DJI 0182 footage of Sunday Crash 4k 60fps

I took off and was flying at about 4m above Lake Mallacotta, In Normal Mode, I went down instead of up and it clipped the water, went up, kept flying, overheated and came home. I rinsed with fresh water and dried it. The battery did not appear to get wet. The water was salt. I thought in Normal mode it could not fly into the water.
Update: had Care Plan Air 2, damage was $1,300 was away for 4 weeks (Aust post took 3 weeks of that) Have a new drone now :)
