Triangular Passenger Plane by NASA

A new triangular 'passenger plane' which is reminiscent of spy planes is ready and has already undergone test flights.
The super plane so far codenamed as 'X-48 C' is the brainchild of the US space agency NASA which is developing it in collaboration with aviation major Boeing.
It will become a dominant design within the next 10 to 15 years.It is having more fuel capacity as compared to other flights.
The Passenger-less small spy planes are usually named as X-48 series. The X-48C retains most dimensions of the earlier models, with a wingspan just longer than 20 feet, and a weight of about 500 pounds.
The aircraft will disappoint the travelers who insist on window seats.It will not have more window seats due to its triangular shape.
