This is the fifth of five launches we accomplished. We had to design and launch a model rocket for my Intro to Aerospace class at Georgia Tech. The objectives for the launch were as follows: Apogee of 300 feet Flight time of 20 seconds Descent rate at touchdown of 12 feet per second. We launched one last time, despite having a launch with an apogee of 311 feet, in attempt to get closer in altitude or the other attributes. The altimeter recorded, but appeared to be ill-calibrated (negative 60 feet starting altitude, negative 60ish landing altitude), so we couldn't reliably use these results.
