Information:
The SyberJet SJ30 series represents a line of high-performance light business jets designed to achieve midsize-jet speeds and transcontinental range. The SJ30-1 served as the initial proof-of-concept prototype, featuring a shorter fuselage and smaller wing design. The SJ30-2 became the definitive production model, which was "stretched" by four feet to increase cabin space and improve aerodynamics.
