In February 1916, the landscape of German aviation underwent a significant transformation when the south German engineering company MAN AG and several banks acquired the struggling Otto-Flugzeugwerke, establishing Bayerische Flugzeugwerke AG (B.F.W.). Pressed by the urgency of wartime demands, B.F.W. initially produced aircraft under license from Albatros Flugzeugwerke. By the end of 1916. B.F.W. rapidly scaled up production, reaching a remarkable output of over 200 aircraft per month and employing a workforce of 3,000, solidifying its position as one of Bavaria’s largest aircraft manufacturers.
Post-WWI challenges hit B.F.W. hard, necessitating a shift in focus due to the collapse of military demand for aircraft. The company, armed with cutting-edge joinery equipment used in aircraft construction, transitioned to manufacturing furniture and fitted kitchens. The remnants of its aviation legacy, including materials sufficient for approximately 200 aircraft, valued at 4.7 million reichsmarks, fueled this strategic pivot. Additionally, from 1921 onwards, B.F.W. ventured into the production of motorcycles under the brand names Flink and Helios.In 1921, Austrian financier Camillo Castiglioni expressed interest in acquiring B.F.W. Despite initial resistance Castiglioni, with the support of BMW’s Managing Director Franz Josef Popp, secured the acquisition. This paved the way for a merger between B.F.W. and BMW in May 1922, aligning the aircraft manufacturing expertise of B.F.W. with BMW’s engine capabilities. Willy Messerschmitt, appointed chief designer and engineer in 1927, played a pivotal role in shaping the company’s future.

The journey took an unexpected turn with the design of the Messerschmitt M20, which proved challenging and resulted in several prototypes crashing. Erhard Milch, head of Deutsche Luft Hansa, terminated contracts with Messerschmitt, leading to B.F.W.’s bankruptcy in 1931. However, Messerschmitt’s connection with Hugo Junkers facilitated a revival in 1933, overcoming opposition from Milch. The subsequent focus on “lightweight construction” and groundbreaking designs like the Bf 109 marked a turning point. As Messerschmitt became favored by the Nazi party, B.F.W. rebranded as “Messerschmitt AG” in 1938. The RLM designation prefix shifted from “Bf” to “Me,” reflecting the new era of aviation under Messerschmitt’s leadership.

The First Jet
In the turbulent years preceding World War II, a significant development took place in the aviation industry that would shape the course of aerial warfare. The concept of “lightweight construction” introduced by Messerschmitt proved instrumental in the development of innovative aircraft designs.
The narrative further unfolds with the introduction of jet engine technology. The successful test flights of the Heinkel He 178, the world’s first jet aircraft, spurred the Germans to adopt jet engines for advanced fighter aircraft. The Me 262, already under development before the war, faced challenges with technical issues related to the new jet engine. The design underwent significant modifications, including the shift from wing-root-mounted engines to underwing pods, allowing more flexibility in maintenance.

The Me 262, with its swept wings and jet propulsion, became a groundbreaking achievement. The prevailing lack of funding for the jet engine program, influenced by officials’ skepticism about the efficacy of unconventional aircraft, posed hurdles. Hermann Göring, head of the Luftwaffe, cut funding, and Willy Messerschmitt faced challenges in maintaining mass production of piston-powered aircraft like the Bf 109.
Bf 109The Me 262’s journey, from the initial setbacks to its successful flight with Jumo 004 engines in July 1942, stands as a testament to Messerschmitt’s resilience and the innovation that defined the aviation landscape during those years.
Ludwig Bölkow, a prominent aerodynamicist, played a pivotal role in the intricate design process of the Me 262, contributing to its aerodynamic excellence. His initial focus was on the wing design, where he employed NACA airfoils modified with an elliptical nose section, showcasing meticulous attention to detail.
As the design process progressed, Bölkow introduced modifications to enhance performance. This thoughtful selection aimed at optimizing the wing’s aerodynamic efficiency and overall effectiveness. The distinctive elliptical nose derivatives of the NACA airfoils extended to the horizontal and vertical tail surfaces, ensuring a cohesive and harmonized design throughout the aircraft’s structure. Bölkow’s choices reflected a commitment to precision, acknowledging the critical role these surfaces played in the Me 262’s maneuverability and stability.The wings themselves were a testament to engineering ingenuity, featuring a single-spar cantilever construction with stressed skins. The thickness of the skin varied strategically, ranging from 3 mm at the root to 1 mm at the tip. This meticulous design not only contributed to the aircraft’s structural integrity but also optimized its weight distribution for superior flight performance. In a pragmatic move to expedite construction, reduce weight, and conserve strategic materials during the challenging final stages of the war, the wing interiors were left unpainted. The attachment of the wings to the fuselage was a critical aspect of the design, and Bölkow implemented a robust connection mechanism. Four points of attachment were secured using a pair of 20 mm and forty-two 8 mm bolts, ensuring structural stability and durability.

Operability
The Me 262, represents a groundbreaking aircraft in the annals of aviation history. As the war progressed, Adolf Hitler’s strategic vision for the Me 262 evolved, envisioning it as a high-speed, light-payload Schnellbomber or “fast bomber.” This shift in focus towards ground-attack and bomber roles, known as the Sturmvogel variant, posed challenges and contributed to delays in bringing the Schwalbe (Swallow) into operational status. Engine vibration issues further complicated the timeline, and Albert Speer, Minister of Armaments and War Production, highlighted Hitler’s initial resistance to mass production of the Me 262 in favor of using it as a bomber for revenge attacks.
The formation of Erprobungskommando 262 in April 1944 marked a crucial phase in the introduction of the Me 262 into service. Trials progressed slowly, and it was not until August 1944 that initial operational missions were flown against the Allies. Major Walter Nowotny’s leadership, albeit short-lived due to his death, paved the way for the unit’s transformation into Kommando Nowotny, a trials and development unit conducting the world’s first jet fighter operations.
Erprobungskommando 262
Notably, on 26 November 1944, a Me 262 became the first confirmed ground-to-air kill of a jet combat aircraft. The aircraft faced challenges on multiple fronts, including encounters with Bofors guns and other ground fire. By January 1945, Jagdgeschwader 7 (JG 7), a pure jet fighter wing, became operational, and large-scale attacks on Allied bomber formations ensued in March 1945. The Me 262’s incredible speed, exceeding that of any Allied fighter, presented a paradigm shift in aerial combat. Despite its deficiencies, the Me 262 emerged as a formidable force, showcasing the beginning of the end for piston-engined aircraft as effective fighting machines.
The Me 262’s top aces, including Hauptmann Franz Schall and Oberleutnant Kurt Welter, achieved notable success against Allied aircraft. The innovative tactics employed by Me 262 pilots, such as the roller-coaster attack, showcased the need for new strategies to maximize the effectiveness of the aircraft’s firepower. As World War II neared its conclusion, Me 262s were committed to ground assault missions, attempting to support German troops in the face of advancing Red Army forces. The aircraft’s operational life extended until the last days of the conflict, with notable actions, including the last Luftwaffe air victory scored by Oblt. Fritz Stehle on 8 May 1945.The Me 262, left an indelible mark on aviation history, paving the way for the future of jet-powered aircraft. Its unmatched speed and innovative design signaled a paradigm shift, foreshadowing the end of an era dominated by traditional piston-engined fighters.A prominent Royal Navy test pilot, Captain Eric Brown, chief naval test pilot and commanding officer of the Captured Enemy Aircraft Flight Royal Aircraft Establishment, who tested the Me 262 noted that:
This was a Blitzkrieg aircraft. You whack in at your bomber. It was never meant to be a dogfighter, it was meant to be a destroyer of bombers… The great problem with it was it did not have dive brakes. For example, if you want to fight and destroy a B-17, you come in on a dive. The 30mm cannon were not so accurate beyond 600 metres. So you normally came in at 550 m and would open fire on your B-17. And your closing speed was still high and since you had to break away at 200 metres to avoid a collision, you only had two seconds firing time. Now, in two seconds, you can’t sight. You can fire randomly and hope for the best. If you want to sight and fire, you need to double that time to four seconds. And with dive brakes, you could have done that.
The Me 262 underwent a series of flight tests, revealing certain limitations and challenges. Dive tests indicated that the aircraft would go out of control in a dive at Mach 0.86. Further increases in Mach numbers would result in a nose-down trim that the pilot could not counter. This condition would lead to a steepening of the dive, causing higher speeds and ultimately resulting in the airframe disintegrating due to excessive negative g-loads.Messerschmitt envisioned that the HG series of Me 262 derivatives could achieve transonic Mach numbers in level flight. The top speed of the HG III was projected to be Mach 0.96 at an altitude of 6,000 meters (20,000 feet). After World War II, the Royal Aircraft Establishment (RAE), a leading institution in high-speed research, conducted tests on the Me 262 to aid British attempts at surpassing Mach 1. The RAE achieved speeds of up to Mach 0.84 and confirmed the results obtained from Messerschmitt’s dive tests. Similar tests were conducted by the Soviets.A claim was made by former Me 262 pilot Hans Guido Mutke after Willy Messerschmitt’s death in 1978. Mutke asserted that he had exceeded Mach 1 on April 9, 1945, in a Me 262 during a “straight-down” 90° dive. However, this claim relies solely on Mutke’s memory and lacks altitude readings to determine the speed accurately. The structural design of the Me 262, with its slight wing sweep primarily for trim reasons, would likely have led to structural failure due to divergence at high transonic speeds.

Post-War
After World War II, Willy Messerschmitt faced a denazification court trial for using slave labor, and in 1948, he was convicted of collaborating with the Nazi regime. Following two years in prison, he was released and resumed his position as the head of his company. Due to Germany’s prohibition on manufacturing aircraft until 1955, Messerschmitt shifted his company’s focus to manufacturing prefabricated buildings, sewing machines, and small cars, notably the Messerschmitt Kabinenroller.
Messerschmitt Kabinenroller.He exported his talents to Francoist Spain, where he designed the Hispano HA-200 jet trainer for Hispano Aviación in 1952. Eventually, he was allowed to return to aircraft manufacturing in Germany, where he licensed-produced the Fiat G91 and later the Lockheed F-104 Starfighter for the West German Luftwaffe. His final aircraft design was the Helwan HA-300, a light supersonic interceptor for the Egyptian air forces.

Helwan HA-300Messerschmitt guided his company through mergers, first with Bölkow in 1968 and then with Hamburger Flugzeugbau in 1969, leading to the formation of MBB (Messerschmitt-Bölkow-Blohm). MBB later became part of EADS, now named Airbus, with Messerschmitt serving as chairman until 1970 when he retired. He passed away on September 15, 1978, in a Munich hospital under undisclosed circumstances.Messerschmitt’s design philosophy focused on performance, emphasizing lightweight construction and minimizing parasitic drag. However, critics argued that he sometimes took this approach to the extreme. For instance, his disagreement with Harth was over designs that Harth considered dangerously unstable. The Me 210, designed by Messerschmitt, also exhibited instability, requiring an enlargement of the airframe and aerodynamic surfaces to address the issue, which increased drag and weight.After World War II, the Me 262 and other advanced German technologies, including jet engines, were swiftly taken by the Soviets, British, and Americans as part of the USAAF’s Operation Lusty. Many Me 262s found in repairable condition were confiscated for evaluation. Testing revealed that the Me 262 was faster than the British Gloster Meteor, providing better visibility to the sides and rear, and serving as a superior gun platform compared to the Meteor F.1. However, it had a shorter range and less reliable engines. British test pilot Captain Eric Brown, who flew a captured Me 262, considered it “the most formidable aircraft of WW2.” He highlighted its innovative features, including swept-back wings, axial flow jet engine, and four powerful 30mm cannons. In terms of performance, he noted that it outclassed other planes of the time and provided unmatched speed, allowing pilots to dictate the terms of combat.The USAAF compared the Me 262 with the Lockheed P-80 Shooting Star, concluding that the Me 262 was superior in acceleration and speed, with similar climb performance and a higher critical Mach number. The Americans also tested an unarmed photo reconnaissance version, the Me 262A-1a/U3, which completed eight flights between May and August 1946. The aircraft’s extensive study aided the development of early American, British, and Soviet jet fighters. The slat design of the F-86, designed by engineer Edgar Schmued, was influenced by the Me 262.
