The Chinese use drones equipped with miniature flame throwers to burn debre off power lines so I’m thinking the lines, if not directly contacted.
It would be an assumption that all the lines were on the exact elivation.
It has probably been mentioned but flight data can be retrieved from go4 app and Uploaded to airdata for some really detailed stats on your flights.
Not sure what a collision looks like on the data. On airdata there are several categories from which to choose, one being notifications. One of my flights today that I purposely let my battery run down to where on one cell had 8% remaining at a good distance from home. The last reading I received was that I was 18 feet off the ground but I know that to be false since my last know altitude before losing connection was 1 meter AGL and in landing mode. That being said, you mayormay not be able to unravel your crash via your controller.
