We had a lot of fun designing and launching the Led Zeppelin. It was a tremendous learning experience for me, my friends and my son. I am extremely pleased with the results of this project and all of our basic goals were met or exceeded. We knew the maximum height we could achieve was 101,800 feet given our equipment and balloon, and we got pretty dang close. With the experience and insight we gained from doing this from scratch, I'm pretty sure we can get over 100,000 feet next time. If you are inspired to attempt this yourself, let me know and I'll be happy to assist you. I have added a DIY page describing the process, including how to hack the computer firmware (and program it to take interval shots), how to set up the boost mobile tracking phone, how to avoid our mistakes, etc.Update: I just ordered more balloons... The Zeppelin will fly again. Keep checking back for more updates and (hopefully) more pictures!
