That's quite something. Although it didn't look broken. Could be failure of the bolts or just not assembled properly after the flight to Tokyo. Should have shown in the training though...
Yeah you can definitely see it's broken in the video Hoke posted. Shame the resolution isn't a bit higher so you can see inside the component. I'm fairly sure it's a 3D-printed thin-wall titanium part with a lattice inside; I was interested to see what kind of lattice pattern they'd used!
Aussies not get the recall notice on those Argons?
