I summarised the story told by the flight data in post #2 and gave a link you can click to see a short version of that data.Bird tips drone.... drone hits ground... battery ejects... sudden power loss?
The data is being recorded each 1/10th of a second and ends with the drone 346 feet above the ground, in stable flight.
There's no hint of anything bumping the drone and no data for the fall to the ground which you would see in the scenario you described.
The sudden power loss happened 346 feet up.
