13 July 1968: The first production General Dynamics FB-111A supersonic strategic bomber successfully completed a 30-minute maiden flight at Carswell Air Force Base, Fort Worth, Texas. The FB-111A differed from the F-111A fighter bomber with the substitution of a larger wing, originally designed for the F-111B, giving the bomber a 7 foot (2.134 meter) increase in wingspan. The landing gear was strengthened, the bomb bay enlarged, and it had more powerful engines.

Aardvark (Orycteropus afer)

The airplane’s very long nose earned the nickname “Aardvark,” but this did not become official until 1996.

67-0159 was delivered to the U.S. Air Force 4 September 1968 and assigned to the Air Force Flight Test Center, Edwards Air Force Base, California. (The first six production airplanes were used for flight testing.)

67-0159 was later converted to the F-111G configuration. In 1980 it was sent to the Sacramento Air Logistics Center to test weapons modifications and received a spectacular white and orange paint scheme. It was retired in 1990. 67-0159 is in the collection of the National Museum of the United States Air Force. It is on loan and now on display at the Aerospace Museum of California, Sacramento, California.

The General Dynamics FB-111A is a two-place, twin-engine, strategic bomber with variable-sweep wings, assigned to the Strategic Air Command. It is 73.54 feet (22.415 meters) long. The wingspan varies from a maximum 70.0 feet (21.336 meters) when fully extended, and a minimum 33.96 feet (10.351 meters) when swept fully aft. Overall height is 17.04 feet (5.194 meters).

The wings of the FB-111A have a total area of 550 square feet (51.10 square meters). When fully extended, the wings’ leading edges are swept aft to 16.0°. The angle of incidence at the root is +1° and -3° at the tip. There is 1.0° dihedral.

The Aardvark’s empty weight is 47,481 pounds (21,537 kilograms). Normal maximum takeoff weight is 116,115 pounds (52,669 kilograms), and the maximum overload takeoff weight is or 119,243 pounds (54,088 kilograms).

The aircraft is powered by two Pratt & Whitney TF30-P-107 engines. This is a two-spool axial-flow turbofan engine with afterburner. It has a 3-stage fan section, 13-stage compressor section (6 low- and 7 high-pressure stages) and 4-stage turbine (1 high- and 3 low-pressure stages). The -107 has a maximum continuous power rating of 10,800 pounds of thrust (48.041 kilonewtons) at 14,150 r.p.m., N2 (static thrust, at Sea Level), and a maximum power rating of 20,350 pounds (90.521 kilonewtons) at 14,550 r.p.m., N2 (45 minute limit) The T30-P-107 is 3 feet, 2.12 inches (0.968 meters) in diameter, 20 feet, 1.4 inches (6.132 meters) long,  and weighs 4,121 pounds (1,869 kilograms).

The FB-111A has an average cruise speed of 415–442 knots (478–509 miles per hour/769-819 kilometers per hour), depending on the mission profile. It’s maximum speed at 50,000 feet (15,240 meters) is 1,262 knots (1,452 miles per hour/2,337 kilometers per hour)—Mach 2.20. The bomber’s service ceiling varies from 50,390 feet to 56,380 feet (15,359–17,185 meters), again, depending on the mission profile. The maximum combat range is 4,920 nautical miles (5,662 statute miles/9,112 kilometers). The airplane can carry as many as six 600 gallon (2,271 liter) external tanks on underwing pylons. This gives the Aardvark a maximum ferry range of 4,313 nautical miles (4,963 statute miles/7,988 kilometers).

In addition to a prototype (63-9783, which was converted from the last production F-111A) General Dynamics built 76 FB-111A strategic bombers. With the introduction of the Rockwell B-1B Lancer, the FB-111As remaining in service were converted to F-111G tactical fighter bombers. They were retired by 2003.

The Royal Australian Air Force bought 15 of the F-111Gs. By 2007, these had also been taken out of service.

Mme Bastié’s airplane was a two-place, single-engine, Caudron C. 109 parasol-wing monoplane, F-AHFE, serial number 5804.1.

The C. 109 had a length of 6.440 meters (21 feet, 1.5 inches), wing span of 11.50 meters (37 feet, 8.8 inches) and height of 2.530 meters (8 feet, 3.6 inches). Its empty weight was 330 kilograms (727.525 pounds) and gross weight, 532 kilograms (1,173 pounds).

The standard C. 109 had a fuel capacity of 57 liters (15 U.S. gallons), and carried 15 litres (4 U.S. gallons) of lubricating oil for the engine. Its maximum speed was 120 kilometers per hour (75 miles per hour).

F-AHFE was powered by a naturally aspirated, air-cooled, 2,959.8 cubic centimeter (180.62 cubic inches) Société des Moteurs Salmson 9AD nine cylinder radial engine. The 9AD had a cylinder bore diameter of 69.9 millimeters (2.752 inches), and piston stroke of 85.7 millimeters (3.374 inches). It was rated at 45 ch at 2,000 r.p.m. The engine was 69.1 centimeters (27.20472 inches long and 63 centimeters (24.8031 inches) in diameter. It weighed 69.9 kilograms (154.1 pounds).

Airship R 34 over Pulham Airship Station, Norfolk, United Kingdom, 1919.

13 July 1919: The Royal Air Force rigid airship R 34 completed its two-way crossing of the Atlantic Ocean and at 6:57 a.m. landed at Pulham Airship Station, Norfolk, United Kingdom. The airship was under the command of Major George Herbert Scott, A.F.C., R.A.F. The total complement, including passengers, was 30 persons.

The return flight from Mineola, Long Island, New York took 73 hours, 3 minutes. According to records of the Fédération Aéronautique Internationale, the distance flown by R 34 on the return flight was 6,138 kilometers (3,814 miles).

This was the first “double crossing” by an aircraft. The round trip flight began at East Fortune Airship Station near Edinburgh, Scotland, on 2 July. The East-to-West crossing took 108 hours, 12 minutes.

Major Scott was appointed Commander of the Most Excellent Order of the British Empire.

During the return flight on of the airship’s five engines suffered a broken connecting rod which damaged the cylinder block. It could not be repaired.

R 34 was based on extensive study of the captured German Zeppelin, L-33. It was built for the Royal Naval Air Service by William Beardmore and Company, Inchinnan, Renfrewshire, Scotland, but with the end of World War I, the RNAS and Royal Flying Corps were merged to become the Royal Air Force. 643 feet long (196 meters), with a maximum diameter of 78 feet, 9 inches (24 meters), the dirigible had a total volume of 1,950,000 cubic feet (55,218 cubic meters). The airship had a light weight metal structure covered with doped fabric. Buoyancy was provided by 55,185 cubic meters (1,948,840 cubic feet) of gaseous hydrogen contained in 19 gas bags inside the airship’s envelope. R 34 had a gross lift capacity of 59 tons. Useful lift was 58,240 pounds (26,417 kilograms).

The airship was powered by five water-cooled, normally-aspirated, 15.395-liter (989.483-cubic-inch-displacement) Sunbeam Maori Mk.IV dual overhead cam (DOHC) 60° V-12 engines with four valves per cylinder. The Mk.IV’s cylinder bore had been increased from 100 millimeters to 110 millimeters (3.94 to 4.33 inches), resulting in a larger displacement than previous Maori variants. The Maori Mk.IV was a direct-drive engine which produced 275 horsepower at 2,000 r.p.m. Each engine turned a two-bladed, 17 foot diameter (5.182 meter) propellers through a remote gearbox with a 0.257:1 reduction. The two wing engines were equipped with reversible gearboxes. With the engines turning 1,800 r.p.m., the R 34 had a cruising speed of 47 knots (54 miles per hour/87 kilometers per hour) and consumed 65 gallons (246 liters) of fuel per hour.

13 July 1916: The 1st Aero Company, New York National Guard, under the command of Captain Raynal Cawthorne Bolling, became the first national guard unit to be mobilized into federal service in answer to the border crisis with Mexico. The unit trained at Mineola, New York, along the 2nd Aero Company, but did not deploy to the border.

Bolling was promoted to the rank of Colonel, Signal Corps, United States Army, 8 August 1917. Colonel Bolling was killed in action near Estrées-Deniécourt, France, 26 March 1918. As of that time, he was the highest-ranking U.S. officer to be lost during World War I. Bolling Field, the Air Corps station at Washington, D.C., was named in his honor.

The 1st Aero Company is the oldest Air National Guard unit. Today, it is 102nd Rescue Squadron, New York Air National Guard.
