Pocket Rocket is a program written for the Palm Pilot OS. It was originally written by Jay W. Ward in 1998. I have updated the files and they are current as of May, 2000. I have permission from Jay to modify the program and distribute it as Shareware / Freeware. More information is contained in the readme file that is included with this download. The Pocket Rocket program is a convenient way to bring a rocketry flight simulation program with you to the launch site. It will calculate the approximate maximum altitude of a rocket / motor combination.
