Today was suppose to be the 31. flight of the ALTDuino altimeter with my "ALTDuino-Rocks!" rocket. Unfortunately things didn't go as planed. Upon ignition the rocket engine blew it's top resulting in a CATO (Catastrophe At Take Off) and the lose of the lower section of the rocket. I think the video says it all :-( The upper section including the altimeter escaped any damage.
