The concept of a winged flight harness for Sam Wilson, the Falcon, predates the MCU's EXO-7 by several decades. The Falcon first appeared in Captain America #117 (September 1969), created by writer Stan Lee and artist Gene Colan. Initially, Wilson had no flight capability and was primarily an expert bird trainer, most notably of his falcon, Redwing. The iconic wings were introduced later in Captain America #170 (February 1974). This groundbreaking upgrade was conceived in-universe by T'Challa, the black_panther, and was constructed in wakanda. This original comic book harness was described as being made of a lightweight titanium rib structure and Mylar. Over the years, this harness was consistently upgraded, eventually becoming a sophisticated piece of Wakandan technology composed of Vibranium and featuring advanced psionic controls. For the Marvel Cinematic Universe, the filmmakers sought a more grounded, military-realism approach for Sam Wilson's introduction in Captain America: The Winter Soldier (2014). The production team, including concept artists like Josh Nizzi, developed the EXO-7 Falcon as a believable piece of experimental military hardware. The name “EXO-7” itself adds to this verisimilitude, suggesting a project designation within a military R&D program. This creative choice firmly rooted Sam Wilson's abilities not in foreign advanced technology, but in his own direct military experience, which became a cornerstone of his character in the MCU. The visual design has evolved significantly through the films, reflecting both technological advancements within the universe (like Stark and Wakandan tech) and Sam's growing importance as a hero.
The origin of Sam Wilson's flight capabilities differs dramatically between the comics and the cinematic universe, representing one of the most significant adaptations for the character.
In the prime Marvel comic continuity (earth_616), Sam Wilson's wings have no connection to the U.S. military. After a period of adventuring with Steve Rogers, Sam's potential was recognized by King T'Challa of Wakanda. T'Challa, utilizing Wakanda's unparalleled technological resources, designed and gifted Sam a custom flight harness. This initial harness was a marvel of engineering, but it was the subsequent upgrades that defined its power. The Wakandan Design Group eventually replaced the original with a new version made of pure vibranium. A key feature of this advanced harness is its psionic link. The wings are mentally controlled by Sam Wilson, allowing for an incredible degree of maneuverability and responsiveness that would be impossible with manual controls. The wings can reconfigure into various flight patterns, from gliding to high-speed propulsion. Furthermore, the comic harness incorporates “hard-light” technology. Sam can manifest the wings as razor-sharp, multi-faceted “feathers” that can be used as projectiles or defensive shields. The entire suit is interwoven with a vibranium-microweave mesh, granting him significant ballistic and impact resistance. The visor of his suit contains a wide array of sensors, including infrared, magnetic resonance imaging, and telescopic vision, making him a formidable aerial reconnaissance expert. This origin ties Sam's power directly to the generosity and technological prowess of Wakanda, forging a strong early link between the Falcon and the Black Panther.
Within the MCU, the EXO-7 Falcon was an experimental prototype developed for the united_states_air_force's Para-rescue division. The project was designed to provide soldiers with rapid, individual aerial insertion and extraction capabilities in hostile environments where traditional aircraft would be too vulnerable. The suit consists of a backpack-style jetpack and a pair of articulated, high-tensile carbon fiber wings for steering, gliding, and defense. Sam Wilson was one of the two primary test pilots for the program, along with his wingman, Riley. During a mission, Riley's EXO-7 was struck by an RPG, and despite Sam's efforts, Riley was killed. This traumatic event led to Sam's decision to leave the Air Force and the subsequent mothballing of the EXO-7 project. Sam retained one of the prototype harnesses after his discharge. He first deployed it again when Steve Rogers and Natasha Romanoff sought his help in their fight against HYDRA and the winter_soldier. Sam “borrowed” the suit from its storage facility at Fort Meade. This origin establishes the EXO-7 not as a gift from a technologically advanced nation, but as a piece of Sam's own past and a tool of his military service. It grounds his character in a real-world military context and makes his decision to become a hero a personal choice to reclaim a part of himself he had left behind.
The functional design and technological basis of the flight systems used by Sam Wilson are fundamentally different across the two primary continuities.
The Wakandan flight harness is a pinnacle of Afro-futuristic technology, blending advanced materials with a unique control interface.
The MCU's EXO-7 is a piece of modular military hardware that has seen several distinct iterations and upgrades, reflecting the evolving technological landscape of the universe.

While designed for a specific military purpose, the history of the EXO-7 Falcon is almost exclusively the history of its primary operator, Sam Wilson.
Sam Wilson is the definitive and, for most of its operational life, the sole user of the EXO-7 technology. His journey with the harness mirrors his journey as a hero. Initially, he uses it as a reluctant soldier returning to the fight, relying on his training to support Steve Rogers. As he becomes the Falcon, an Avenger, he masters the suit, turning it into an extension of his body. He develops a unique aerial combat style that blends high-speed fly-bys with close-quarters combat. The suit allows him to be the “eyes in the sky” for the ground-based Avengers. His ultimate acceptance of the Captain America mantle is intrinsically linked to the final, Wakandan-upgraded version of the suit, symbolizing the fusion of his own identity (the wings) with the legacy he is adopting (the shield and uniform).
The EXO-7 project was a short-lived R&D initiative by the U.S. Air Force. Its goal was to create a new class of soldier capable of operating in three-dimensional space with unprecedented mobility. The program was shut down after the death of Sam's wingman, Riley, during a field test, highlighting the extreme danger and skill required to operate the harness effectively. Its existence was likely classified, and it was never deployed on a wide scale.
Throughout its operational history, the EXO-7 has been a critical tool in combating a wide range of threats:
The EXO-7 Falcon has been at the center of several pivotal moments within the Marvel Cinematic Universe.
This was the EXO-7's baptism by fire. Pulled out of storage, the suit was Sam Wilson's entry into the world of superheroes. He skillfully used its flight capabilities to evade HYDRA forces and provide aerial support for Captain America and Maria Hill. Its most critical role was in the final battle, where Sam flew through a maelstrom of anti-aircraft fire to help Captain America swap out the Helicarriers' targeting blades, a feat that would have been impossible without the harness. This event established the EXO-7 as a key tactical asset.
During the ideological battle over the sokovia_accords, the EXO-7 was a frontline tool for Team Captain America. The airport battle at Leipzig/Halle showcased the suit's full capabilities. Sam used the Redwing drone for reconnaissance to track Spider-Man, engaged in a high-speed dogfight with War Machine, and used the wings as both weapons and shields in close combat. The fight also revealed its vulnerabilities, as it was damaged by Vision's energy beam and ultimately disabled by War Machine's sonic cannon.
After being restored to life following the Blip, Sam Wilson, wearing his Stark-upgraded EXO-7, was one of the first heroes to arrive through the portals at the destroyed Avengers compound. His iconic line, “On your left,” signaled the return of the heroes and the turning of the tide against Thanos. He played a crucial air support role throughout the massive battle, protecting the Infinity Gauntlet and engaging Thanos's forces from the air, demonstrating the importance of aerial superiority in the conflict.
This storyline represents the apotheosis of the EXO-7 technology. After giving up the shield, Sam's journey to reclaim it and accept his role as the new Captain America culminates in the creation of the final Wakandan suit. The suit's public debut during the fight against the Flag Smashers in New York is a defining moment. It is no longer just the “Falcon” suit; it is the flight-capable uniform of Captain America. The seamless integration of the wings and the red, white, and blue motif symbolized the merging of Sam's identity with Steve's legacy, creating a hero who was wholly new yet deeply traditional.
While the EXO-7 is an MCU-specific design, the concept of a winged harness for Falcon exists in other Marvel media.
