A very special thanks is due to the following people and groups. Note: as hard as we've tried, it is impossible to perfectly maintain this file. If you are aware of someone who you think should be included here, PLEASE let me know. Projects like this are made possible only by the help and hard work of others. I want to properly credit everyone who has contributed to this project. A1 Free Sounds http://www.a1freesoundeffects.com Granted permission for the flightgear project to use some of the sound effects from their site. Syd Adams: Added clipping to 2d instruments. Added volume control to ATC-chatter. Created and maintain: DHC2, B1900D, Aerostar 700, S76C+ helicopter, Cessna Citation Bravo & CitationX, A6M2 'Zero'. Assisted with Cessna Citation II with Curt and 777-200 with Justin Smithies. Gilberto Agostinho Contributed work to the default scenery (new textures and better materials definitions, mostly committed by Thorsten into FGDATA. Contributed to the highly detailed c172p (textures, sounds and programming). Mark Akermann Redone sun code. The sun now consists of three textures with individual colors which are calculated based on the effect of light scattering. This is accomplished by using various environmental data and by calculating the distance the light travels through the atmosphere. Raul Alonzo Mr. Alonzo is the author of Ssystem and provided his kind permission for using the moon texture. I also used parts of his code as a template when adding the texture. Ssystem Homepage can be found at: http://www1.las.es/~amil/ssystem Michele America Contributed to the HUD code. Emmanuel Baranger <> Many, many very nice aircraft models. Andrei Barbu "T"Eval" teval@myrealbox.com Designed and implemented the current version of the FlightGear website. Michael Basler Author of the Getting Started guide. Paul Beardsley The 1903 Wright Flyer was inspired by a model contributed by Paul Beardsley. Very little of the original model remains, but without Paul's excellent work we might not have our own 1903 Flyer. Model was reworked and retextured by Jim Wilson. Jon S. Berndt Chief architect of JSBSim, the default flight dynamics model (FDM) for FlightGear. Jon's professional work has involved simulation and prototyping for vehicles ranging from the F-16 to his current work on the space shuttle and future manned launch vehicles. Since 1998 Jon has been working on creating JSBSim together with co-author Tony Peden. JSBSim is an object-oriented, multi-platform aerospace vehicle simulator that can be integrated with broader flight simulation programs (since it provides no visual model), or run in a standalone mode for batch runs. For more information, see the JSBSim home page at: http://www.jsbsim.org Paul Bleisch Paul redid the "debug" system so that it would be much more flexible, so it could be easily disabled for production system, and so that messages for certain subsystems could be selectively enabled.

Scripts for automated source downloads and builds. Bernhard H. Buckel Contributed the README.Linux Co-Author of the "Getting Started Manual" Gene Buckle Gene has done a lot of work getting FG to compile with the MSVC++ compiler. Also, he has pushed, proded, and bugged me endlessly to do my stuff right.
