Strange Crash with HyperSpectral Camera

I was wondering if someone could take a look at this log and let me know what all went wrong. The copter was flying beautifully since its deployment into the field until this flight. Specs of the platform are:

1100mm Frame
Quad Copter
28*9 Props
70A ESCs
10s2p 10000mAH LiPo Setup
1kg payload

Other than the radio kicking out first, not sure what went on that led to this crash. The log can be found here:
