Tweak, I hadn't been following this thread, but went back to read your post on this. What confuses me is that you say the shockcord had more drag than the drogue, so that that two rocket pieces at the ends and the drogue in the middle formed a big M. So, are you saying the the drogue did not deploy and was hanging upsidedown from the shockcord? Because if it was open, then it would seem it would have to be pulling up on the shockcord.
Or is it possible the winds were pulling the shockcord horizontal, creating a horizontal "M" as viewed from the ground and yanking the rocket pieces together.
Just curious.
