Rank and Organization: Colonel, U.S Army Air Corps, 44th Bombardment Group (Heavy), 9th Air Force. Action: Ploetsi Raid, Rumania, 1 Aug 1943. Entered Service at: Moline, Kans. Born: Columbia, Mo. G.O. No.: 54, September 7, 1943.
Citation: For conspicuous gallantry in action and intrepidity at the risk of his life above and beyond the call of duty on August 1, 1943. Col. Johnson, as commanding officer of a heavy bombardment group, let the formation of the aircraft of his organization constituting the fourth element of the mass low-level bombing attack of the 9th U.S. Air Force against the vitally important enemy target of the Ploesti oil refineries. While proceeding to the target on this 2,400-mile flight, his element became separated from the leading elements of the mass formation in maintaining the formation of the unit while avoiding dangerous cumulous cloud conditions encountered over mountainous territory. Though temporarily lost, he reestablished contact with the third element and continued on the mission with this reduced force to the prearranged point of attack, where it was discovered that the target assigned to Col. Johnson’s group had been attacked and damaged by a preceding element. Though having lost the element of surprise upon which the safety and success of such a daring form of mission in heavy bombardment aircraft so strongly depended, Col. Johnson elected to carry out his planned low-level attack despite the thoroughly alerted defenses, the destructive antiaircraft fire, enemy fighter airplanes, the imminent danger of exploding delayed action bombs from the previous element, of oil fires and explosions, and of intense smoke obscuring the target. By his gallant courage, brilliant leadership, and superior flying skill, Col. Johnson so led his formation as to destroy totally the important refining plants and installations which were the object of his mission. Col. Johnson’s personal contribution to the success of this historic raid, and the conspicuous gallantry in action, and intrepidity at the risk of his life above and beyond the call of duty demonstrated by him on this occasion constitute such deeds of valor and distinguished service as have during our Nation’s history formed the finest traditions of our Armed Forces.

Citation: For conspicuous gallantry in action and intrepidity at the risk of his life above and beyond the call of duty on 1 Aug 1943. On this date he led the third element of heavy bombardment aircraft in a mass low-level bombing attack against the vitally important enemy target of the Ploesti oil refineries. En route to the target, which necessitated a round-trip flight of over 2,400 miles, Col. Kane’s element became separated from the leading portion of the massed formation in avoiding dense and dangerous cumulous cloud conditions over mountainous terrain. Rather than turn back from such a vital mission he elected to proceed to his target. Upon arrival at the target area it was discovered that another group had apparently missed its target and had previously attacked and damaged the target assigned to Col. Kane’s element. Despite the thoroughly warned defenses, the intensive antiaircraft fire, enemy fighter airplanes, extreme hazards on a low-level attack of exploding delayed action bombs from the previous element, of oil fires and explosions and dense smoke over the target area, Col. Kane elected to lead his formation into the attack. By his gallant courage, brilliant leadership, and superior flying skill, he and the formation under his command successfully attacked this vast refinery so essential to our enemies’ war effort. Through his conspicuous gallantry in this most hazardous action against the enemy, and by his intrepidity at the risk of his life above and beyond the call of duty, Col. Kane personally contributed vitally to the success of this daring mission and thereby rendered most distinguished service in the furtherance of the defeat of our enemies.
1 August 1943: Operation TIDALWAVE. 178 B-24 Liberator very long range heavy bombers bombers of the 8th and 9th Air Forces, with 1,751 crewmen, made an extreme low-level attack on the Axis oil refineries at Ploesti, Romania.
The mission was a disaster: 53 B-24s were lost, 310 crewmen killed in action, 108 captured, and 78 interred in neutral countries. The damaged refineries were repaired within weeks and their output was higher than before the attack.
Five Medals of Honor were awarded, three posthumously, the most for any single air action in history.
The following is from an official U.S. Air Force publication:
U.S. Air Force Fact Sheet
OPERATION TIDALWAVE, THE LOW-LEVEL BOMBING OF THE PLOESTI OIL REFINERIES, 1 AUGUST 1943
Prior to World War II, the U.S. Army Air Corps (Army Air Forces as of June 20, 1941) developed a doctrine of high-altitude, precision, daylight, massed bombing of selected enemy military and industrial targets. Combined with the Royal Air Force’s concentration on mass air attacks on industrial areas at night by 1943, this doctrine evolved into the Combined Bomber Offense featuring “around-the-clock” bombing of German targets.
Petroleum production and distribution systems were among the highest priority targets, and perhaps the most inviting of these was the concentration of oil refineries at Ploesti, Rumania, which according to Allied intelligence estimates, produced as much as one third of Germany’s liquid fuel requirements. One of the most heavily defended targets in Europe, Ploesti lay outside the range of Allied bombers from England but could be reached by Consolidated B-24 Liberator bombers from the Middle East or North Africa.
Allied leaders determined to bomb Ploesti during the Casablanca Conference in January 1943 and Gen. Henry H.” Hap’ Arnold delegated the problem to Col. Jacob Smart of his Advisory Council. Smart, the principle architect and planner for Operation TIDALWAVE, proposed, in complete antithesis of USAAF bombing policy, a low-level massed raid on the nine most important Ploesti refineries by five B-24 bomb groups, two from North Africa and three borrowed from Eighth Air Force in England .
By July 1943, the five groups—the 44th, 93rd, and 389th Bombardment Groups from England had joined the 98th and 376th Bombardment Groups at Benghazi, Libya, where they made final preparations and conducted additional low-level training under the direction of Ninth Air Force.
Commanded by Brig. Gen. Uzal G. Ent, the force of 178 B-24s took off on the morning of 1 August, followed a route across the Mediterranean, passed the island of Corfu, crossed the Pindus Mountains into Rumania, and approached Ploesti from the east. While over the Mediterranean the formation divided into two parts: the first led by Col. Keith K. (K.K.) Compton commander of the 376th, consisted of the 376th and 93rd Bomb Groups; the second led by Col. John R. (Killer) Kane, commander of the 98th, included the 98th, 44th, and 389th Bomb Groups. Mandated radio silence prevented the leaders from reassembling the formation. The goal of a single, mass attack disappeared.
Compton’s formation reached Rumania well ahead of Kane’s. It descended to low level and, in error, made its planned turn to the south at Targoviste, miles short of the correct Identification Point (IP). Compton led two bomb groups toward Bucharest. Col. Addison L. Baker, commanding the 93rd Bomb Group following Compton, saw Ploesti to his left, turned his group and led it into the target first. Meantime, Compton found that he was heading to Bucharest and turned, almost reversing course, and bombed Ploesti from the south.
As the two groups emerged from Ploesti and escaped to the south, the 98th and 44th Bomb Groups led by Kane plunged into Ploesti where they found many of their targets in flames. They sought alternate targets of opportunity. Far to the north, the 389th Bomb Group successfully bombed its target, a separate refinery at Campina, as planned.
Survivors of the attack fled south alone or in small groups trailed by Axis fighters which took a toll of the weakened force. Bombers crashed in fields or disappeared into the water; some diverted to Allied bases in the region; others sought sanctuary in neutral Turkey. Some 88 B-24s, most badly damaged, managed to return to Benghazi. Personnel losses included 310 airmen killed, 108 captured, and 78 interned in Turkey. Five officers: Kane, Baker, Col. Leon W. Johnson, Maj. John L. Jerstad, and 2nd Lt. Lloyd H. Hughes, earned the Medal of Honor; Baker, Jerstad, and Hughes posthumously.
Despite the extreme heroism of the airmen and their determination to press the mission home, the results of Operation TIDAL WAVE were less than expected. TIDALWAVE targeted nine major refineries that produced some 8,595,000 tons of oil annually, about 90 percent of all Rumanian oil production, and the attack temporarily eliminated about 3,925,000 tons, roughly 46 percent of total annual production at Ploesti. Three refineries lost 100 percent of production. Unfortunately, these losses figures were temporary and reflected much less than the planners had hoped for. The Germans proved capable of repairing damage and restoring production quickly, and they had been operating the refineries at less than full capacity, anyway. Ploesti thus had the ability to recover rapidly. The largest and most important target, Astro Romana, was back to full production within a few months while Concordia Vega was operating at 100 percent by mid-September.
The U.S. Army Air Forces never again attempted a low level mission against German air defenses.

1 August 1939: Captains Clarence S. Irvine and Pearl H. Robey, United States Army Air Corps, used the Boeing Y1B-17A Flying Fortress (Model 299F), serial number 37-369, to set a Fédération Aéronautique Internationale (FAI) World Record for Altitude with a 5,000 Kilogram Payload. The bomber climbed to 10,371 meters (34,026 feet) with a payload of 11,023 pounds.¹ ²
On the same day, Irvine and Robey flew the Y1B-17 from Dayton, Ohio to St. Jacob, Illinois, setting an FAI World Record for Speed Over 1,000 Kilometers with a 5,000 Kilogram Payload, averaging 417.46 kilometers per hour (259.40 miles per hour).³
The single Y1B-17A (Boeing Model 299F) was originally ordered as a static test article, but when that was determined to be unnecessary, it was used as an engine test aircraft. It was equipped with four 1,823.129-cubic-inch-displacement (29.875 liter) air-cooled, supercharged, Wright R-1820-51 (Cyclone G59) single-row nine-cylinder radial engines. Moss/General Electric turbo-superchargers were installed, initially on top of the wings, but were moved to the bottom of the engine nacelles.
The supercharged Wright R-1820-39 (Cyclone R-1820-G5) engines of the YB-17s were rated at 805 horsepower at 2,100 r.p.m., at Sea Level, 775 horsepower at 14,000 feet (4,267 meters), and 930 horsepower at 2,200 r.p.m., for take off. By contrast, the YB-17A’s R-1820-51 engines were rated at 800 horsepower at 2,100 r.p.m. at Sea Level, and 1,000 horsepower at 2,200 r.p.m. for take off. But the turbochargers allowed the engines to maintain their Sea Level power rating all the way to 25,000 feet (7,620 meters). Both the -39 and -51 engine had a 16:11 propeller gear reduction ratio. The R-1820-51 was 3 feet, 9.06 inches (1.145 meters) long, 4 feet, 6.12 inches (1.375 meters) in diameter, and weighed 1,200.50 pounds (544.54 kilograms). 259 were produced by Wright between September 1937 and February 1940.
The turbo-superchargers installed on the YB-17A greatly improved the performance of the bomber, giving it a 55 mile per hour (89 kilometer per hour) increase in speed over the supercharged YB-17s, and increasing the bomber’s service ceiling by 7,000 feet (2,132 meters). The turbo-superchargers worked so well that they were standard on all following B-17 production models.
The Boeing Y1B-17A was 68 feet, 9 inches (20.955 meters) long with a wingspan of 103 feet, 9–3/8 inches (31.633 meters) and height of 14 feet, 11–5/16 inches (4.363 meters). Its empty weight was 26,520 pounds (12,029 kilograms). The maximum gross weight was 45,650 pounds (20,707 kilograms)
The Model 299F had a cruise speed of 230 miles per hour (370 kilometers per hour), a maximum speed of 271 miles per hour (436 kilometers per hour) at Sea Level and 295 miles per hour (475 kilometers per hour) at 25,000 feet (7,620 meters). The service ceiling was 38,000 feet (11,582 meters). The maximum range was 3,600 miles (5,794 kilometers). Carrying a 4,000 pound (1,814 kilogram) load of bombs, the range was 2,400 miles (3,862 kilometers).
The Y1B-17A could carry eight 600 pound (272 kilogram) bombs in an internal bomb bay. Defensive armament consisted of five .30-caliber machine guns.
Following the engine tests, 37-369 was re-designated B-17A.

² This record-setting flight was dramatized in the motion picture “Test Pilot,” (1938, Metro-Goldwyn-Mayer) with Clark Gable, Spencer Tracy and Myrna Loy. This movie is now 80 years old and has a melodramatic plot, but is well worth seeing for aviation history enthusiasts.
1 August 1911: After 33 flight lessons over a four-month period at the Moisant Aviation School at Hempstead, Long Island, New York, Harriet Quimby took her flight test and became the first woman to receive a pilot’s license, Number 37, from the Aero Club of America. She was “America’s First Lady of the Air.”
She was well-known throughout the United States and Europe, and wore a purple satin flying suit.
On 16 April 1912 she became only the second pilot to fly across the English Channel when she flew from Dover to Calais in 59 minutes with a Blériot monoplane.
Eleven months after receiving her pilot’s license, 1 July 1912, Harriet Quimby was killed when she fell from her Blériot XI during a flying demonstration at Squantum, Massachusetts.
