The first demonstration flight of the Phantom 3500 is planned for 2027.
Otto Aviation has unveiled a unique private jet, the Phantom 3500, which has no conventional windows. Instead, passengers are offered panoramic screens with a real-time view. The developers claim that this design not only increases comfort but also significantly improves aerodynamics.
Windows in aircraft are a weak point of the design: they add weight, complicate production, and worsen streamlining. The Phantom 3500 solves this problem radically—by completely abandoning them.
Window cutouts require reinforcement, create aerodynamic irregularities, and increase fuel consumption, explains Scott Drennan, president of Otto Aviation.

The removal of windows has allowed the creation of a perfectly smooth fuselage, which, according to the company, provides superlaminar flow – a key factor in reducing drag. To avoid passengers feeling like they are in a closed box, the cabin is equipped with curved screens with a 360-degree view. Cameras on the outside of the plane transmit images in real time, creating the effect of complete transparency. The developers test this technology in simulators to ensure that passengers do not experience discomfort.

Phantom 3500 Specifications
The aircraft is positioned as the most efficient business jet in its class:
-
Flight range: 5,926 kilometers;
-
Cruising altitude: 15,545 meters;
-
Speed – up to 1.2 Mach (near-sonic);
-
Emission reduction – 80% compared to analogues;
-
Short Take Off – can use runways shorter than 1,067 meters.
The first demonstration flight is planned for 2027. According to experts, if the tests are successful, the Phantom 3500 could become a new standard in business aviation.
“The aviation market is becoming more diverse. Our Phantom 3500 will fill a niche offering luxury, efficiency, and innovative design,” Drennan says.
By the way, Otto Aviation is not the only company making such solutions. Boom Supersonic is developing the supersonic Overture, and LTA Research is reviving airships.
