At that point, I could hear it but not see it yet. I had a straight flight in, so just kept it going forward and gave it 60% altitude stick, which was totally gut feeling. I'm glad I've flown on auto landing before, so I kinda knew how much to give it, but i was really guessing. Here's what HD shows for the last status in the log, last connection was at point "I" and that shows i was 1,728 ft feet away. I'd say that was about 30 seconds, maybe a tad more. The app never came back, it actually rebooted my tablet entirely and i was landed before i could try and restart (and i didn't want to take my thumbs off the sticks cause it was so close). Most of that 1700 feet was completely blind, just hearing it .. maybe the last couple hundred feet I finally saw it in the sky.
The camera on the aircraft kept recording the whole time, but when i caught it the battery was definitely not powered on. I'm going to try and put the telemetry data onto that video and share it.
