23 March 1965: At 14:24:00 UTC, Gemini III was launched aboard a Titan II GLV  rocket from Launch Complex 19 at the Cape Kennedy Air Force Station, Cape Canaveral, Florida. Major Virgil I. (“Gus”) Grissom, United States Air Force, a Project Mercury veteran, was the Spacecraft Commander, and Lieutenant Commander John W. Young, United States Navy, was the pilot.

The purpose of the mission was to test spacecraft orbital maneuvering capabilities that would be necessary in later flights of the Gemini and Apollo programs. Gemini III made three orbits of the Earth, and splashed down after 4 hours, 52 minutes, 31 seconds. Miscalculations of the Gemini capsule’s aerodynamics caused the spacecraft to miss the intended splash down point by 50 miles (80 kilometers). Gemini III splashed down in the Atlantic Ocean, north east of the Turks and Caicos Islands. The recovery ship was USS Intrepid (CV-11).

Gus Grissom would later command the flight crew of Apollo 1. He was killed with his crew during the tragic fire  during a pre-launch test, 27 January 1967.

John Young served as Spacecraft Commander for Gemini 10, Command Module Pilot on Apollo 10, back-up commander for Apollo 13, commander Apollo 16, and back-up commander for Apollo 17. Later, he was commander of the maiden flight of the space shuttle Columbia STS-1 and again for STS-9 and was in line to command STS-61J.

The two-man Gemini spacecraft was built by the McDonnell Aircraft Corporation of St. Louis, the same company that built the earlier Mercury space capsule. The spacecraft consisted of a reentry module and an adapter section. It had an overall length of 19 feet (5.791 meters) and a diameter of 10 feet (3.048 meters) at the base of the adapter section. The reentry module was 11 feet (3.353 meters) long with a diameter of 7.5 feet (2.347 meters). The weight of the Gemini varied from ship to ship but was approximately 7,000 pounds (3,175 kilograms).

The Titan II GLV was a “man-rated” variant of the Martin SM-68B intercontinental ballistic missile. It was assembled at Martin’s Middle River, Maryland plant so as not to interfere with the production of the ICBM at Denver, Colorado. Twelve GLVs were ordered by the Air Force for the Gemini Program.

The Titan II GLV was a two-stage, liquid-fueled rocket. The first stage was 70 feet, 2.31 inches (21.395 meters) long with a diameter of 10 feet (3.048 meters). It was powered by an Aerojet Engineering Corporation LR87-7 engine which combined two combustion chambers and exhaust nozzles with a single turbopump unit. The engine was fueled by Aerozine 50, a hypergolic 51/47/2 blend of hydrazine, unsymetrical-dimethyl hydrazine, and water. Ignition occurred spontaneously as the components were combined in the combustion chambers. The LR87-7 produced approximately 430,000 pounds of thrust (1,912.74 kilonewtons). It was not throttled and could not be shut down and restarted. Post flight analysis indicated that the first stage engine of GLV-8 had produced an average of 461,080 pounds of thrust ( kilonewtons).

The second stage was 25 feet, 6.375 inches (7.782 meters) long, with the same diameter, and used an Aerojet LR91 engine which produced approximately 100,000 pounds of thrust (444.82 kilonewtons), also burning Aerozine 50. GLV-7’s LR91 produced an average of 102,735 pounds of thrust ( kilonewtons).

The Gemini III/Titan II GLV combination had a total height of 107 feet, 7.33 inches (32.795 meters) and weighed 340,000 pounds (156,652 kilograms) at ignition.

16 March 1966: At 16:41:02.389 UTC (12:41:02 p.m. Eastern Standard Time), forty years to the day after the launch of Dr. Robert Goddard’s first liquid-fueled rocket, Gemini VIII, with command pilot Neil Alden Armstrong and pilot David Randolph Scott, lifted off from Launch Complex 19 at the Cape Kennedy Air Force Station, Cape Kennedy, Florida, aboard a Titan II GLV booster. Their mission was to rendezvous and dock with an Agena Target Vehicle launched earlier aboard an Atlas rocket.

Gemini VIII entered a 86.3  × 146.7 nautical mile (99.3 × 168.8 statute miles/160 × 271.7 kilometers) elliptical orbit. The spacecraft was traveling at 17,549 miles per hour (28,242 kilometers per hour).

The docking, the first ever of two vehicles in Earth orbit, was successful, however after about 27 minutes the combined vehicles begin rolling uncontrollably. The Gemini capsule separated from the Agena, and for a few minutes all seemed normal. But the rolling started again, reaching as high as 60 r.p.m.

The astronauts were in grave danger. Armstrong succeeded in stopping the roll but the Gemini’s attitude control fuel was dangerously low.

The pilots’ report reads:

     Shortly after sending encoder command 041 (recorder ON), roll and yaw rates were observed to be developing. No visual or audible evidence of spacecraft thruster firing was noted, and the divergence was attributed to the GATV.

     Commands were sent to de-energize the GATV ACS, geocentric rate, and horizon sensors, and the spacecraft Orbital Attitude and Maneuver System (OAMS) was activated.

     The rates were reduced to near zero, but began to increase upon release of the hand controller. The ACS was commanded on to determine if GATV thruster action would help reduce the angular rates. No improvement was noted and the ACS was again commanded off. Plumes from a GATV pitch thruster were visually observed, however, during a period when the ACS was thought to be inactivated.

     After a period of relatively stable operation, the rates once again began to increase. The spacecraft was switched to secondary bias power, secondary logics, and secondary drivers in an attempt to eliminate possible spacecraft control-system discrepancies. No improvement being observed, a conventional troubleshooting approach with the OAMS completely de-energized was attempted, but subsequently abandoned because of the existing rates.

     An undocking was performed when the rates were determined to be low enough to precluded any recontact problems. Approximately a 3 ft/sec velocity change was used to effect separation of the two vehicles.

     Angular rates continued to rise, verifying a spacecraft control-system problem. The hand controller appeared to be inactive. The Reentry Control System (RCS) was armed and, after trying ACME-DIRECT and then turning off all OAMS control switches and circuit breakers, was found to be operative in DIRECT-DIRECT. Angular rates were reduced to small values with the RCS B-ring. Inspection of the OAMS revealed that the no. 8 thruster had failed to open. Some open Attitude Control and Maneuver Electronics (ACME) circuit breakers probably accounted for the inoperative hand controller noted earlier. All yaw thrusters other than number 8 were inoperative. Pitch and roll control were maintained using the pitch thrusters. . .

      All four retrorockets fired on time. . . .

The mission was aborted and the capsule returned to Earth after 10 hours, 41 minutes, 26.0 seconds, landing in the Pacific Ocean at N. 25° 12′, E. 136° 05′. U.S. Air  Force pararescue jumpers (“PJs”) parachuted from a Douglas C-54 transport and attached a flotation collar to the Gemini capsule. The astronauts were recovered by the Gearing-class destroyer USS Leonard F. Mason (DD-852), about three hours later..

The two-man Gemini spacecraft was built by the McDonnell Aircraft Corporation of St. Louis, Missouri, the same company that built the earlier Mercury space capsule. The spacecraft consisted of a series of cone-shaped segments forming a reentry module and an adapter section. It had an overall length of 18 feet, 9.84 inches (5.736 meters) and a maximum diameter of 10 feet, 0.00 inches (3.048 meters) at the base of the equipment section. The reentry module was 11 feet (3.353 meters) long with a maximum diameter of 7 feet, 6.00 inches (2.347 meters). The Gemini re-entry heat shield was a spherical section with a radius of 12 feet, 0.00 inches (3.658 meters). The weight of the Gemini spacecraft varied from ship to ship. Gemini VIII weighed 8,351.31 pounds (3,788.09 kilograms) at launch. Spacecraft 8 was shipped from the St. Louis factory to Cape Kennedy on 2 January 1966.

12 March 1967

12 March 1967: McDonnell Aircraft Corporation, St. Louis, Missouri, delivered the 2,000th F-4 Phantom II to the United States Air Force. F-4D-30-MC 66-7533, c/n 2062, was assigned to the 40th Tactical Fighter Squadron, 33rd Tactical Fighter Wing, at Eglin Air Force Base, Florida.

On 26 May 1967, the personnel and equipment of the 40th TFS were transferred to the 8th Fighter Wing based in Thailand. The aircraft were deployed across the Pacific Ocean, 26–28 May, with flights to Hickam Air Force Base, Honolulu, Hawaii; Anderson Air Force Base, Guam; and Ubon-Rachitani Royal Thai Air Force Base, Thailand. On 25 July 1967, an additional twenty F-4Ds arrived at Ubon RTAFB, having been transferred from the 4th TFS. 66-7533 was included in this later group of Phantoms.¹

On 19 September 1967, the 2,000th Phantom II was being flown by Major Lloyd Warren Boothby and 1st Lieutenant George H. McKinney, Jr., of the 435th Tactical Fighter Squadron. Following a Rolling Thunder attack on railroad sidings at Trung Quang, about 10 miles (16.1 kilometers) north of Phúc Yên, 66-7533 was hit in the right wing by a 57 mm anti-aircraft cannon shell. The airplane was badly damaged but “Boots” Boothby fought to keep it under control for as long as possible. Finally, he and McKinney were forced to eject, having come within about 35 miles (56.3 kilometers) of their base.

At the time of its loss, 66-7533 had accumulated 155 flight hours on its airframe (TTAF).

Distinguished Flying Cross

For their airmanship in trying to save their airplane, Major Boothby and Lieutenant McKinney were each awarded the Distinguished Flying Cross, which was presented to them by President Lyndon B. Johnson, 23 December 1967, in a pre-dawn ceremony at Korat Royal Thai Air Force Base.

Lieutenant McKinney is quoted in USAF F-4 Phantom II MiG Killer 1965–1968:

“In the hail of AAA over the target seven miles north of Hanoi on that day was a ‘Golden BB’ which opened a three-foot hole in the Phantom II’s right wing, froze the right spoiler full up, immediately drained two of the three hydraulic systems and generally turned the day to crap! I mumbled an egress heading (and a few dozen prayers) while ‘Boots’ used every increment of incredible aviation instincts, honed by countless hours at the edge of the envelope, to keep the F-4 airborne and headed away from the ‘Hanoi Hilton.’ Doing so required full manual depression of the left rudder pedal, and holding the stick within one inch of the left limit of travel.

“Despite the physical exertion, coupled with the precise touch necessary to remain airborne as the Black River receded behind the crippled Phantom II and rescue became at least a possibility, ‘Boots” managed to announce to the world on ‘Guard’ channel that they had so many warning lights lit up that it ‘looks like we’ve won a free game at the arcade.’ “

USAF F-4 Phantom II MiG Killer 1965–1968, by Peter E. Davies, Osprey Publishing, 2004, at Page 75.

[A number of sources state that Lt. McKinney did not survive the ejection, but this is incorrect. Both pilots were rescued by helicopter. McKinney went on to earn credit for 2.5 kills as a Weapons System Officer, and returned for another combat tour as an F-4 aircraft commander.]

Boothby
Lieutenant Colonel Lloyd Warren Boothby, United States Air Force

WASHINGTON (AFPN) — I’d hate to see an epitaph on a fighter pilot’s tombstone that says, “I told you I needed training”. . . How do you train for the most dangerous game in the world by being as safe as possible? When you don’t let a guy train because it’s dangerous, you’re saying, “Go fight those lions with your bare hands in that arena, because we can’t teach you to learn how to use a spear. If we do, you might cut your finger while you’re learning.” And that’s just about the same as murder. —Lt. Col. Lloyd “Boots” Boothby, April 17, 1931, to Nov. 26, 2006

That quote may seem a little extreme, but Colonel Boothby was referring to the Air Force’s urgent need to improve fighter tactics training, balanced against safety, but not at the expense of effectiveness.

Colonel Boothby, who passed away Nov. 26, was an experienced combat pilot and an academic instructor in the 57th Fighter Weapons Wing in the early 1970s. He looked at the Air Force’s declining kill ratio from Korea to Vietnam which was 2.4 to 1 in Vietnam compared to 8 to 1 in the Korean War. He led the effort to fix it. This involved several key steps, starting with a thorough analysis of the engagements over Vietnam.

Colonel Boothby led a series of studies at the Tactical Fighter Weapons Center, which were part of Project Red Baron, examining each of the war’s air-to-air battles. While the subsequent reports noted many accomplishments and even more lessons learned, they highlighted several significant trends. The colonel’s team discovered that pilots of multi-role fighters tended to have such a diverse range of missions that they seldom had a chance to master air combat tactics. They also noted pilots who were shot down rarely saw the enemy aircraft or even knew they were being engaged.

Additionally, few U.S. pilots, before flying into combat, had any experience against the equipment, tactics or capabilities of the enemy’s smaller, highly maneuverable fighters.

In short, the Red Baron Reports called for “realistic training (that) can only be gained through study of, and actual engagements with, possessed enemy aircraft or realistic substitutes.”

Based on this report and Colonel Boothby’s persuasiveness to get himself and Capt. Roger Wells access to an intelligence organization’s restricted collection of Soviet equipment, training manuals and technical data, they developed the dissimilar air combat training, or DACT, program to meet the Tactical Air Command’s initiative of “Readiness through Realism.”

Under the DACT program, Air Force officials had some T-38s painted with Soviet-style paint schemes and flew them based on adopted Soviet tactics.

Because of his combat experience, academic instructor background, and involvement in Project Red Baron and in developing the DACT program, Colonel Boothby served as the first aggressor squadron’s commander when the 64th Fighter Weapons Squadron activated Oct. 15, 1972.

As an instructor, Colonel Boothby proved himself an effective teacher who relished the attention of his captive audience. Ever-animated and quick with a joke or “fighter” story to make a point, he told the pilots he was instructing what they needed to know to succeed. These qualities ensured his students’ attention remained spellbound and eager.

One former student recalled one of the colonel’s more popular attention steps. In typical fighter pilot stance, using his hands to represent a dogfight, he would spray lighter fluid from his mouth across his right hand (palming a lighter at the time) and literally flame the left hand and wristwatch bogie. He generally walked away with a few singed hairs on his hand, but his students received a magnificent visual demonstration of the seriousness of air combat.

Such object lessons ensured this charismatic instructor’s students learned and retained the knowledge they might need to save their lives one day.

Upon learning of Colonel Boothby’s death recently, Air Force Chief of Staff Gen. T. Michael Moseley noted:

“He. . . had an impact on how we do business and how we think about this air combat work. Folks out there like [Colonel Richard] Moody Suter and Boots Boothby have left a true legacy. I know one Texas public school-educated, land grant college graduate, F-15 weapons officer, Fighter Weapons Instructor Course instructor and ex-57th Wing commander who has certainly benefited from folks like this.”

MAJOR JOHN R. PARDO, UNITED STATES AIR FORCE

Major John R. Pardo distinguished himself by gallantry in connection with military operations against an opposing armed force over North Vietnam on 10 March 1967. On that date, Major Pardo was flying as the pilot of the lead element on the return from a 1,000 mile flight in which heavy flak damage was encountered. He noticed that his wingman’s aircraft was in trouble and was advised that the aircraft was extremely low on fuel. Realizing that the wingman’s aircraft would not make it out of North Vietnam, Major Pardo implemented maneuvers to literally push the aircraft across the border. The attempt was successful and consequently allowed the crew to avoid becoming prisoners of war. By his gallantry and devotion to duty, Major Pardo has reflected great credit upon himself and the United States Air Force.

28 February 1966

The Flight Crew of Gemini IX, left to right, Commander Elliot McKay See, Jr., United States Navy, and Captain Charles A. Bassett II, U.S. Air Force.

28 February 1966: The primary and back up flight crews of Gemini IX flew from Houston to St. Louis where they planned to visit the McDonnell Aircraft Corporation, where the spacecraft was being built. They flew aboard two Northrop T-38A Talon supersonic trainers which NASA used for proficiency training.

The lead aircraft, NASA 901, was flown by Commander Elliot McKay See, Jr., United States Navy Reserve. See was designated as the Command Pilot for Gemini IX. Captain Charles Arthur (“Charlie”) Bassett II, U.S. Air Force, Pilot, Gemini IX, was in the rear cockpit. NASA 901 was a Northrop T-38A-50-NO Talon 63-8181 (Northrop serial number N.5528).

Northrop T-38A-50-NO Talon 63-8181

The second T-38, NASA 907, was flown by Lieutenant Colonel Thomas P. Stafford, U.S. Air Force, and Lieutenant Commander Eugene A. Cernan, U.S. Navy.

Weather at Lambert-St. Louis Municipal Airport was poor with low clouds and limited visibility in rain and snow. Lambert Field weather at 8:25 a.m. was: sky partially obscured, measured ceiling 800 feet (244 meters) broken, 1,500 feet (457 meters) overcast, visibility 1½ miles (2.4 kilometers) in light rain, light snow, and fog.

Elliot See flew an ILS instrument approach and broke out of the clouds properly aligned with the runaway, but was too high to make a landing. He requested a visual, circling approach. The T-38 entered a 360° turn to the southeast at approximately 500 feet (152 meters). During the circling approach, Stafford, in NASA 907, lost sight of See’s T-38 and executed a missed approach. As his airplane came around to line up for the runway, See radioed that he had the runway in sight, but, at 8:58 a.m., NASA 901 struck the top of McDonnell’s Building 101 and crashed.

The wreck immediately caught fire and both See and Bassett were killed. Sixteen people on the ground were injured.

The accident investigation board found that at approximately 3 seconds before the crash, Elliot See had apparently tried to climb away. The T-38’s angle of bank was significantly reduced and afterburner was selected.

The T-38 was the world’s first supersonic flight trainer. The Northrop T-38A Talon is a pressurized, two-place, twin-engine, jet trainer. Its fuselage is very aerodynamically clean and uses the “area-rule” (“coked”) to improve its supersonic capability. It is 46 feet, 4.5 inches (14.135 meters) long with a wingspan of 25 feet, 3 inches (7.696 meters) and overall height of 12 feet, 10.5 inches (3.924 meters). The one-piece wing has an area of 170 square feet (15.79 square meters). The leading edge is swept 32°. The airplane’s empty weight is 7,200 pounds (3,266 kilograms) and maximum takeoff weight is approximately 12,700 pounds (5,761 kilograms).

The T-38A is powered by two General Electric J85-GE-5 turbojet engines. The J85 is a single-shaft axial-flow turbojet engine with an 8-stage compressor section and 2-stage turbine. The J85-GE-5 is rated at 2,680 pounds of thrust (11.921 kilonewtons), and 3,850 pounds (17.126 kilonewtons) with afterburner. It is 108.1 inches (2.746 meters) long, 22.0 inches (0.559 meters) in diameter and weighs 584 pounds (265 kilograms)

The T-38A has a maximum speed of Mach 1.08 (822 miles per hour/1,323 kilometers per hour) at Sea Level, and Mach 1.3 (882 miles per hour/1,419 kilometers per hour) at 30,000 feet (9,144 meters). It has a rate of climb of 33,600 feet per minute (171 meters per second) and a service ceiling of 55,000 feet (16,764 meters). Its range is 1,140 miles (1,835 kilometers).

Between 1959 and 1972, 1,187 T-38s were built at Northrop’s Hawthorne, California, factory. As of 4 September 2018, 546 T-38s remained in the U.S. Air Force active inventory. The U.S. Navy has 10, and as of 30 October 2018, the Federal Aviation Administration reports 29 T-38s registered to NASA.
