I had just my Phantom crash into Detroit River. I am not positive what really happened because I lost it.
I am wondering if wind could have made it drop straight down.
There was a gust of wind. GPS mode on. Fresh battery - ~30sek. into the flight. Leaned quite a bit into the wind.
I just had a crash that seems similar, although I lost both Phantom and GoPRO 3 hero black in the Detroit River.
I had been flying it only for a few days now but felt confident in controlling it.
It was updated, GPS was on and IOC set to manual, I waited until there was only green light flashing...
