Was flying my P3 around the building under construction when it lost signal and that was the last I've seen my P3. No return home function was initiated which it always did in similar situations before. Never regained signal. I went looking at the construction site went up to the 40 some floors of unfinished building (no security at all) - no trace of it. Nothing on the ground around the building. I was a good distance away from the building and had good video up to the point when signal was lost. There were no issues during the course of the flight up to loosing signal. My question is it possible to recover flight info if I never found the P3? Any way to find out if it crashed? Can I expect anything from DJI (an explanation) or is that a lost cause? Thank you.
