Can anyone explain what happened here? Took my P3A up this afternoon and videoed the local surroundings and took one photo. All seemed normal, nothing out of the ordinary as far as I could tell. Landed and sat a while without powering off battery (did stop motors). Went back up for another short flight and when I was up a ways I noticed there was no video on my screen. Brought it back down and saw an error of no SIM card. Looked in gimball and there was no card in it. I thought it had fallen out between flights. Turns out it was never in the P3. I had forgotten to put it back after last upload and it was still in USB adapter. Question is, why did all work ok in first flight and not in second flight?
