We just had a fun weekend at Doonside. The weather was perfect for launching and so we set up Acceleron Vb with all the modifications for the next test flight. About 10 seconds from launch the booster exploded on the pad. It was quite an impressive boom to say the least. One of the spliced bottles came apart. Although quite a few pieces came off, surprisingly there was little damage caused to the booster and sustainer. Repairs are already under way to get it ready again for the next flight.
We got good high speed footage of the explosion (over the years we have learned to keep the camera rolling while pressurising). Photos and video will be posted on the main website soon.
Other than that we ended up flying Axion V three times with foam and all the flights went really well with good onboard video and altimeter data. We were a little dissapointed that Acceleron V did not get to fly (as a cohesive unit :) ) this time, but at least the repair bill will be under $5.
