&gt; I very much doubt there&#x27;s enough of a data recorder to reconstruct the event, even with a commercial-grade drone.<p>Why do you think that? It&#x27;s very easy to record telemetry data on even hobby level devices. In fact, it&#x27;s pretty standard if someone uses a ground station. I&#x27;d be surprised if a commercial grade drone didn&#x27;t have that capability.
