From the paper you cited: " The vehicle followed a lifting trajectory with a nominal angle of attack of 25.5 deg during reentry." 40 > 25.5 I doubt the MK1 pod was intended to be a lifting body. Particularly when it wants to go 40 degrees in *any* direction, rather than toward a hypothetically intended lifting body offset CoG.

I've found a problem with 2.6d2 on 0.90 involving radial boosters built with KWRocketry tanks This is a problem I'd always had in .25 and earlier, but before now, it only affected the hydraulic manifold decouplers. Now it seems to be affecting all of the radial decouplers. When I attempt to stage in flight, every part on the boosters experiences a structural failure and they disassemble. http://imgur.com/a/Mkgqf#0 It works fine on the ground with empty tanks. The problem occurs whether the separatrons are staging with the decouplers or not. If I use stock tanks on the boosters, I don't have this problem. KWRocketry 2.6d2 on KSP 0.90

I just tried that, and it fixed my tech tree. Many thanks.
