Help, Lost Cube Orange at sea!

Hi… during a thermographic service, today I lost my drone at sea with Cube Orange and Herelink onboard

I suspect a cell crash because after just 10 minutes of flight (autonomy over 40 minutes) the drone inexplicably went to land in the open sea (the criterion set is: Warning in Low Level Battery and Automatic Land in case of Critical Voltage -NO RTL-)

For insurance reasons (Kasko) I need to understand the ditching point.

He asks if there is a way to obtain the data of the last flight in the Herelink logs

Thank you

@Michael_Oborne

Any logs in herelink that could help here?

Did you have logging turned on in QGC?
