After four years of planning and preparation, the National Aeronautics and Space Administration (NASA) and the Federal Aviation Administration (FAA) intentionally crashed a Boeing 720 airliner to test an experimental fuel additive intended to reduce post-crash fires, and to assess passenger survivability. An anti-misting agent was added to standard commercial JP-5 jet fuel to create AMK, or “Anti-Misting Kerosene.” The airliner’s fuel tanks were filled with the AMK mixture, totaling 16,060 gallons (10,794 liters). Instrumented crash test dummies were placed in the passengers seats.

NASA 833, the Boeing 720-027 airliner, FAA registration N833NA, was a remotely-piloted aircraft. NASA test pilot Fitzhugh Lee (“Fitz”) Fulton, Jr., flew NASA 833 from a ground station, the NASA Dryden Remotely Controlled Vehicle Facility. More than 60 flights had been made prior to the actual test.

The test was planned so that the airliner would make a shallow 3.8° approach to a prepared runway on the east side of Rogers Dry Lake at Edwards Air Force Base. It was to land on its belly in a wings-level attitude, then slide into a group of barriers, called “rhinos,” which would slice open the wing tanks. The fuselage and passenger cabin would remain intact. NASA and the FAA estimated that this would be “survivable” for all occupants.

Just before touchdown, the Boeing 720 entered a "Dutch roll." The airliner's nose yawed to the left and the left wing dipped, striking the ground sooner than was planned. All four engines are still at full throttle. NASA 833 is to the right of the runway center line. (NASA)

As the Boeing 720 descended on its Final Approach, its nose yawed to the right and the airplane went to the right of the runway center line. It then yawed back to the left and entered an out-of-phase oscillation called a “Dutch roll.” The decision height to initiate a “go-around” was 150 feet (45.7 meters) above the surface of the lake bed. Fitz Fulton thought he had enough time to get NASA 833 back on the center line and committed to the test landing. However, the Dutch roll resulted in the airliner’s left wing impacting the ground with the inboard engine on the left wing (Number Two) just to the right of the center line.

According to the test plan, all four of the airliner’s engines should have been brought to idle, but they remained at full throttle. The left wing’s impact yawed the airliner to the left and, rather than the fuselage passing through the rhino barriers undamaged, the passenger compartment was torn open. Another rhino sliced into the Number Three engine (inboard, right wing), opening its combustion chamber. With the fuel tanks in the wings ruptured, raw fuel was sprayed into the engine’s open combustion chamber which was still at full throttle.

As the airliner slides through the "rhino" barriers, they rip open the fuel tanks, the Number Three engine and the passenger compartment. The raw fuel immediately ignited. (NASA)

The raw fuel ignited and exploded into a fireball. Flames immediately entered the passenger compartment. As the 720 slid on the runway it continued to rotate left and the right wing broke off though the fuselage remained upright.

As the right wing came off the ruptured fuel tanks emptied most of the raw fuel directly into the fireball.

Over an hour was required to extinguish the flames. The test of the flame-reducing fuel additive was a complete failure. Test engineers estimated that 25% of the occupants might have survived the crash, however, it was “highly speculative” that any could have escaped from the burning, smoke-filled passenger compartment.

Fitz Fulton, 1942 (The Cohiscan)

Fitzhugh Lee Fulton, Jr., was born at Blakely, Georgia, 6 June 1925, the first of two sons of Fitzhugh Lee Fulton, a merchant seaman, and Manila Fulton. He attended Columbus High School, Columbus Georgia, graduating in 1942. He entered College at Alabama Polytechnic Institute (now known as Auburn University) and the University of Oklahoma. He was awarded a bachelor of arts degree from Golden Gate University, San Francisco, California.

Fulton entered the U.S. Army Air Corps in 1943, and was trained as a pilot. He married Miss Erma I. Beck at Tucson, Arizona, 16 December 1945. They would have three children.

Following World War II, participated in Operation Crossroads, the atomic bomb tests at Bikini Atoll, July 1946. Lieutenant Fulton flew the Douglas C-54 Skymaster four-engine transport during the Berlin Airlift, making 225 sorties, and then the Douglas B-26 Invader light attack bomber during the Korean War.

At Edwards Air Force Base, he flew the B-52 “mother ships” for the X-15 Program. He flew the North American XB-70A Valkyrie faster than Mach 3. When Fulton retired from the Air Force in 1966, he was a lieutenant colonel assigned as Chief of Bomber and Transport Test Operations.

Fitz Fulton continued as a research test pilot for NASA, flying as project pilot for the YF-12A and YF-12C research program. He flew all the early test flights of the NASA/Boeing 747 Shuttle Carrier Aircraft and carried the space shuttle prototype, Enterprise. By the time he had retired from NASA, Fulton had flown more than 16,000 hours in 235 aircraft types.

NASA 833 (c/n 18066) was ordered by Braniff Airways, Inc., as N7078, but the sale was not completed. The airplane first flew 5 May 1961 and it was delivered to the Federal Aviation Administration as a test aircraft one week later, 12 May 1961, registered N113. A few years later the identification was changed to N23, then back to N113, and then once again to N23. In 1982, the Boeing 720 was transferred to NASA to be used in the Controlled Impact Demonstration. At this time it was registered as N2697V. A final registration change was made to N833NA.

The Boeing 720 was a variant of the Model 707, intended for short to medium range flights. It had 100 inches (2.54 meters) removed from the fuselage length and improvements were made to the wing, decreasing aerodynamic drag, though it retained the span of the 707.

The Boeing 720 was powered by four Pratt & Whitney Turbo Wasp JT3C-7 turbojet engines, a civil variant of the military J57 series. The 720B was equipped with the more efficient P&W JT3D-1 turbofan engines. The JT3C-7 was a “two-spool” axial-flow engine with a 16-stage compressor (9 low- and 7 high-pressure stages), 8 combustion tubes, and a 3-stage turbine (1 high- and 2 low-pressure stages). It was rated at 12,030 pounds of thrust (53.512 kilonewtons) for takeoff. The JT3D-1 was a dual axial-flow turbofan engine, with a 2-stage fan section 13-stage compressor (6 low- and 7 high pressure stages), 8 combustion chambers and a 4-stage turbine (1 high- and 3 low-pressure stages). This engine was rated at 14,500 pounds of static thrust (64.499 kilonewtons) at Sea Level, and 17,000 pounds (75.620 kilonewtons), with water injection, for takeoff (2½ minute limit). Almost half of the engine’s thrust was produced by the fans. Maximum engine speed was 6,800 r.p.m. (N1) and 10,200 r.p.m. (N2). It was 11 feet, 4.64 inches (3.471 meters) long, 4 feet, 5.00 inches (1.346 meters) wide and 4 feet, 10.00 inches (1.422 meters) high. It weighed 4,165 pounds (1,889 kilograms). The JT3C could be converted to the JT3D configuration during overhaul.

The maximum cruise speed of the Boeing 720 was 611 miles per hour (983 kilometers per hour) and maximum speed was 620 miles per hour (1,009 kilometers per hour). The range at at maximum payload was 4,370 miles (7,033 kilometers).

Boeing built 154 720 and 720B airliners from 1959 to 1967.

1909: De Havilland No. 1

De Havilland No. 1 at Seven Barrows, Hampshire, 1909. (BAE Systems)

History has forgotten the actual date—perhaps because he was no one of  any importance at the time—but one day in the Fall or Winter of 1909, Geoffrey de Havilland, an automotive engineer, took off from Seven Barrows, Hampshire, England, in an airplane of his own design. Today, that airplane is known as the de Havilland No. 1.

De Havilland had borrowed £1,000 from his grandfather, and together with fellow engineer Francis Trounson Hearle, built an airplane.

The de Havilland No. 1 was a single-engine, single-place, three-bay biplane in a pusher configuration. It had a forward elevator (canard), and an aft-mounted rudder and adjustable horizontal stabilizer. Ailerons were mounted on the upper wing.

The structure of the airplane was built of American white wood (which proved to be a poor choice) and was braced with steel wires. The fuselage was an open girder tapered at each end. It was built of 1½″ × 1½″ (3.81 × 3.81 centimeters) longitudinals with 1¼″ × ¼″ (3.175 × 0.635 centimeter) cross braces from the engine aft. It had a cross section at the widest point of 2′4″ x 2′0″ (0.711 × 0.610 meters). The lower longitudinals were reinforced with angled steel beneath the engine

The de Havilland was 29 feet, 0 inches (8.839 meters) long with a wingspan of 36 feet, 0 inches (10.973 meters). Both wings had a chord of 6 feet, 0 inches (1.829 meters) and the vertical gap was also 6 feet, 0 inches. The wings were not staggered. The airplane weighed 850 pounds ( kilograms).

Three-view illustration of the de Havilland No. 1. (FLIGHT, 9 April 1910, Page 267)

The DH.1 was powered by a single water-cooled, normally-aspirated, 302.18 cu in (4.95 liters) de Havilland-Iris four-cylinder horizontally-opposed overhead valve engine, designed by Geoffrey de Havilland and built by the Iris Motor Co., Willesden, London. The engine produced 40 horsepower at 1,050 r.p.m., and 52 horsepower at 1,500 r.p.m. In running condition, it weighed 230 pounds (104 kilograms) including a 30 pound (14 kilogram) flywheel. The de Havilland-Iris used cast iron cylinders with a copper water jacket. The two-throw crankshaft was prone to failures after a only few hours of operation.

The engine was mounted in the airframe with its crankshaft at a right angle to the direction of flight. It drove two 7 foot, 4 inch (2.235 meter) diameter counter-rotating propellers made of aluminum. The paddle-type blades could be adjusted for pitch before flight. Tubular shafts drove through 90° bevel gears and turned the propellers at 550–600 r.p.m.

And it should be added that the past tense has advisably been used in the foregoing paragraph, inasmuch as the first free flight of the machine terminated in almost complete wreckage. The first time that it left the ground it did so after travelling some 40 yards on a downward slope under its own power; it then rose at a rather steep angle, which was corrected by the pilot; and almost immediately afterwards—about 35 yards from the take-off—the left main plane doubled up, causing the machine to fall heavily forward and to the left. Luckily, Mr. de Havilland himself was not hurt, but it will be observed from some of the photographs which we reproduce that the machine as such, apart from the propelling mechanism, the rudder, and the tail, was, for all practical purposes, virtually annihilated by the fall.

(Flight No. 68, Vol. II, No. 16, 16 April 1910, Page 286)

The airplane’s engine was salvaged and reused in de Havilland No. 2.

30 November 1951: Major George Andrew Davis, Jr., commanding the 334th Fighter Interceptor Squadron, 4th Fighter Interceptor Wing, based at Kimpo Air Base, South Korea, led a patrol of eight North American Aviation F-86 Sabre fighters near the Yalu River, dividing Korea from China. This area was known as “MiG Alley” because of the large numbers of Russian-built Mikoyan-Gurevich MiG-15 fighters which were based on the Chinese side of the river.

At about 4:00 p.m., the American pilots saw a group of nine Russian Tupolev Tu-2 twin-engine medium bombers, escorted by 16 Lavochkin La-11 fighters. The bombers were on a mission to attack Taewa-do Island.

Davis led his fighters in an attack, making four firing passes on the bombers. He shot down three of the Tu-2s, when one of his pilots, Captain Raymond O. Barton, Jr., called for help. Barton’s Sabre, F-86A-5-NA 49-292, was under attack by 24 MiG-15s which had arrived to reinforce the bombing mission. Barton later described the battle:

“. . . I broke left again and was going to make another pass when I checked my ‘six o’clock’ to clear for my wingman. All of the sudden the SOB started shooting at me, and only then did I realize that I had attracted far more than one MiG. I turned into them. . . I called for help, and the only response I got was from my roommate, Major George Davis. I’ll never forget his reply. ‘I don’t have enough fuel left either but I’m on the way.’  All the MiGs except one had left the area. I had a huge hole where my left fuel cap had been, but I was still flying. When George reached me, he asked me to make a couple of identifying turn reversals. I reluctantly did and he shot that SOB right off my butt.”

Distinguished Service Cross

Major Davis escorted Captain Barton back to their base, landing with just five gallons of fuel remaining in his tanks.

For his actions, Major George A. Davis, Jr., was awarded the Distinguished Service Cross. (He had also been awarded a DSC in World War II.)

The President of the United States of America, under the provisions of the Act of Congress approved July 9, 1918, takes pride in presenting the Distinguished Service Cross (Air Force) (Posthumously) to Major George Andrew Davis, Jr. (AFSN: 0-671514/13035A), United States Air Force, for extraordinary heroism in connection with military operations against an armed enemy of the United Nations while serving as Squadron Commander, 334th Fighter-Interceptor Squadron, 4th Fighter-Interceptor Wing, FIFTH Air Force, on 27 November 1951, during an engagement with enemy aircraft near Sinanju, Korea. While leading a group formation of thirty-two F-86 aircraft on a counter air mission, Major Davis observed six MIG-15 aircraft headed southward above the group. With exemplary leadership and superior airmanship, he maneuvered his forces into position for attack. Leading with great tactical skill and courage, Major Davis closed to 800 feet on a MIG-15 over Namsi. He fired on the enemy aircraft, which immediately began burning. A few seconds later, the enemy pilot bailed out of his aircraft. Continuing the attack on the enemy forces, Major Davis fired on the wingman of the enemy flight, which resulted in numerous strikes on the wing roots and the fuselage. As Major Davis broke off his relentless attack on this MIG-l5, another MIG-15 came down on him. He immediately brought his aircraft into firing position upon the enemy and after a sustained barrage of fire, the enemy pilot bailed out. Although low on fuel, he rejoined his group and reorganized his forces to engage the approximate 80 enemy aircraft making the attack. Against overwhelming odds, Major Davis’ group destroyed two other MIG-15 aircraft, probably destroyed one and damaged one other. Major Davis’ aggressive leadership, his flying skill and devotion to duty contributed invaluable to the United Nations’ cause and reflect great credit on himself, the Far East Air forces and the United States Air Force.

Having shot down four enemy aircraft during one fighter patrol, Davis’ score of aerial victories during his short time in Korea rose to six, making him an ace for the Korean War. Davis had previously shot down seven enemy airplanes during World War II with his Republic P-47 Thunderbolt. Davis was the first American pilot to become an ace in two wars.

George Davis would soon be credited with another eight victories, making him the leading American ace up to that time. He was killed in action 10 February 1952 in an air battle for which he would be awarded the Medal of Honor.

Raymond Oscar (“R.O.”) Barton, Jr., was born at Omaha, Nebraska, 8 March 1927. he was the son of Major General Raymond O. Barton and Clare Fitzpatrick Barton. He was a 1948 graduate of the United States Military Academy at West Point, New York. Barton flew 100 combat missions during the Korean War. He is credited with three MiG 15s destroyed and another 7 damaged. R.O. Barton died at Augusta, Georgia, in 2003.

30 November 1944: In another iconic photograph from World War II, this Boeing B-17 Flying Fortress, B-17G-75-BO 43-37877, of the 836th Bombardment Squadron (Heavy), 487th Bombardment Group (Heavy), was hit by anti-aircraft artillery just after bomb release near Merseburg, Sachsen-Anhalt, Germany, at 1314 GMT, 30 November 1944.

43-37877 was crewed by 1st Lieutenant Lloyd W. Kersten, Pilot; 1st Lieutenant Henry E. Gerland, Co-Pilot; 1st Lieutenant James Hyland, Navigator; 1st Lieutenant Warren R. Ritchhart, Bombardier; Technical Sergeant Arnold R. Shegal, Flight Engineer/Gunner; Staff Sergeant Everett S. Morrison, Ball Turret Gunner; Staff Sergeant Joseph M. Miller, Gunner; Staff Sergeant Maurice J. Sullivan, Tail Gunner.

The B-17 crashed near Halle, Sachsen-Anhalt. Seven of the crew were killed. Two, Lieutenants Hyland and Richart, were captured and held as prisoners of war.

43-37877 was built by the Boeing Airplane Company at its Plant II, south of downtown Seattle, Washington. It was delivered to the United Air Lines Modification Center at Cheyenne, Wyoming, on 31 May 1944. After completion of modifications, on 12 June the B-17 was flown to Hunter Army Air Field at Savannah, Georgia, and then on 3 July, to Dow Army Air Field at Bangor, Maine, where it was positioned to be ferried across the north Atlantic Ocean to England.

On 19 June the new bomber was assigned to the 379th Bombardment Group (Heavy), which was based at RAF Kimbolton (U.S. Army Air Force Station 117), west of Huntingdon in Cambridgeshire. Then on 4 July 1944, B-17G 43-32877 was reassigned to the 836th Bombardment Squadron (Heavy), 487th Bombardment Group (Heavy) at RAF Lavenham (AAF-137), north of Sudbury in Suffolk, England..

43-37877 was not camouflaged. It was marked with a white letter P in a black square on the vertical fin, indicating the 487th Bomb Group, along with a partial serial number, 333787. The side of the fuselage was marked 2G ✪ E, indicating that it was assigned to the 836th Bomb Squadron. The wing tips, vertical fin and rudder, and horizontal stabilizer and elevators were painted yellow.

Focke-Wulf Fw 200 S-1 D-ACON

28–30 November 1938: The first prototype Focke-Wulf Fw 200 Condor, D-ACON, flew from Berlin, Germany, to Tokyo, Japan, to demonstrate the long-distance capabilities of the new civil airliner.

The Condor’s flight crew was the same as that which had made a previous Berlin–New York transatlantic flight, 10–11 August 1938. Deutsche Luft Hansa Kapitän Alfred Henke, Hauptmann Rudolf Freiherr von Moreau, of the Luftwaffe, co-pilot; Paul Dierberg, flight engineer; Walter Kober, radio operator. Senior radio operator Georg Khone was an additional crew member. (He had originally been scheduled to make the transatlantic flight.) For this flight there  was a single passenger, verkaufsdirecktor (sales director) Heinz Junge.¹

The Condor took off from Flugplatz Berlin-Staaken at 3:53 p.m., on 28 November, and flew to Basra, Kingdom of  Iraq. The Great Circle distance between the two cities is 2,305 miles (3,710 kilometers)

After refueling, the Fw 200 took off for its next destination, Karachi Air Port in the Sindh province of the British India (now, Pakistan). The distance for the second leg of the journey was 1,238 miles (1,993 kilometers).

From Karachi, Captain Henke and his crew flew on to the city of Hà Nội, in the Protectorate of Tonkin, Indochine française. The Great Circle distance for the third leg is 2,480 miles (3,991 kilometers).

The final segment was from Hanoi to Tokyo, Japan, a distance of 2,281 miles (3,671 kilometers). The Condor arrived at Tachikawa Airfield in the western part of Tokyo at 10:40 p.m., 30 November.

The total elapsed time for the journey was 46 hours, 18 minutes, 19 seconds. The actual flight time was 42 hours, 00 minutes. The Condor’s average speed from Berlin to Tokyo was 198.308 kilometers per hour (123.223 miles per hour).

Captain Henke and his crew established a Fédération Aéronautique Internationale (FAI) World Record for Speed Over Courses for the journey from Berlin to Hanoi, with an average speed of 243.01 kilometers per hour (150.999 miles per hour).² The total elapsed time, Berlin–Hanoi, was 34 hours, 17 minutes, 27 seconds.

D-ACON arrival Tokyo 30 Nov 22:34:24 (Arawasi)

The Condor’s crew was received by Emperor Hirohito.

The Japanese airline Nihon Koku Yuso Kabushiki Kaisha (NYKK) agreed to buy five Focke-Wulf Fw 200 airliners. The Imperial Japanese navy expressed interest in a maritime patrol version.

The Associated Press news agency reported:

Nazi Airmen Start Berlin to Tokyo Hop

     Berlin, Nov. 28—(AP)—A fast four-motored Focke-Wulf Condor plane took off today for Tokyo with a crew of five and one passenger, to show the orient, especially Japan, Germany’s latest achievements in airplane building.

     With only three stops scheduled en route—at Basra, Iraq; Karachi, India, and Hanoi, French Indo-China—it was expected that the entire distance of 9,300 miles would be covered in from 50 to 55 hours.

     Lufthansa officials, however, declared no record would be sought. They said the flight was intended to return the visit of Japan’s “Divine Wind,” which flew here in April, 1937.

     But no secret was made of the fact that Japan has been negotiating for purchase of German commercial planes, for which reason the big Condor was chosen to show its paces.

     Officials said it would return by way of Batavia, capital of the Netherlands East Indies, and Amsterdam in order to show the Royal Dutch air line that its time of six days between those points can be lowered to four.

     The Germans may make a side -trip to Manchoukuo, where purchase of German planes is also being negotiated.

     It was expected they would be back in Berlin by December 17.

GERMAN FLYERS REACH TOKIO IN 47 HOUR FLIGHT

(Chicago Tribune Press Service.)

     TOKIO, Nov. 30.—Completing an 8,375 mile flight from Berlin to Tokio in 46 hours and 41 minutes, five German airmen and one passenger landed their plane at 10:35 o’clock tonight on Tachikawa army airfield on the outskirts of Tokio. The plane, a four-motor Focke-Wulf Condor capable of carrying twenty-six passengers, left Berlin on Monday.

     The silver colored monoplane made only three stops en route, at Basra, Iraq; Karachi, India, and Hanoi, French Indo-China. It averaged 180 miles and hour, including stopovers. Capt. Alfred Henke said the crew encountered little difficulty. They were in constant radio contact with Japanese stations.

D-ACON was the prototype Condor, designated Fw 200 V1, Werk-Nr. 2000. It had first flown at Neulander Feld, site of the Focke-Wulf plant in Bremen, Germany, 27 July 1937. The test pilot was Kurt Waldemar Tank, an aeronautical engineer and the airplane’s designer.

Tank had proposed the airplane to Deutsche Luft Hansa as a long-range commercial transport for routes from Europe to South America. While British and American airlines were using large four-engine flying boats for transoceanic flight, their heavy weight and aerodynamic drag reduced the practical passenger and cargo loadings. A lighter-weight, streamlined land plane would be faster and could carry more passengers, increasing its desirability and practicality. Also, while the flying boats had to make an emergency water landing if one engine failed during the flight, the Focke-Wulf Condor was designed to be able to remain airborne with just two engines.

The Fw 200 V1 was an all-metal low-wing monoplane powered by four engines, with retractable landing gear. It had a flight crew of four, and was designed to carry a maximum of 26 passengers. It was 78 feet, 0 inches (27.774 meters) long with a wingspan of 108 feet, 0 inches (32.918 meters) and overall height of 20 feet, 0 inches (6.096 meters). The airliner had an empty weight of 24,030 pounds (10,900 kilograms) and gross weight of 37,479 pounds (17,000 kilograms). This increased to 39,683 pounds (18,000 kilograms) after modification to the Fw 200 S-1 configuration.

As originally built, the prototype Condor was powered by four air-cooled, supercharged 1,690.537-cubic-inch-displacement (27.703 liters) Pratt & Whitney Hornet S1E-G single-row 9-cylinder radial engines with a compression ratio of 6.5:1 and gear reduction ratio of 3:2. The S1E-G was rated at 750 horsepower at 2,250 r.p.m. to 7,000 feet (2,134 meters), and 875 horsepower at 2,300 r.p.m. for takeoff. It was 4 feet, 1.38 inches (1.254 meters) in diameter, 4 feet, 6.44 inches (1.383 meters) long, and weighed 1,064 pounds (483 kilograms).

Brandenburg‘s Pratt & Whitney engines were later replaced by Bayerische Motorenwerke AG BMW 132 L engines. BMW had been producing licensed variants of the Pratt & Whitney Hornet since 1933, and had incorporated their own developments during that time. The BMW 132 had a displacement of 27,72 liters and a gear reduction ratio of 0,62:1, and turned a two-bladed Zweiblatt-Versstellpropeller constant-speed propeller, based on Hamilton-Standard design,  with a diameter of 3,35 m

The Fw 200 V1 had a maximum speed of 233 miles per hour (375 kilometers per hour) at Sea Level. Its cruising speed was 205 miles per hour (330 kilometers per hour) at 10,000 feet (3,048 meters). The airliner’s service ceiling was 20,000 feet (6,096 meters). It could maintain level flight at 13,000 feet (3,962 meters) with 3 engines, and 10,000 feet (3,048 meters) with just two engines running. Its range at cruise speed with a 7,000 pound (3,175 kilogram) payload was 775 miles (1,247 kilometers).

For the Berlin-to-New York flight, the Fw 200’s fuel capacity was increased to 2,400 gallons (9,084 liters).

On 6 December 1938, while on approach to Manila, capital city of the Commonwealth of the Philippines, all four of D-ACON’s engines stopped. Unable to reach the airfield, the Condor was ditched in Manila Bay. All aboard were quickly rescued. The cause of the engines failing was fuel starvation. One source states that the crew had selected the wrong tanks. Another source says that a fuel line had broken. A third cites a fuel pump failure.

The wreck of the first Condor was recovered, however, the airplane was damaged beyond repair.
