5 February 1971, 09:18:11 UTC, T + 108:15:09.30: The Apollo 14 Lunar Module Antares (LM-8), with astronauts Alan B. Shepard and Edgar D. Mitchell aboard, landed at the Fra Mauro Highlands, The Moon.
This was the third manned lunar landing. It was 9 years, 8 months, 30 days, 18 hours, 43 minutes, 58 seconds since Shepard had lifted off from Cape Canaveral aboard Freedom 7, becoming the first American astronaut launched into space.
5 hours, 36 minutes later, at 14:54 UTC, T + 113:51, Alan Shepard stepped on to the surface of The Moon.

31 January 1971, 04:03:02 a.m., Eastern Standard Time: Apollo 14 (AS-509) lifted off for The Moon from Space Flight Launch Complex 39A, Kennedy Space Center, Cape Canaveral, Florida. The Mission Commander was Captain Alan Bartlett Shepard, Jr., United States Navy. The Command Module Pilot was Colonel Stuart Allen Roosa, United States Air Force, and the Lunar Module Pilot was Captain Edgar Dean Mitchell, Sc.D., United States Navy. Their destination was the Fra Mauro Highlands.
Apollo 14 was the eighth manned mission of the Apollo Program, and the third to land on the surface of the moon.
Alan Shepard was the first American astronaut. He flew into space aboard a Mercury spacecraft, Freedom 7, launched from Cape Canaveral by a Redstone rocket, 5 May 1961.

Mitchell and Roosa had not flown in space before. This would be their only space flight.
The Apollo Command/Service Module was built by the Space and Information Systems Division of North American Aviation, Inc., at Downey, California.
The SPS engine was an AJ10-137, built by Aerojet General Corporation of Azusa, California. It burned a hypergolic fuel combination of Aerozine 50 and nitrogen tetraoxide, producing 20,500 pounds of thrust (91.19 kilonewtons). It was designed for a 750 second burn, or 50 restarts during a flight.
The Saturn V rocket was a three-stage, liquid-fueled heavy launch vehicle. Fully assembled with the Apollo Command and Service Module, it stood 363 feet (110.642 meters) tall. The first and second stages were 33 feet (10.058 meters) in diameter. Fully loaded and fueled the rocket weighed 6,200,000 pounds (2,948,350 kilograms). It could lift a payload of 260,000 pounds (117,934 kilograms) to Low Earth Orbit.
The first stage was designated S-IC. It was designed to lift the entire rocket to an altitude of 220,000 feet (67,056 meters) and accelerate to a speed of more than 5,100 miles per hour (8,280 kilometers per hour). The S-IC stage was built by Boeing at the Michoud Assembly Facility, New Orleans, Louisiana. It was 138 feet (42.062 meters) tall and had an empty weight of 290,000 pounds (131,542 kilograms). Fully fueled with 203,400 gallons (770,000 liters) of RP-1 and 318,065 gallons (1,204,000 liters) of liquid oxygen, the stage weighed 5,100,000 pounds (2,131,322 kilograms). It was propelled by five Rocketdyne F-1 engines, producing 1,522,000 pounds of thrust (6770.19 kilonewtons), each, for a total of 7,610,000 pounds of thrust at Sea Level (33,850.97 kilonewtons). These engines were ignited seven seconds prior to lift off and the outer four burned for 168 seconds. The center engine was shut down after 142 seconds to reduce the rate of acceleration. The F-1 engines were built by the Rocketdyne Division of North American Aviation at Canoga Park, California.
The S-II second stage was built by North American Aviation at Seal Beach, California. It was 81 feet, 7 inches (24.87 meters) tall and had the same diameter as the first stage. The second stage weighed 80,000 pounds (36,000 kilograms) empty and 1,060,000 pounds loaded. The propellant for the S-II was liquid hydrogen and liquid oxygen. The stage was powered by five Rocketdyne J-2 engines, also built at Canoga Park. Each engine produced 232,250 pounds of thrust (1,022.01 kilonewtons), and combined, 1,161,250 pounds of thrust (717.28 kilonewtons).

The Saturn V third stage was designated S-IVB. It was built by Douglas Aircraft Company at Huntington Beach, California. The S-IVB was 58 feet, 7 inches (17.86 meters) tall with a diameter of 21 feet, 8 inches (6.604 meters). It had a dry weight of 23,000 pounds (10,000 kilograms) and fully fueled weighed 262,000 pounds. The third stage had one J-2 engine and also used liquid hydrogen and liquid oxygen for propellant. The S-IVB would place the Command and Service Module into Low Earth Orbit, then, when all was ready, the J-2 would be restarted for the Trans Lunar Injection.
Eighteen Saturn V rockets were built. They were the most powerful machines ever built by man.

27 January 1967: During a “plugs out” test of the Apollo 1 Command Module, two weeks ahead of the scheduled launch of the Apollo/Saturn 1B AS-204—the first manned Apollo Program space flight—a fire broke out in the pressurized pure oxygen environment of the capsule and rapidly involved the entire interior.
The pressure rapidly built to 29 pounds per square inch (200 kPa) and 17 seconds later, at 23:31:19.4 UTC, the capsule ruptured.
The three astronauts, Lieutenant Colonel Virgil I. Grissom, United States Air Force, Lieutenant Colonel Edward H. White II, United States Air Force, and Lieutenant Commander Roger B. Chaffee, United States Navy, were killed.
AD ASTRA PER ASPERA
NASA has a detailed summary of the accident and investigation at:
Captain Eugene A. Cernan, U.S.N., in the cockpit of NASA 947, a Bell 47G-3B-1, as it hovers in ground effect, circa 1970. (NASA)Eugene A. Cernan, backup commander, Apollo 14. (NASA)
23 January 1971: NASA Astronaut Eugene Andrew (“Gene”) Cernan, backup commander for Apollo 14, was flying NASA 947, a 1967 Bell Model 47G-3B-1 helicopter, (N947NA, serial number 6665), on a proficiency flight. He intended to practice vertical approaches as a warmup for a lunar landing.
With full fuel tanks, NASA 947 was heavy. Cernan decided to burn off some fuel by flying along the Indian River before the vertical approaches:
“That gave me a reason to loaf around the sky for a while and invest the extra fuel in some fun flying.
“Small boats dotted the clear water below and bright islands mounded here and there on the river. Hardly a ripple disturbed the mirrorlike surface. After so many months of hard work and concentration, I couldn’t resist the temptation for a bit of mischief known among pilots as ‘flat-hatting.’ So I nosed over and swooped down from a couple of hundred feet to dance the chopper around island beaches and among the boaters, steadily getting closer to the surface. . .
“Without realizing the danger, I flew into a trap that was the plague of seaplane pilots. Without ripples, the water provided no depth perception and my eyes looked straight through the clear surface to the reflective river bottom. I had lost sight of the water. But I was in control, or at least I thought so. . . until the toe of my left skid dug into the Indian River.
“. . . I twisted the collective with my left hand and applied more power, pulling back on the controls, trying to get the machine to climb out of trouble. A plume of water erupted beneath the skid, then the canopy struck and a rushing tidal wave filled my vision as the helicopter lost any semblance of aerodynamic design. In a single flashing instant, it went from a speed of 100 knots to flat zero with a lurch as severe as any I had ever felt landing on an aircraft carrier or staging in a spacecraft. I crashed with a spectacular explosion.”

The Bell 47 was torn apart by the impact. The cabin section, with Cernan still strapped inside, sank to the bottom of the river. As a Naval Aviator, he was trained in under water egress. He freed himself from the wreck and made his way to the surface. Gasoline from the ruptured fuel tanks was floating on the water and had caught fire. Cernan suffered some minor burns, but was otherwise unhurt. He was rescued by fishermen who were nearby.
The location of the crash was in the Indian River near Malabar, Florida.
An accident investigation board, led by Astronaut James A. Lovell, commander of Apollo 13, concluded that the accident was pilot error, in that Cernan had misjudged his altitude when flying over the water.
Colonel James A. McDivitt
A week after the flight crew for Apollo 17 was announced, in a meeting with Dr. Robert R. (“Bob”) Bob Gilruth, Director of the Manned Spacecraft Center, and Christopher C. Kraft, Jr., Deputy Director of MSC and Director of Flight Operations, Colonel James Alton McDivitt, U.S. Air Force, NASA’s Manager of the Apollo Spacecraft Program (and who had commanded Gemini 4 and Apollo 9), insisted that Gene Cernan be grounded for poor judgement and not assigned as commander of Apollo 17.
Chris Kraft wrote:
“Why didn’t you ask me about this crew?” he [McDivitt] demanded. “Cernan’s not worthy of this assignment, he doesn’t deserve it, he’s not a very good pilot, he’s liable to screw everything up, and I don’t want him to fly.
I was shocked at how strongly Jim was reacting. “Why didn’t you ask me” he pleaded. “Why didn’t you ask me?” Then he shocked me further. “If you don’t get rid of him, I’ll quit.”
. . . I called McDivitt and told him that Cernan was staying. . .
“Thank you,” he said. “You’ll have my resignation shortly.”

The Bell Model 47, designed by Arthur M. Young of the Bell Aircraft Corporation, Buffalo, New York, was the first helicopter to receive civil certification from the Civil Aviation Administration, predecessor of the Federal Aviation Administration. On 8 March 1946, the aircraft received C.A.A. Type Certificate H-1.
The Bell 47G was the first helicopter manufactured by the Bell Aircraft Corporation at the company’s new plant at Fort Worth, Texas. It was also produced under license by Agusta, Kawasaki and Westland.

The Bell Model 47G-3B-1 was issued Type Certificate 2H-3 on 25 January 1963. It is a 3-place, single-engine light helicopter, operated by a single pilot. The helicopter has dual flight controls and can be flown from either the left or right. The airframe is constructed of a welded tubular steel framework with a sheet metal cockpit. The landing gear consists of two lateral, horizontal tubular cross tubes, and two longitudinal “skids,” curved upward at the front. Ground handling wheels can be attached to the skids. The most distinctive feature of the Bell 47 is the large plexiglass “bubble” canopy. The main rotor flight controls use a system of bell cranks and push-pull tubes. The cyclic and collective are hydraulically boosted. The tail rotor is controlled by pedals and stainless steel cables.

With rotors turning, the Bell 47G-3B-1 has an overall length of 43 feet, 5.55 inches (13.247 meters). From the forward tip of the skids to the aft end of the tail rotor guard, the fuselage is 32 feet, 7.40 inches long (9.942 meters). The main rotor has a diameter of 37 feet, 0.50 inches (11.290 meters). The tail rotor diameter is 5 feet, 10.1 inches (1.781 meters). Height to top of main rotor mast is 9 feet, 3.7 inches (2.837 meters).
The Bell 47G-3B-1 has an empty weight of approximately 1,820 pounds (826 kilograms), depending on installed equipment. Its maximum gross weight is 2,950 pounds (1,338 kilograms).
The main rotor, in common to all American-designed helicopters, rotates counter-clockwise as seen from above. (The advancing blade is on the helicopter’s right.) The anti-torque (tail) rotor is mounted to the right side of an angled tail boom extension, in a tractor configuration, and rotates counter-clockwise as seen from the helicopter’s left. (The advancing blade is above the axis of rotation.)
The main rotor is a two-bladed, under-slung, semi-rigid assembly that would be a characteristic of helicopters built by Bell for decades. The main rotor system incorporates a stabilizer bar, positioned below and at right angles to the main rotor blades. Teardrop-shaped weights are placed at each end of the bar, on 100-inch (2.540 meters) centers. The outside diameter of the stabilizer bar is 8 feet, 6.8 inches (2.611 meters). The pilot’s inputs to the cyclic stick are damped through a series of mechanical linkages and hydraulic dampers before arriving at the pitch horns on the rotor hub. The result is smoother, more stable flight, especially while at a hover. The stabilizer bar action is commonly explained as being “gyroscopic,” but this is incorrect. (A similar system is used on the larger Bell 204/205/212 helicopters.)
The Bell 47G-3B-1 used tip-weighted high-inertia metal main rotor blades. The airfoil is symmetrical, using the NACA 0015 profile. The operating range of the main rotor is 322–370 r.p.m.
The working parts of this Agusta-Bell 47G-3B-1 are clearly visible in this photograph. (M. Bazzani/Heli-Archive)
The 47G-3B-1 used an AVCO Lycoming TVO-435-B1A, -B1B, -D1A, or -D1B engine. The TVO-435 is an air-cooled, turbosupercharged 433.976-cubic-inch-displacement (7.112 liter) vertically-opposed, six-cylinder overhead-valve engine with a compression ratio of 7.30:1. It is equipped with a Garrett AiResearch T-1108 turbosupercharger, which provides a constant manifold pressure with decreasing pressure altitude. The engine idles at 1,500 r.p.m. Its normal operating range is 3,000 to 3,200 r.p.m. (3,100–3,200 r.p.m., above 10,000 feet, or 3,048 meters). The TVO-435-B1 has a maximum continuous power rating of 220 horsepower at 3,200 r.p.m., with a manifold pressure of 27.5 inches Hg (0.931 Bar); and a maximum 270 horsepower at 3,200 r.p.m. at 32.8 inches Hg (1.111 Bar) (-B1) or 32.0 inches (1.084 Bar) (-D1) at Sea Level, for takeoff (5-minute limit).
The TVO-435 is 34.73 Inches (0.882 meters) high, 33.58 inches (0.878 meters) wide and 24.13 inches (0.613 meters) deep, and weighs 464.00 pounds (178.26 kilograms) to 481.00 pounds (182.89 kilograms), depending of the specific engine variant.
Engine torque is sent through a centrifugal clutch to a gear-reduction transmission, which drives the main rotor through a two-stage planetary gear system. The transmission also drives the tail rotor drive shaft, and through a vee-belt/pulley system, a large fan on the forward face of the engine to provide cooling air.

The Bell 47G-3B1 has a maximum cruise speed of 80 miles per hour (129 kilometers per hour) from 1,000 to 4,500 feet (305–1,372 meters). This decreases to 70 miles per hour up to 10,000 feet (3,048 meters), and 50–60 miles per hour (80–97 kilometers per hour) up to 15,000 feet (4,572 meters). The helicopter’s maximum speed (VNE) is 105 miles per hour (169 kilometers per hour) from Sea Level to 4,500 feet (1,372 meters). Above that altitude, VNE is reduced 7 miles per hour (11.3 kilometers per hour) for every 1,000 foot (305 meters) increase in altitude. Above 15,000 feet, the VNE continues to decrease at 5 miles per hour (8 kilometers per hour) per 1,000 feet (305 meters).
The Bell 47G-3B-1 demonstrated the ability to over in ground effect (HIGE) at a gross weight of 2,850 pounds (1,293 kilograms) at the summit of Pike’s Peak, 14,115 feet (4,302 meters), in the Rocky Mountains of Colorado. The Density Altitude was approximately 15,000 feet (4,572 meters). At the same gross weight, it hovered out of ground effect (HOGE) at 9,000 feet (2,743 meters), Density Altitude. The helicopter has a maximum altitude limitation of 20,000 feet (6,096 meters).
Fuel is carried in two gravity-feed tanks, mounted above and on each side of the engine. The total fuel capacity is 61.6 gallons (233.2 liters), however, usable fuel is 57 gallons (216 liters). The helicopter has a maximum range of 273 miles (441 kilometers).
In production from 1946 until 1974, more than 7,000 Model 47 helicopters were built, worldwide. Production of the Model 47G-3B-1 began in March 1962 and a total of 337 of were built. The initial sales price was $46,950 (equivalent to $436,325 in 2022 dollars). NASA bought two -G-3B-1s in 1967. Another 415 were built for military customers, designated TH-13T.
This Bell TH-13T-BF Sioux, 66-4292, was in military service from 1966–1972. It is currently registered as N666SM with the civil designation of Bell 47G-3B-1. (FlugKerl2/Wikipedia)
In 2010, the type certificates for all Bell 47 models were transferred to Scott’s Helicopter Service, Le Sueur, Minnesota, which continues to manufacture parts and complete helicopters.
