A1 Free Sounds <techie@mail.ev1.net> 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.

Mark Akermann <flightgear@akermann.org>

  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.

  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

Paul Beardsley <Beardspa@hotmail.com>

  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

Jon S. Berndt <jon@jsbsim.org>

  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 <pbleisch@acm.org>

  system.
