Same thing happened to a friend of mine who had a radially laced Nuke Proof hub. The funny thing is that the bike was in his bedroom and he was fast asleep when the hub exploded.

I concur, that's not a good candidate for a radially laced pattern. Regardless of published claims in manufacturers literature, the evidence you just provided proved it wrong.

DT240 hubs are made for radial lacing. Look how much more material is above the spoke elbow on the flanges.
