7 February 1964: At 1:20 p.m. EST, The Beatles, John Lennon, Paul McCartney, George Harrison and Ringo Starr, arrived in America at John F. Kennedy International Airport from London aboard Pan American World Airways’ Flight 101, a Boeing 707-331, serial number 17683, N704PA, named Jet Clipper Defiance. They were welcomed by an estimated 4,000 fans and 200 journalists.

This was the performers’ first visit to the United States. During their three week tour, they were twice guests on “The Ed Sullivan Show”, with each live television appearance being watched by more than 70,000,000 persons. They performed concerts at the Washington Coliseum, Washington, D.C., and at Carnegie Hall, New York City. The Beatles returned to the United Kingdom, 22 February 1964.

The Boeing 707 was developed from the earlier Model 367–80 prototype, the “Dash Eighty.” It is a four-engine jet transport with swept wings and tail surfaces. The leading edge of the wings are swept at a 35° angle.

The 707-331 had a flight crew of three: pilot, co-pilot and flight engineer. It could carry a maximum of 189 passengers. It was was 152 feet, 11 inches (46.609 meters) long, with a wingspan of 145 feet, 9 inches (44.425 meters) and overall height 42 feet, 1 inches (12.827 meters) at its operating empty weight. The leading edges of the wings and tail surfaces are swept 35°. The fuselage has a maximum diameter of 12 feet, 8.0 inches (3.759 meters). The -321B has a typical empty weight of 142,780 pounds (64,764 kilograms), and a maximum takeoff weight (MTOW) of 327,000 pounds (148,325 kilograms). The usable fuel capacity is 23,855 gallons (90,301 liters).

All 707-series aircraft are powered by four jet engines installed in nacelles below and forward of the wings on pylons. N704PA was powered by four Pratt & Whitney Turbo Wasp JT4A-12 two-spool, axial-flow turbofan engine with a 2-stage fan, 15-stage compressor (8 low-, 7 high-pressure stages) and 3-stage turbine (1 high- and 2 low-pressure stages). It was rated at 14,900 pounds of thrust ( kilonewtons), maximum continuous power, and 17,500 pounds of thrust (77.844 kilonewtons) at 9,355 r.p.m. (N₂) for takeoff. The engine was 12 feet, 0.1 inches (3.660 meters) long, 3 feet, 6.5 inches (1.080 meters) in diameter, and weighed 5,100 pounds (2,313 kilograms).

The 707-331 had a maximum operating speed (MMO) of 0.887 Mach, above 25,000 feet (7,620 meters). At 24,900 feet (7,590 meters), its maximum indicated airspeed (VMO) was 378 knots (435 miles per hour/700 kilometers per hour).

At MTOW, the 707-331 required 10,840 feet (3,304 meters) of runway for takeoff.

The Boeing 707 was in production from 1958 to 1979. 1,010 were built. As of 2013, just ten 707s were still in service.

Jet Clipper Defiance was originally registered to Trans World Airways as N771TW, but never delivered. (It carried a Trans World Airlines model number, 707-331, rather than a Pan American code, 707-321.) It was then sold to Pan Am, delivered 23 March 1960 and registered N704PA. Late in its career, it was leased to several smaller airlines.

Pan Am sold N704PA to Air Vietnam (Hàng không Việt Nam) 21 December 1973. It was registered XV-NJD. After the Fall of Sài Gòn, 30 April 1975, Pan American reacquired the airliner, and then resold it to Aerotron Aircraft Radio, Inc., Long Beach, California. It was re-registered N9230Z. This registration was cancelled 8 January 1976. Jet Clipper Defiance was scrapped at Long Beach inJune 1977.

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 turbofan engines which can produce 47,670 pounds of thrust, each, with water injection (2½ minutes). Its cruise speed is 0.84 Mach (555 miles per hour, 893 kilometers per hour) at 35,000 feet (10,668 meters) and it’s maximum speed is 0.89 Mach (588 miles per hour/946 kilometers per hour). The maximum range at MTOW is 6,100 miles (9,817 kilometers).

The 747 has been in production for 49 years. As of December 2018, 1,548 747s of all models had been built. 205 of these were 747-100 series aircraft.

N736PA had initially been named Clipper Victor, but the name was changed to Clipper Young America for the inaugural New York to London flight when the 747 scheduled to make that flight—Clipper Young America—suffered mechanical problems. The 747 was hijacked on 2 August 1970 and flown to Cuba. After that incident, N736PA was renamed Clipper Victor — its original name. It was destroyed in a collision with another Boeing 747 at Tenerife, Canary Islands, 27 March, 1977.

3 January 1981: Pan American World Airways retired its last Boeing 707 airliner. Pan Am had been the launch customer for the 707. On 20 October 1955 the airline ordered twenty 707s, and later ordered 130 more. The first one, Clipper America, a 707-121, N707PA, was delivered 15 August 1958. On 26 October 1958, N711PA, also named Clipper America,¹ made the first regularly scheduled transatlantic flight by a jet airliner.

The Boeing Model 707-121 was a four-engine jet transport with swept wings and tail surfaces. The leading edge of the wings were swept at a 35° angle. The airliner had a flight crew of four: pilot, co-pilot, navigator and flight engineer.

The 707-121 was 145 feet, 1 inch (44.221 meters) long with a wing span of 130 feet, 10 inches (39.878 meters). The top of the vertical fin stood 41 feet, 8 inches (12.700 meters) high. The 707 pre-dated the ”wide-body” airliners, having a maximum fuselage width of 12 feet, 4.0 inches (3.759 meters). The airliner’s typical operating empty weight is 122,500 pounds (55,565 kilograms). Maximum take off weight is 257,340 pounds (116,727 kilograms).

The first versions were powered by four Pratt & Whitney Turbo Wasp JT3C-6 turbojet engines, producing 11,200 pounds of thrust (49,820 kilonewtons), and 13,500 pounds (60.051 kilonewtons) with water injection. This engine was a civil variant of the military J57 series. It was a two-spool axial-flow turbojet engine with a 16-stage compressor and 2 stage turbine. The JT3C-6 was 11 feet, 6.6 inches (3.520 meters) long, 3 feet, 2.9 inches (0.988 meters) in diameter, and weighed 4,235 pounds (1,921 kilograms).

At MTOW, the 707 required 11,000 feet (3,353 meters) of runway to take off.

The 707-121 had an economical cruise speed of 550 miles per hour (885 kilometers per hour) at 35,000 feet (10,668 meters), and a maximum cruise speed of 593 miles per hour (954 kilometers per hour) at 30,000 feet (9,144 meters)—0.87 Mach. It’s range was 2,800 nautical miles (5,186 kilometers).

The Boeing 707 was in production from 1958 to 1979. 1,010 were built. Production of 707 airframes continued at Renton until the final one was completed in April 1991. As of 2011, 43 707s were still in service.

21 December 1988: Pan American World Airways’ Flight 103 was a scheduled transatlantic passenger flight, originating at Flughafen Frankfurt am Main (FRA) with stopovers at London Heathrow Airport (LHR) and John F. Kennedy International Airport (JFK), with a final destination of Detroit Metropolitan Wayne County Airport (DTW).

The first leg from Frankfurt to London was flown with a Boeing 727. The transatlantic segment of Flight 103 was flown by a Boeing 747-121, N739PA, named Clipper Maid of the Seas. It departed Heathrow at 1825 hours UTC, with 16 crewmembers and 243 passengers. The 747 climbed to the north and leveled off at at 31,000 feet (9,449 meters) at 1856 hours.

At approximately 1903, a time bomb which had been placed inside luggage carried in the airliner’s cargo hold detonated. Explosive decompression magnified the effects of the bomb. The airliner broke into five large sections and fell to the ground at the town of Lockerbie, Scotland.

All 259 persons on board the 747 were killed, as were another 11 persons on the ground.

The time bomb is believed to have been placed aboard the airliner by agents of the Great Socialist People’s Libyan Arab Jamahiriya, acting on orders of the Brotherly Leader and Guide to the Revolution of Libya, Muammar al-Gaddafi. One of these, Abdelbaset Ali Mohmed al-Megrahi, was convicted of 270 counts of murder in a Scottish criminal court seated in The Netherlands. The defense twice appealed the case, but prior to a decision in the second appeal, al-Megrahi dropped his appeal and asked to be released from jail because it was believed that he would very soon die of cancer. The Scottish court did release him and he returned to Libya on 14 August 2009, on board Colonel Gadaffi’s personal aircraft. He reportedly died 20 May 2012.

Boeing delivered N739PA to Pan American 15 February 1970. The airliner was originally named Clipper Morning Light. At the time of the bombing, it had accumulated 72,464 total flight hours.

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 1,536 have been delivered as of September 2017. 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.

3–4 November 1945

3–4 November 1945: On the evening of Saturday, 3 November 1945, the Boeing 314 Honolulu Clipper, NC18601, departed Honolulu, Oahu, Territory of Hawaii, enroute to San Francisco, California. The flying boat was under the command of Captain Sanis E. (“Robby”) Robbins, Pan American Airways, with First Officer Wally Reed, Second Officer Dunbar Carpenter, Radio Officer Jack B. Crawford, First Engineer Dan W. Broadwater, Second Engineer Robert J. Dernberger. There were 13 passengers and 10 crew members on board. The flight to San Francisco was expected to take 11 hours.

Approximately 5 hours into the flight, the number 3 engine (starboard wing, inboard) began to backfire. It was shut down and the propeller feathered. Captain Robbins decided to return to Hawaii. A short while later, the number 4 engine (starboard wing, outboard) also started to malfunction. It continued to run but eventually it was also shut down.

With two engines inoperative, the airplane was unable to maintain altitude. At 11:07 p.m. local, Captain Robbins, in total darkness, brought the flying boat to a “masterful”  landing on the relatively calm surface of the Pacific Ocean. There were no injuries. The airplane suffered minor damage to the port sea wing, and started taking on water.

California Clipper, NC18602, another Boeing 314, also enroute to San Francisco, orbited Honolulu Clipper‘s position to guide rescue ships to scene. The following message was broadcast from Pearl Harbor:

PAN AMERICAN CLIPPER DOWN AT SEA AT 040935Z POSITION 2749N 14802W. PLANE IN GOOD CONDITION. IS ABLE TO COMMUNICATE ON [frequency deleted] KCS VOICECALL C18601 ON [frequency deleted] KCS. INVESTIGATE SIGHTINGS REPORT PERTINENT INFO TO ORIGINATOR.

Freighter S.S. John Henry Payne sighted flares fired from the flying boat and quickly arrived on scene. The ship took all of the passengers on board. Ten crew stayed aboard flying boat.

USS Manila Bay (CVE 61), a Casablanca-class escort aircraft carrier under the command of Captain Leon Johnson, was approximately 60 miles (97 kilometers) away, and had been ordered to take charge of efforts to salvage the airplane.

On arrival, a whale boat was sent to remove the remaining crew members from the flying boat. Wind and waves had increased and it was feared that the boat might damage the hull of the flying boat, so a rubber life raft was used to transfer the Clipper‘s crew to the whale boat. Aircraft mechanics were sent from Manila Bay to attempt to repair the airplane, but were not successful.

Plans were made to rig the airplane for towing. 200 fathoms (1,200 feet/366 meters) of 6-inch (15.2 centimeter) diameter hawser was rigged from the aircraft carrier to the nose of the flying boat. Stabilizing lines were tied to the propeller hubs of the outboard engines. Manila Bay began towing the Honolulu Clipper and was gradually able to increase speed to 6 knots (7 miles per hour/11 kilometers per hour). About an hour after sunset, at about 7:30 p.m., the tow line parted.

Darkness and rising seas made it impossible to rig a new tow. Manila Bay stood by awaiting arrival of USS San Pablo (AVP-30) (Commander Charles Robert Eisenbach), a Barnegat-class seaplane tender, on Tuesday, 6 January, then departed for Pearl Harbor.

During the several days that Honolulu Clipper was afloat in the open ocean, weather increased to the point that it was considered too hazardous to approach it in a small boat, so the aviation tender closed on the airplane directly to try to take it on tow. Unfortunately, San Pablo hit the clipper and caused significant damage.

With salvage impossible, the derelict Honolulu Clipper was now considered a hazard to navigation. It was sunk by 20 mm gun fire from San Pablo.

Honolulu Clipper was the prototype for the Boeing Model 314 series flyjng boat. It had been designed to carry a maximum of 76 passengers and a crew of 10 a distance of 5,200 miles at 184 miles per hour. The design used the wings and engine nacelles of Boeing’s experimental Model 294 (XB-15) very long-range heavy bomber.

The Boeing Model 314 was a large four-engine, high-wing monoplane flying boat designed and built by the Boeing Airplane Company to take off and land on water. It was 106 feet (32.309 meters) long with a wingspan of 152 feet (46.330 meters). It had a maximum take off weight of 82,500 pounds (37,421 kilograms).

The airplane was built at Boeing’s Plant 1, then transported by Barge to Elliot Bay. It carried experimental registration NX18601. Test pilot Edmund Turney (“Eddie”) Allen made the first flight of the prototype on 7 June 1938. He reported that the flying boat had insufficient rudder control and that he had to vary engine power to turn it. The prototype was modified to a twin-tail configuration.

With two vertical fins and rudders, control was improved, but was still insufficient. A third, center, fin was added and this became the production configuration.

The Boeing 314 was powered by four air-cooled, supercharged, 2,603.737-cubic-inch-displacement (42.668 liter) Wright Aeronautical Division Cyclone 14 GR2600A2, two-row, 14-cylinder radial engines with a compression ratio of 7.1:1. They were rated at 1,200 horsepower at 2,100 r.p.m., and 1,550 horsepower at 2,400 r.p.m. for takeoff, burning 91/96 octane gasoline. These engines (also commonly called “Twin Cyclone”) drove three-bladed Hamilton Standard Hydromatic full-feathering constant-speed propellers with a diameter of 14 feet (4.267 meters) through a 16:9 gear reduction. The GR2600A2 was 5 feet, 2.06 inches (1.576 meters) long and 4 feet, 7 inches (1.387 meters) in diameter. It weighed 1,935 pounds (878 kilograms). The engines could be serviced in flight, with access through the wings.

The Boeing 314 had a maximum speed of 199 miles per hour (320 kilometers per hour), with a range of 3,685 miles (5,930 kilometers) at its normal cruising speed of 183 miles per hour (295 kilometers per hour). Its service ceiling was 13,400 feet (4,084 meters). The fuel capacity was 4,246 gallons (16,073 liters).

Boeing built six Model 314 and another six 314A flying boats for Pan American Airways and British Overseas Airways Corporation. Pan Am paid $549,846.55 for each 314, about $9,545,726.07 in 2017 dollars, and Boeing lost money on every one sold.

Honolulu Clipper was leased to the United States Navy by Pan American Airways, 17 December 1942, and assigned Bureau of Aeronautics serial number (“Bu. No.”) 48227. The airplane continued to be operated by Pan Am crews.

Sanis E. (“Robby”) Robbins was born at Matthews, Indiana, 17 September 1898. He was the sixth of seven children of William S. Robbins, a real estate agent, and Sarah Ellen Brokaw Robbins.

Robbins enlisted as a Private, United States Army, at Camp Dodge, Iowa, 26 June 1916. He was promoted to Private First Class on 1 August 1916, and to Corporal, 18 December 1916. Corporal Robbins was hospitalized at Brownsville, Texas, 4–23 January 1917. He was released from military service at Fort Des Moines, Iowa, 20 February 1917, shortly before the United States entered World War I. A 1920 Air Service Information Circular listed Second Lieutenant Sanis E. Robbins as a pursuit pilot, residing at Cassia, Florida.

Robby Robbins married Miss Virginia J. Bing. They would have three children.

Robbins was commissioned as a Lieutenant Commander, United States Naval Reserve, 15 September 1940. He held this rank until at least 1955.

Captain Sanis E. Robbins died at Palo Alto, California, 8 August 1961, at the age of 62 years. He was buried at the Golden Gate National Cemetery, San Bruno, California.
