The Associated Press wire service reported the story:

NAVY’S BIG FLYING BOAT MARSHALL MARS CARRIES 301 PERSONS

SAN FRANCISCO, May 19—(AP)—The Navy’s big flying boat Marshall Mars carried a record load of 301 passengers—plus seven crewmen—on a flight to San Diego today.

It had never carried more than 269 passengers before.

The 1:52 p.m. takeoff, from the naval air station at Alameda, across the bay, was uneventful.

Today’s passengers are personnel of Air Group 5, Alameda Naval Air Station, who are being transferred to San Diego. Mattresses on the floor were provided for men unable to find seats.

The Martin JRM Mars was a large four-engine flying boat transport built by the Glenn L. Martin Company for the U. S. Navy. Only five were built, four designated JRM-1, with the last one being a JRM-2. Each airplane was given an individual name derived from the names of island chains in the Pacific Ocean: Marianas MarsHawaii MarsPhilippine MarsMarshall Mars and Caroline Mars. These airplanes were used to transport personnel and cargo between the West Coast of the United States and the Hawaiian Islands. All were upgraded to JRM-3.

The Martin JRM-3 Mars had a normal crew of 4, with accommodations for a relief crew. It was designed to carry 133 combat troops or 32,000 pounds (14,515 kilograms) of cargo. It was 117 feet, 3 inches (35.738 meters) long with a wingspan of 200 feet (60.960 meters) and height of 38 feet, 5 inches (11.709 meters). The flying boat had an empty weight of 75,573 pounds (34,279.3 kilograms) and a loaded weight of 90,000 pounds (40,823.3 kilograms). The maximum takeoff weight (MTOW) was 165,000 pounds (74,842.7 kilograms).

A NASA publication states, “A zero-lift drag coefficient of 0.0233 and a maximum lift-drag ratio of 16.4 made the JRM the most aerodynamically efficient of any of of the flying boats. . . .”

The Martin Mars was powered by four air-cooled, supercharged, direct-fuel-injected, 3,347.662-cubic-inch-displacement (54.858 liter) Wright Aeronautical Division R-3350-24WA (Cyclone 18 825C18BD1) (also known as the Duplex-Cyclone), a two-row 18-cylinder radial engines with a compression ratio of 6.70:1 and water/alcohol injection. This engine has a normal power rating of 2,000 horsepower at 2,400 r.p.m at 5,500 feet (1,676 meters) and 1,800 horsepower at 2,400 r.p.m. at 15,000 feet (4,572 meters). The engine’s takeoff power rating is 2,500 horsepower at 2,900 r.p.m. 100/130 octane aviation gasoline was required. The engines drove four-bladed 16 foot, 8 inch (5.080 meter) Curtiss Electric variable-pitch propellers through a 0.4375:1 gear reduction. (After modification to the JRM-3, the propellers on the inboard engines were reversible.) The R-3350-24WA is 6 feet, 8.58 inches (2.047 meters) long, and 4 feet, 6.13 inches (1.375 meters) in diameter. Its dry weight is 2,822 pounds (1,280 kilograms).

The JRM-3 had a cruise speed of 190 miles per hour (305.8 kilometers per hour) and a maximum speed of 221 miles per hour (355.7 kilometers per hour). The service ceiling was 14,600 feet (4,450 meters) and its range was 5,000 miles (8,046.7 kilometers).

On 5 April 1950, Marshall Mars had an engine fire and made an emergency landing off Diamond Head, Hawaii. The crew was rescued but the airplane exploded and sank. The wreck was discovered on the sea floor in August 2004.

The remaining airplanes were later converted to fire fighting airplanes in Canada. Only two remain.

25 March 1956: At approximately 10:50 a.m., the first of two prototype Martin XB-51 three-engine attack bombers, serial number 46-685, crashed on takeoff from Runway 22 at El Paso International Airport (ELP). The pilot, Major James O. Rudolph, United States Air Force, survived the crash although he was  seriously burned. Staff Sergeant Wilbur R. Savage, 28, engineer, was killed. Major Rudolph died of injuries 16 April 1956.

Pieces of wreckage were marked “Gilbert XF-120” which had been painted on the airplane for the filming of the William Holden, Lloyd Nolan movie, “Toward The Unknown.” (Toluca Productions, 1956). The second prototype, 46-686, had previously crashed at Edwards AFB.

A newspaper article from the El Paso Times is quoted below [I have corrected some typographical errors]:

03/26/1956

Bill Feather
El Paso Times

A sleek jet bomber, carrying a full load of fuel, crashed while attempting a take-off at International Airport Sunday morning, killing the flight engineer and seriously injuring the pilot.

The XB-51, the only one of its type in existence, smashed through the fence at the end of the southwest runway and then began to disintegrate, spreading wreckage along a 250-yard trail.

Only the tail section of the three-engine bomber was left intact.

Name of the dead man, a 28-year-old staff sergeant was withheld pending notification of next of kin.

Flying the aircraft was Maj. James O. Rudolph, 36, one of the top test pilots in the Air Force.

He suffered severe burns and was taken Sunday afternoon in an emergency flight to Brooke Army Hospital in San Antonio.

The XB-51, based at Edwards Air Force Base in Muroc, Calif., was being flown to Eglin Air Force Base, Florida, where it was to be used in the filming of a Warner Brothers movie, “Toward the Unknown.”

Identification of the aircraft was confused for a short time after the crash.

A piece of wreckage with the notation “Gilbert XF-120” was found nearby.

HAD REFUELED

Air Force spokesmen explained that the XF designation had been painted on the plane for use in the movie.

The airplane had been refueled at International Airport and started its takeoff at 10:30 a.m.

Witnesses said the plane got about three feet above the ground and suddenly settled. The tail dragged first and then the rest of the airplane settled, running at high speed.

It ripped through a barbed wire fence at the end of the runway, raced across Airport Road and then began to go to pieces.

After crashing, it burned and several explosions threatened firemen, rescuers and spectators who crowded around the flaming aircraft.

First person to the scene of the crash was Eddie C. Wilkerson, 1106 Del Monte Drive, tennis coach at Austin High School.

“I was just turning into the road to the airport when the plane was taking off. I don’t believe it ever got airborne.

“I looked back and saw a big ball of smoke, so I just wheeled my car around.”

Wilkerson said that when he arrived, the major was lying on the ground about 15 feet from the burning wreckage.

“His clothes were burning so I started tearing them off.”

Other witnesses to the crash arrived and helped Wilkerson move the major to a safer place, away from the intense heat of the flaming aircraft.

Capt. John D. Chandler, a doctor at the Biggs Hospital, was at the airport when the crash occurred and he was one of the first persons at the scene. He administered aid to the injured man until an ambulance arrived. Later Capt. Chandler flew to San Antonio with Maj. Rudolph.

A fire truck from International Airport was rushed to the scene almost as soon as the plane stopped its forward motion.

Sunday drivers were attracted to the scene by the tower of smoke and the heavy traffic delayed the arrival of fire trucks from Biggs Air Force Base.

The plane was one of two XB-51s built by Martin Aircraft Co. and was completed in 1953.

The first one crashed at Muroc, Calif., in 1952.

Air Force spokesmen said the aircraft was comparable to the B-47, which was accepted instead of the XB-51 for use in the Air Force.

Its three jet engines one in each wing and on in the fuselage, were capable of driving the craft at tremendous speeds. The aircraft had broken the sound barrier, spokesmen said.

Its sleek lines gave it the appearance of a fighter rather than a medium bomber.

Normally, the airplane carried a crew of three.

Recently it had been used in assisting the Army in missile and anti-aircraft development at Aberdeen Proving Ground, Md.

A board of officers was investigation the crash and two Air Force colonels arrived at Biggs Air Force Base from Muroc Sunday afternoon.

Military police from Ft. Bliss and Air Police patrolled the area about the crash Sunday afternoon, keeping away the curious.

James Otto Rudolph was born at Marion, Ohio, 8 February 1920, the first of two children of of Frank Otto Rudolph, a German immigrant who was employed as a secretary for the YMCA, and Helen Claire Shafer Rudolph.

Following two years of college, Rudolph enlisted as an Aviation Cadet, U.S. Army Air Corps, at Detroit, Michigan, 17 March 1941. He was 6 feet, 1inch (1.854 meters) tall and weighed 175 pounds (79.4 kilograms). He was commissioned as a Second Lieutenant, Air Reserve, 31 October 1941,and was promoted to First Lieutenant, Army of the United States (Air Corps), 5 August 1942. He was again promoted, to Captain, 15 June 1943. Following the end of World War II, Rudolph was promoted to the rank of Major, 19 September 1946. He remained in the Air Force, but with military needs shrinking, he reverted to the rank of First Lieutenant, with date of rank, 7 December 1944.

James Rudolph married Clara D.    in 194–

Major Rudolph graduated from the U.S. Air Force Experimental Flight Test Pilot School, Class 54-A, 2 July 1954. As a test pilot at Edwards Air Force Base, Rudolph was a project pilot in the FICON program in which Republic RF-84K Thunderflash reconnaissance planes were carried by modified Convair RB-36D bombers.

During his military career, Major Rudolph had been awarded the Air Medal with three oak leaf clusters (four awards).

After the crash on 25 March 1956, Major Rudolph was taken to Brooke Army Hospital, Fort Sam Houston, Texas, suffering from 2nd and 3rd degree burns over 38% of his body. He contracted septicemia and died there, 16 April 1956. He is buried at Arlington National Cemetery.

The first Martin XB-51, 46-585, in flight. (U.S. Air Force)

The Glenn L. Martin Co. XB-51 was a prototype jet-powered ground attack bomber. It was an unusual design for its time. The airplane had mid-mounted, variable-incidence swept wing, a T-tail and tandem landing gear with a configuration similar to that used on the Boeing B-47 Stratojet (and which had been tested using a Martin B-26 Marauder medium bomber.)

The XB-51 was operated by a pilot in a single-place cockpit with a bubble canopy, and a navigator station inside the fuselage, below and behind the pilot. The prototype was 85 feet, 1 inch (25.933 meters) long with a wingspan of 53 feet, 1 inch (16.180 meters) and overall height of 17 feet, 4 inches (5.283 meters). The total wing area was 548.0 square feet (50.9 square meters). The airplane had an empty weight of 30,906 pounds (14,019 kilograms) and a maximum overload takeoff weight of 62,452 pounds (28,328 kilograms).

The wings of the XB-51 were swept aft to 35° and had 6° anhedral. The wings’ angle of incidence (the relation of the chord to the fuselage longitudinal axis) could be adjusted to increase lift for takeoff and landing. They had 2° negative twist and were equipped with leading edge slats for improved low speed performance. Instead of ailerons, the XB-51 used spoilers.

Power was supplied by three General Electric J47-GE-13 turbojet engines, with two located in nacelles outboard of the forward fuselage on 45° pylons, and a third installed in the tail with its intake on top of the fuselage. The J47-GE-13 was an axial-flow turbojet with a 12-stage compressor and single stage turbine. It had a normal power rating of 4,320 pounds of thrust (19.216 kilonewtons) at 7,370 r.p.m.; military power, 5,200 pounds (23.131 kilonewtons) at 7,950 r.p.m. (30-minute limit); and maximum power rating of 6,000 pounds(26.689 kilonewtons) at 7,950 r.p.m., with water/alcohol injection (5-minute limit). The engine was 12 feet, 0.0 inches (3.658 meters) long, 3 feet, 3.0 inches (0.991 meters) in diameter and weighed 2,525 pounds (1,145 kilograms). A Rocket Assisted Takeoff (RATO) system was also installed.

The XB-51 had a maximum speed of 560 knots (644 miles per hour/1,037 kilometers per hour) at Sea Level—0.85 Mach. The service ceiling was 39,400 feet (12,009 meters) and the maximum ferry range was 1,255 nautical miles (1,444 statute miles/2,324  kilometers).

Armament was planned for a maximum bomb load of 10,400 pounds (4,717 kilograms) carried internally in a rotary bomb bay, and eight M39 20 mm revolving autocannon mounted in the nose with 160 rounds of ammunition per gun. 5-inch High Velocity Aerial Rockets (HVAR) could be carried under the wings or in the bomb bay.

15 January 1915: At San Diego, California, Lieutenant Byron Quinby Jones, Aviation Section, Signal Corps, United States Army, set a flight endurance record of 8 hours, 53 minutes, flying a Glenn L. Martin Company Martin T Army Tractor. The flight consumed 30 gallons (114 liters) of gasoline. Lieutenant Jones estimated that he had sufficient fuel remaining for another two hours in the air, but approaching darkness forced him to land.

For this and other flights at San Diego, Lieutenant Jones was awarded the Mackay Trophy.

The Mackay Army Aviation Cup was established in 1911 by Clarence Hungerford Mackay, Chairman of the Board of Directors of the Postal Telegraph and Cable Corporation. Now known as the Mackay Trophy, it is awarded yearly for “the most meritorious flight of the year” by U.S. Air Force personnel.

Lieutenant Jones was the sixth aviator to be awarded the trophy. The trophy is kept at the Smithsonian Institution National Air and Space Museum. It was appraised in the 1960s at a value of $65,000, though it was also estimated that it would cost $650,000 to duplicate it.

Lieutenant Byron Quinby Jones, 14th Cavalry Regiment, United States Army

Byron Quinby Jones was born at Henrietta, New York, 9 April 1988. He was one of four children of Samuel Titus Jones and Sarah Minerva Quinby Jones. He attended School 24 and East High School, Rochester, New York.

Jones entered the United States Military Academy, West Point, New York, 15 June 1907, and graduated 12 June 1912 with a bachelor of science degree. He was commissioned as a second lieutenant in the 14th Cavalry Regiment, United States Army.

Lieutenant Jones volunteered for pilot training and was sent to the Signal Corps Aviation School at North Field, San Diego, California. After earning a rating as one of the earliest U.S. military pilots and serving for a year with an active squadron, Jones was promoted to the rank of first lieutenant, Aviation Section, Signal Corps, 23 November 1914. He was then sent to the Massachusetts Institute of Technology (MIT) for the very first post-graduate course in aeronautical engineering.

In addition to he endurance records, “B.Q.” Jones was also the first Army pilot to perform a loop, an intentional stall and recovery, and a “tail spin.”

During World War I, Jones rose to the temporary rank of lieutenant colonel.

Jones married Mrs. Evelyn Clark Chadwick (née Evelyn Kennerly Clark, grand daughter of William Clark, co-leader with Meriwether Lewis of the 1804–1806 Lewis and Clark Expedition), 4 June 1917.

For the next twenty-four years, Jones steadily rose in rank and was an important figure in Army aviation. Assigned to the newly established Air Service, Jones was promoted to the rank of major, 1 July 1920, and lieutenant colonel, 1 August 1935.

In 1939, because of a disagreement with senior Air Corps officers over military aviation doctrine, Lieutenant Colonel Jones requested a return to the Cavalry. He was promoted to the rank of colonel, Army of the United States, 16 November 1940, and colonel, United States Army, 1 February 1942.

Byron Jones graduated from the Army Industrial College in 1926, Command and General Staff School, 1927, and the Army War College, 1929.

Colonel Byron Q. Jones, United States Army

Colonel Jones was a leader in forming a mechanized cavalry and combined arms service. During World War II, he served in the Guadalcanal Campaign, and the staff of General Douglas MacArthur in Australia. He then held several assignments within the continental United States. He was hospitalized for lengthy periods several  times, and finally was discharged from the Army, 31 January 1944.

Colonel Byron Quinby Jones, United States Army (Retired), died at Walter Reed Army Hospital, 30 March 1959, at the age of 70 years. His remains were interred at the Arlington National Cemetery.

The Martin T was a two-place, single-engine biplane ordered as a trainer for the Signal Corps. Three were built and given serial numbers S.C.31–33. The airplane was a tractor configuration, with an engine and propeller at the front of the fuselage, rather than behind in a pusher configuration. The Martin T also had a wheeled tricycle undercarriage. Both of these features were relatively new and would become standard.
