A long-bodied, slant-winged model that attracts considerable public attention has moveable wings to reduce noise and drag, enabling it to travel at Mach 12 speeds while transporting 2,000 passengers, five times as many as the 747. This plane is still under study, but it may well be the prototype for passenger planes of the future.
很多人以為這架飛機模型的機翼做歪了；其實，這是一架可隨風向氣流而調整的可變翼飛機，可減少噪音與阻力，速度可達音速的十二倍，目前仍在研究中，是未來民航機的理想機型。它的容量甚大，預計可容納二千人，是巨無羈的五倍。
