Power source

Gas turbines using kerosene (Jet-A1/B). It is unknown how many gas turbine engines are on this aircraft.

Carbon fiber composite

Windows

Panoramic wrap around windows allowing forward, left and right visibility for spectacular views with a solid roof above the passenger compartment

Wings

Tandem gull-wings (the rear wing is a high main gull-wing and the front gull-wing is a smaller gull-wing mounted near the middle of the fuselage)

Fixed quadricycle wheeled landing gear

Safety features

Distributed Electric Propulsion (DEP) means having multiple propellers (or electric ducted fans) and multiple electric motors on an aircraft so if one or more propellers (or electric ducted fans) or some electric motors fail, the other working propellers (or electric ducted fans) and electric motors can safely land the aircraft. DEP provides safety through redundancy for its passengers or cargo. There are also redundancies of critical components in the sub-systems of the aircraft providing safety through redundancy for its passengers or cargo. Having multiple redundant systems on any aircraft decreases having any single point of failure.
