12 June 1994: At 11:45 a.m., Boeing test pilots John E. Cashman and Kenny Higgins took the first Boeing 777-200 airliner, line number WA001, FAA registration N7771, on its first flight. Before taking off from Paine Field, Boeing’s president, Phil Condit, told Cashman, “Good luck, John. And no rolls!”, referring to the famous incident when Alvin M. “Tex” Johnston rolled the Model 367–80 prototype of the 707 airliner over Lake Washington, 6 August 1955.

The 777’s first test flight lasted 3 hours, 48 minutes. This was the longest first flight of any of Boeing’s airliners. It reached a maximum altitude of 19,000 feet (5,791 meters) and accomplished all tests on the flight plan, including shutting down and restarting an engine in flight.

The Boeing 777-200 is operated by two pilots and, depending on its configuration can carry 314 to 440 passengers. It is 209 feet, 1 inch (63.729 meters) long with a wingspan of 199 feet, 11 inches (60.935 meters) and overall height of 60 feet, 9 inches (18.517 meters). The fuselage has a diameter of 20 feet, 4 inches (6.198 meters). The airliner has an empty weight of 297,300 pounds (134,853 kilograms) and maximum takeoff weight of 545,000 pounds (247,208 kilograms).

WA001 was originally powered by two Pratt & Whitney PW4074 two-spool high-bypass-ratio turbofan engines which produce 77,000 pounds of thrust, each. Production airliners were equipped with PW4077 engines with the same thrust. General Electric and Rolls-Royce turbofans could also be ordered.

Boeing 777s have a cruise speed of 0.84 Mach (560 miles per hour, 901 kilometers per hour) and maximum speed of 0.89 Mach (590 miles per hour, 950 kilometers per hour). The service ceiling is 43,100 feet (13,137 meters). The 777-200 has a maximum range of 6,027 miles (9,700 kilometers) with maximum payload aboard.

The 777 series was the most comprehensively tested airplane in history. Nine aircraft were used in the test program. WA001 was in testing until April 1997, by which time it had accumulated 1,729 flight hours and another 1,033 hours of ground testing.

Purchased by Cathay Pacific, the first “Triple Seven” was completely refurbished and equipped for passenger service, configured as a 777-267. The engines were replaced by two Rolls-Royce RB211 Trent 884B-17 high-bypass turbofan engines. These engines are rated at 85,430 pounds of thrust for takeoff (5 minutes limit). Because of their lighter weight, the empty weight of the airliner was reduced approximately 7,500 pounds (3,400 kilograms). The airliner was rolled out of the factory for the second time 31 October 2000, and was delivered to the Cathay Pacific on 6 December, registered B-HNL. WA001 was retired 1 June 2018 and placed in storage at Xiamen Gaoqi International Airport (XMN), Xiamen, Fujian Province, People’s Republic of China. Reportedly, the first Triple-Seven will become part of the collection of the Museum of Flight at Boeing Field, Seattle, Washington.

The 777 was produced in the 777-200 configuration, followed the 777-200ER (“extended range”) and 777-200LR (“longer range”) variants, a longer 777-300ER and a 777F freighter. A tanker version has been proposed. Eighty-eight 777-200 airliners were built before production halted in favor of the -200ER and -200LR models.

As of April 2018, 1,547 Boeing 777s of all models have been delivered. At that time, there were 60 777-300ER, 42 777F freighters, and 326 777Xs on order.

1 May 1943

Secretary of War Henry L. Stimson presents the Medal of Honor to Staff Sergeant Maynard Harrison Smith, United States Army Air Corps. (U.S. Air Force)

MEDAL OF HONOR

SMITH, MAYNARD H. (Air Mission)

Rank and organization: Sergeant, U.S. Army Air Corps, 423d Bombardment Squadron, 306th Bomber Group.

Place and date: Over Europe, 1 May 1943.

Entered service at: Caro, Michigan.

Born: 1911, Caro Michigan.

G.O. No.: 38, 12 July 1943.

Medal of Honor
Medal of Honor

Citation: “For conspicuous gallantry and intrepidity in action above and beyond the call of duty. The aircraft of which Sgt. Smith was a gunner was subjected to intense enemy antiaircraft fire and determined fighter airplane attacks while returning from a mission over enemy-occupied continental Europe on 1 May 1943. The airplane was hit several times by antiaircraft fire and cannon shells of the fighter airplanes, 2 of the crew were seriously wounded, the aircraft’s oxygen system shot out, and several vital control cables severed when intense fires were ignited simultaneously in the radio compartment and waist sections. The situation became so acute that 3 of the crew bailed out into the comparative safety of the sea. Sgt. Smith, then on his first combat mission, elected to fight the fire by himself, administered first aid to the wounded tail gunner, manned the waist guns, and fought the intense flames alternately. The escaping oxygen fanned the fire to such intense heat that the ammunition in the radio compartment began to explode, the radio, gun mount, and camera were melted, and the compartment completely gutted. Sgt. Smith threw the exploding ammunition overboard, fought the fire until all the firefighting aids were exhausted, manned the workable guns until the enemy fighters were driven away, further administered first aid to his wounded comrade, and then by wrapping himself in protecting cloth, completely extinguished the fire by hand. This soldier’s gallantry in action, undaunted bravery, and loyalty to his aircraft and fellow crewmembers, without regard for his own personal safety, is an inspiration to the U.S. Armed Forces.”

Sergeant Smith was a ball turret gunner on a B-17 Flying Fortress on his first combat mission. The bomber was so badly damaged that, on landing, the airplane’s structure failed from battle damage and it broke in half. There were over 3,500 bullet and shrapnel holes.

Maynard Harrison Smith was born at Caro, Michigan, 19 May 1911. He was the second child of Henry Harrison Smith, a lawyer, and Mary Christine Gohs Smith, a school teacher.

Smith worked as a clerk in a government insurance office. He married Miss Arlene E. McCreedy at Ferndale, Michigan, 31 July 1929. They had a daughter, Barbara Lou Smith. They divorced 22 October 1932. He later married his second wife, Helene Gene Gunsell, at Caro, Michigan, 30 March 1941.

Maynard Smith enlisted in the U.S. Army Air Corps, 31 August 1941. He was trained as an aerial gunner, and on completion, was promoted to the rank of staff sergeant. He was assigned as a ball turret gunner in a B-17 combat crew of the 423rd Bombardment Squadron (Heavy), 306th Bombardment Group (Heavy), based at RAF Thurleigh, Bedfordshire, England.

Following the 1 May mission, Staff Sergeant Smith flew only four more combat missions before a medical board diagnosed him with Operational Exhaustion. He was removed from flight status and reverted to his initial rank of private.

While stationed in England, Sergeant Smith met Miss Mary Rayner, a British subject and USO volunteer. They were married in 1944. They would have four children.

Sergeant Smith was released from active duty, 26 May 1945.

Following World War II, Smith worked for the Department of the Treasury. He later founded Police Officers Journal, a magazine oriented toward law enforcement officers.

Based on an examination of certain facts in his life, as well as anecdotes by persons who knew him, it is fair to say the Maynard Smith was a troubled individual. But the extreme courage he displayed on 1 May 1943 cannot be denied.

Maynard Smith died at St. Petersburg, Florida, 11 May 1984 at the age of 72 years. He was buried at Arlington National Cemetery.

Staff Sergeant Maynard Harrison Smith, United States Army Air Forces, was the first of only five Air Force enlisted airmen to be awarded the Medal of Honor during World War II. He was also awarded the Air Medal, with one oak leaf cluster (two awards).

Boeing B-17F-65-BO Flying Fortress 42-29649 was delivered to Denver, Colorado, 29 January, 1943. After crossing the North Atlantic Ocean, the new bomber was assigned to the 423rd Bombardment Squadron (Heavy), 306th Bombardment Group (Heavy) at RAF Thurleigh, near Bedford, Bedfordshire, England, 24 March 1943. It was identified by the letters RD-V painted on its fuselage.

On 1 May 1943, 42-29649 was one of 18 B-17s of the 306th Bombardment Group assigned to attack German Kriegsmarine submarine pens at Saint-Nazaire, on the Atlantic coast of France. Another 60 B-17s from three other groups were also part of the mission. Only 12 bombers from the 306th arrived over the target, which was heavily obscured by clouds. Each bomber carried two 2,000-pound (907 kilogram) General Purpose bombs, which were dropped from 25,200 feet (7,681 meters) on a heading of 270°. After a 20-second bomb run, the group released its bombs at 11:26 a.m.

Flying away from the target area, the 306th flew over the city of Brest at low altitude. 42-29649 was hit by anti-aircraft fire. The group was then attacked by 15–20 Luftwaffe Focke-Wulf Fw 190 fighters. Two bombers were shot down over the city and a third ditched near the coast. -649 caught fire and three crewmen bailed out over the water and were lost.

Of the 78 B-17s dispatched, 7 were lost. 73 crewmembers were listed as Missing in Action, 18 Wounded in Action and 2 Killed in Action.

On 1 May 1943, 42-29649 was flown by Captain Lewis P. Johnson, Jr., aircraft commander/pilot; 1st Lieutenant Robert McCallum, co-pilot; 1st Lieutenant Stanley N. Kisseberth, navigator; Staff Sergeant J.C. Melaun, nose gunner and bombardier; Technical Sergeant William W. Fahrenhold, flight engineer/top turret gunner; Staff Sergeant Maynard H. Smith, ball turret gunner; Technical Sergeant Henry R. Bean, radio operator; Staff Sergeant Robert V. Folliard, waist gunner; Staff Sergeant Joseph S. Bukacek, waist gunner; Sergeant Roy H. Gibson, tail gunner. Sergeants Bean, Folliard and Bukacek were killed in action.

27 March 1977

27 March 1977: The deadliest accident in the history of aviation occurred when two Boeing 747 airliners collided on the runway on the island of Tenerife in the Canary Islands. 583 people died.

A terrorist incident at Gran Canaria International Airport (LPA) on the island of Gran Canaria resulted in the airport being closed for flight operations. This forced many trans-Atlantic airliners to divert to the smaller Los Rodeos Airport (TFN) on Tenerife. The ramp and taxiways at Los Rodeos were congested and refuelers were overwhelmed by the increased traffic, which led to many delays.

Los Rodeos Airport has only one runway, Runway 12/30, with a parallel taxiway and four short taxiways joining the two.

Pan American World Airways’ Flight 1736, a Boeing 747-121, FAA registration number N736PA, named Clipper Victor ¹ was ready for takeoff with 380 passengers and crew, but had to “back taxi” on Runway 12 (“One-Two”) because the parallel taxiway was jammed with airplanes. The airliner proceeded east-southeast, intending to exit the runway to the parallel taxiway after passing by the congestion around the terminal.

Also on the runway was Koninklijke Luchtvaart Maatschappij (KLM) Flight 4805, a Boeing 747-206B, PH-BUF, named Rijn (“Rhine”). The KLM jumbo jet had 248 passengers and crew members on board. Flight 4805 had back-taxied for the entire length of Runway 12, then made a 180° turn to align itself with Runway 30, the “active” runway.

Weather at the time of the accident was IFR, with low clouds and fog. Visibility on the runway was restricted to about 1,000 feet (305 meters). Takeoff rules required a minimum of 2,300 feet (701 meters). What happened next was a misunderstanding between the air traffic controllers and the crew of both airliners.

The control tower instructed KLM 4805 to taxi into position on Runway 30 (“Three-Zero”) for takeoff, and to hold there for release. The Pan Am airliner was told to taxi off the runway and to report when clear. The tower controllers could not see either airliner because of the fog, and their flight crews could not see each other.

The aircraft commander of the Dutch airliner, that company’s Chief Pilot and Chief Flight Instructor, Captain Jacob Veldhuyzen Van Zanten, apparently misunderstood what was occurring and radioed to the tower that he was taking off. He then accelerated.

The crew in the Pan Am airliner heard the KLM pilot report that he was taking off, immediately turned left and ran the engines up to full throttle in order to try to get off the runway. With the KLM 747 accelerating through the fog, its flight crew belatedly realized that the other airliner was still ahead of them. Too late to stop, they applied full power and pulled the nose up trying to takeoff. The tail of their airplane actually dragged over sixty feet (18 meters) on the runway because its extreme nose up angle.

KLM 4805 lifted off about 300 feet (91 meters) from Pan Am 1736, and because of the high angle of attack, its nose wheel actually passed over American airliner’s fuselage, but the rest of the Dutch airplane hit at 140 knots (259 kilometers per hour). Clipper Victor was ripped in half, caught fire and exploded. Rijn crashed about 250 yards (229 meters) down the runway, and it also caught fire and exploded.

All 248 people aboard the Royal Dutch Airlines airplane were killed. Miraculously, there were 61 survivors from the Pan Am Clipper, including the co-pilot, but the remaining 335 died.

The 747-100 series was the first version of the Boeing 747 to be built. It was operated by a flight crew of three and was designed to carry 366 to 452 passengers. It is 231 feet, 10.2 inches (70.668 meters) long with a wingspan of 195 feet, 8 inches (59.639 meters) and overall height of 63 feet, 5 inches (19.329 meters). The interior cabin width is 20 feet (6.096 meters), giving it the name “wide body.” Its empty weight is 370,816 pounds (168,199 kilograms) and the Maximum Takeoff Weight (MTOW) is 735,000 pounds (333,390 kilograms).

The 747-100 is powered by four Pratt & Whitney JT9D-7A high-bypass ratio turbofan engines. The JT9D is a two-spool, axial-flow turbofan engine with a single-stage fan section, 14-stage compressor (11 high- and 3 low-pressure stages) and 6-stage turbine (2 high- and 4 low-pressure stages). The engine is rated at 46,950 pounds of thrust (208.844 kilonewtons), or 48,570 pounds (216.050 kilonewtons) with water injection (2½-minute limit). This engine has a maximum diameter of 7 feet, 11.6 inches (2.428 meters), is 12 feet, 10.2 inches (3.917 meters) long and weighs 8,850 pounds (4,014 kilograms).

The 747-100 has a cruise speed of 0.84 Mach (555 miles per hour, 893 kilometers per hour) at 35,000 feet (10,668 meters). The maximum certificated operating speed is 0.92 Mach. The airliner’s maximum range is 6,100 miles (9,817 kilometers).

The Boeing 747 has been in production for 48 years. More than 1,520 have been delivered to date. 205 of these were the 747-100 series. The U.S. Air Force has selected the Boeing 747-8 as the next presidential transport aircraft.

¹ Pan American World Airways’ Boeing 747 Clipper Victor was the very first Boeing 747 in service. It made its first commercial passenger flight, New York to London, 22 January 1970. Another airliner, Clipper Young America, was scheduled to  make that flight but suffered mechanical problems shortly before departure. Clipper Victor was substituted, but Pan Am changed the airliner’s name to Clipper Young America. On 2 August 1970, N736PA was hijacked to Cuba, and afterwards, to avoid the negative publicity, the name of the 747 was changed back to Clipper Victor.

10 January 1964

Boeing B-52H-170-BW 61-023
Boeing B-52H-170-BW Stratofortress 61-023. (U.S. Air Force)

10 January 1964: This Boeing B-52H Stratofortress, serial number 61-023, flown by Boeing test pilot Charles F. (“Chuck”) Fisher, was conducting structural testing in turbulence near East Spanish Peak, Colorado. The other crew members were pilots Richard V. Curry and Leo Coer, and navigator James Pittman. Dick Curry was flying the airplane and Chuck Fisher, the aircraft commander, was in the co-pilot’s position. Pittman was on the lower deck.

The bomber was carrying two North American Aviation GAM-77 Hound Dog cruise missiles on pylons under its wings.

The Boeing B-52 Stratofortress had been designed as a very high altitude penetration bomber, but changes in Soviet defensive systems led the Strategic Air Command to change to very low altitude flight as a means of evading radar. This was subjecting the airframes to unexpected stresses. “Ten-Twenty-Three” (its serial number was 61-023, shortened on the vertical fin to “1023”) had been returned to Boeing Wichita by the Air Force to be instrumented to investigate the effects of high-speed, low-altitude flight on the 245-ton bomber.

Flying at 14,300 feet (4,359 meters) and 345 knots (397 miles per hour, 639 kilometers per hour), indicated air speed, the airplane encountered severe clear air turbulence and lost the vertical stabilizer. Several B-52s had been lost under similar circumstances. (Another, a B-52D, was lost just three days later at Savage Mountain, Maryland.)

Chuck Fisher immediately took control of the B-52. He later reported,

“As the encounter progressed, a very sharp-edged blow which was followed by many more. We developed an almost instantaneous rate of roll at fairly high rate. The roll was to the far left and the nose was swinging up and to the right at a rapid rate. During the second portion of the encounter, the airplane motions actually seemed to be negating my control inputs. I had the rudder to the firewall, the column in my lap, and full wheel, and I wasn’t having any luck righting the airplane. In the short period after the turbulence I gave the order to prepare to abandon the airplane because I didn’t think we were going to keep it together.”

A Boeing report on the incident, based on installed sensors and instrumentation aboard -023, said that the bomber had

“. . . flown through an area containing the combined effects of a (wind) rotor associated with a mountain wave and lateral shear due to airflow around a mountain peak. . . Gust initially built up from the right to a maximum of about 45 feet per second [13.7 meters per second] (TAS), then reversed to a maximum of 36 feet per second [11 meters per second] from the left, before swinging to a maximum of about 147 feet per second [44.8 meters per second] from the left followed by a return to 31 feet per second [9.5 meters per second].”

Fisher flew the bomber back to Wichita and was met by a F-100 Super Sabre chase plane. When the extent of the damage was seen, the B-52 was diverted due to the gusty winds in Kansas. Six hours after the damage occurred, Chuck Fisher safely landed the airplane at Eaker Air Force Base, Blythville, Arkansas. He said it was, “the finest airplane I’ve ever flown.”

The B-52H is a sub-sonic, swept wing, long-range strategic bomber. It has a crew of five. The airplane is 159 feet, 4 inches (48.6 meters) long, with a wing span of 185 feet (56.4 meters). It is 40 feet, 8 inches (12.4 meters) high to the top of the vertical fin. Maximum Takeoff Weight (MTOW) is 488,000 pounds (221,353 kilograms).

There are eight Pratt & Whitney TF33-PW-3 turbofan engines mounted in two-engine pods suspended under the wings on four pylons. Each engine produces a maximum of 17,000 pounds of thrust (75.620 kilonewtons). The TF-33 is a two-spool axial-flow turbofan engine with 2 fan stages, 14-stage compressor stages (7 stage intermediate pressure, 7 stage high-pressure) and and 4-stage turbine (1 stage high-pressure, 3-stage low-pressure). The engine is 11 feet, 10 inches (3.607 meters) long, 4 feet, 5.0 inches (1.346 meters) in diameter and weighs 3,900 pounds (15,377 kilograms).

The B-52H can carry approximately 70,000 pounds (31,750 kilograms) of ordnance, including free-fall bombs, precision-guided bombs, thermonuclear bombs and cruise missiles, naval mines and anti-ship missiles.

The bomber’s cruise speed is 520 miles per hour (837 kilometers per hour) and its maximum speed is 650 miles per hour (1,046 kilometers per hour) at 23,800 feet (7,254 meters) at a combat weight of 306,350 pounds. Its service ceiling is 47,700 feet (14,539 meters) at the same combat weight. The unrefueled range is 8,000 miles (12,875 kilometers).

With inflight refueling, the Stratofortress’s range is limited only by the endurance of its five-man crew.

The B-52H is the only version still in service. 102 were built and as of 27 September 2016, 76 are still in service. Beginning in 2013, the Air Force began a fleet-wide technological upgrade for the B-52H, including a digital avionics and communications system, as well as an internal weapons bay upgrade. The bomber is expected to remain in service until 2040.

7 December 1972: At 05:33:00.63 UTC (12:33 a.m., Eastern Standard Time), Apollo 17, the last manned mission to The Moon in the 20th century, lifted off from Launch Complex 39A at the Kennedy Space Center, Cape Canaveral, Florida. The destination was the Taurus-Littrow Valley.

The Mission Commander, on his third space flight, was Eugene A. Cernan. The Command Module Pilot was Ronald A. Evans, on his first space flight, and the Lunar Module Pilot was Harrison H. Schmitt, also on his first space flight.

Schmitt was placed in the crew because he was a professional geologist. He replaced Joe Engle, an experienced test pilot who had made sixteen flights in the X-15 hypersonic research rocketplane. Three of those flights were higher than the 50-mile altitude, qualifying Engle for U.S. Air Force astronaut wings.

The launch of Apollo 17 was delayed for 2 hours, 40 minutes, due to a minor mechanical malfunction. When it did liftoff, the launch was witnessed by more than 500,000 people.

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.

Apollo 17 launched 3 years, 4 months, 20 days, 16 hours, 1 minute, 0 seconds after Apollo 11, the first manned flight to The Moon.
