Balloon Track Description

Balloon Track is a small but powerful application that uses data provided on the internet to predict the track, range and bearing of a high altitude balloon flight to the landing site. A while back (1990) Bill Brown, WB8ELK, was contacted by our original group of hardy volunteers and ask to mentor us on setting up a balloon flight. He came through in a big way. One of his most helpful contributions was BALLTRAK.BAS, an Basic program that would help us predict the touchdown of our payload. This program was used as is for the first several flights. But, I soon became a bit frustrated with the user interface and so wrote a "shell" to surround that code in a more friendly environment. The result of that effort was ParaTrak.EXE, a DOS program written in QuickBasic 4.5. It has served me well over the years. On one occasion we were expecting Gil Moore to launch a balloon over Utah, and have it fly to Colorado where we would issue a cutdown command. In response to this, I added a "Drop" mode, whereby the user could enter the local winds, and ask for a prediction based solely on the descent phase of a flight. Knowing the location of the balloon at cutdown, we could then predict a touchdown point. A while later we flew our first ZERO pressure flight. This balloon ascended to it's destined flight level, and then floated there in the winds at that altitude until a cutdown command was issued. In response to this I added a Float routine and FloTrak.EXE was born. There were still some user interface problems I hadn't tackled and I decided to go into the program and "fix" it. But, upon looking at all that scattered unreadable code, I decided it was time to rewrite the program. Balloon Track for Windows is the result.
