Object has unwanted animation, how to remove?

Yes i’m aware 2.8 is beta/alpha.
So this might be a bug, but i’m curious how i can remove animation from the drone object seen below

There is nothing visile in the dope sheet, and a small script below doesnt have an effect either :
obj = bpy.data.objects[“drone”]
obj.animation_data_clear()

found the cause by accident it had assigned a softbody

Yep this line indicates the presence of a physics cache.
