A new airport (KIND - Indianapolis, IN) was recently made available on my website
http://www.buckeyediscus.com/fs2002/
With this new airport, written by Fr. Bill Leaming, I discovered another really nasty bug in Add A Gate. Luckily, it only took 4 hours to track it down and fix it. Please download the latest build(61) from the website above and overwrite the existing addagate.exe you currently have.
thanks

p.s. sorry for releasing this so soon after 60, but that was a nasty bug.
