long with a diameter of 9 inches (22.86 centimeters). The span across the fins is 1 foot, 9½ inches (54.61 centimeters). It weighs 78.5 pounds (35.6 kilograms). The rocket was fueled with gasoline and liquid oxygen, pressurized with nitrogen.
A gyroscope controlled vanes placed in the engine’s exhaust, providing stabilization during powered flight.
Goddard flew the A-series 14 times between 15 January and 29 October 1935.
The National Air and Space Museum describes the rocket’s construction:
“Aluminum skin, thin gauge, a long tail section from bottom of fins to bottom of mid-section. Aluminum skin also on parachute section and nosecone wholly of spun aluminum except for steel attachment screw. Steel skin (for greater strength and insulation) below nosecone, over mid-section (over propellant tanks), and around small section above fins. One steel tube or pipe on each side of rocket, along propellant section; one smaller diameter copper tube on one side. Steel nozzle and other interior components. Fabric parachute.”
Goddard is the “Father of Modern Rocketry.” Many of his developments were copied by German engineers as they developed the V2 rocket of World War II. And this led to America’s own post-War rocket developments, including the mighty Saturn V moon rocket.
