I would like to express my gratitude to Luis Féliz-Tirado without whom many additions in this present edition were not possible. His tutorials, his carefully testing, his positive criticism and even is help in putting together many files of this program, are most appreciated. SBuilderX also benefited from the support of many FSX experts. Here is an incomplete list: João Hespanha, Richard Ludowise, José Lobo, Holger Sandmann, Scott Gridley, Luis Feliz Tirado, Scott Smart, Dick Boley, Ian Gallacher, Ross Casey, Lance Tucker, Mischa, and Arno Gerretsen. I am also grateful to Manfred Moldenhauer for Scasm, Pete Dowson for FSUIPC, Paul Henty for FsuipcClient, Jon Masterson for jmBglLib, and to the authors of the “Shapelib” software. Finally, I would like to thank the Microsoft FSX Aces Team for making FSX.
