At first glance, it bears a strong resemblance to the Cirrus SF50 Vision Jet. A sleek, low-wing, V-tail jet with a single engine mounted in a dorsal pod, the two aircraft share the same layout and look nearly identical. But in fact, the aircraft pictured is the sole Eclipse 400, and flew a full year before the Vision Jet’s maiden flight.
Initially known as the Eclipse Concept Jet, or ECJ, the 4,700-pound jet was intended to gauge market interest for a compact, four-place “personal jet,” and would have complemented Eclipse’s primary offering—the larger, six-place Eclipse 500. With their hands full with Eclipse 500 production, the company turned to a firm called Swift Engineering to engineer and build the smaller 400.
