The well known Rafale by Gator was released back in December 2002 and while it has been successfully ported into FS2004 there has never been a publically available Rafale built specifically for FS2004. That will change very shortly with the release of a new Rafale C from Vincent Hellegouarch, Philippe Devallez, and Alexandre Baffert (Rafale VPA). The aircraft will feature four external configurations, four texture sets, and a complete and very clickable virtual cockpit and 2D instrument panel. Please visit this preview page for more information and images.
