I was part of the Wing and ~2km away when that unfortunate incident happened.
I was aware that the rest of the Wing was locked on a CMDR all the time.
He was displayed Hostile to the Wing probably due to hitting one of the Wing members with stray fire since a few Minutes.
Seen that alot in the Kaushpoos HazRES and it happens easily :/
I guess that contributed to the incident...
By the time I could hammer the CeaseFire! line into the Wing comms, the damage was already done
(personally I always try to deconflict from other Wings or Groups of Players in those busy HazRES if possible - since I'm running a 3x PA equipped FdL in the Kaushpoos BH CG, I'm used to being
very careful before engaging anything)
