[2] The SBJ project was unveiled at the 2004 NBAA convention, backed by US billionaire Robert Bass, with introduction targeted at 2011 for a $1.2–1.4 billion development cost, anticipating a 250–300 aircraft civil market over 10 years.

[6] In March 2012, UK-based Indigo Lyon joined Swiss ExecuJet Aviation Group as sales agents outside North America.

It would have a conventional aluminium fuselage and a composite supersonic natural laminar flow wing, with existing Pratt & Whitney JT8D-219 engine for a 40,800 kg (90,000 lb) gross-weight.

[12] The experiments were intended to influence future laminar flow airfoil manufacturing standards for surface quality and assembly tolerances.

[17] The new test surface was designed to provide large extents of laminar flow and be shaped so boundary layer instabilities grow relatively slowly and smoothly.
