I heard a smash...
It sounded like someone threw a bottle at me. A second later my rear wheel felt "weird" so I thought that I might have run over a bottle. Turns out that smashing sound came from my wheel:

I did the same thing to an old Normandy hub... except when the flange broke, it was 4 spokes.... just went 'pop' while honking a big gear up hill. Luckily, I was about 2 blocks from home and heading back in after a nice ride...

I would say radial lacing has a lot to do with it... there is a reason that they don't recommend it on some wheels/hubs.
EDIT:
some info on the way these were laced:
EDIT:
some info on the way these were laced:
The spoke bend, where the spoke enters the hub, is solely responsible for the lateral forces and stresses. The bend also takes a hard hit from the vertical stresses. All of the shock traveling down the spoke leverages around the small point where the spoke bends as it enters the hub.

agree with Phatman,
Hub not designed for radial spoke pattern?
How many spokes?
This is from the Tune website ( www.tune.de )
flange design for radial lacing pattern and aero-bladed spokes (up to 28 hole)
- more spoke holes are for cross lacing only
They still offer the mig/mag hubs you might want to contact them
about this (if the correct lacing for hubs was used).

Last week someone posted a photo of a broken Hugi on roadbikereview.com. This week a broken Tune here. Also in a receint thread about hubs, Sheldon Brown voiced his strong opinion in favor of OE hubs, well actually, Shimano hubs.
I've been reviewing wheel info in anticipation of building a set of Campy compatable wheels for a new group I'm putting together. After Sheldon's comments I decided to stay OE and ordered some Campy hubs last night
. I'm not sure they are superior, but it's comforting to know they invented the wheel, so to speak, as far a bike parts go.

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.
