Twenty-one years ago, two Flight Simulator enthusiasts had a common wish, to improve the ATC in FS. A programmer in Atlanta met an Air Traffic controller in Memphis and we created a company called JDTLLC. We began working on Radar Contact which became the best FS ATC program available for many years. In 2001, after 6 years of work, Version 4.3 was released. Seventeen years later, after deep soul searching, we decided to give RC away for free, and step away from the business of supporting it.
