Also got one CTD this evening after several hours of flying/driving- my first with AH2, so not exactly a common occurrence for me. Occurred in heavy furball, but I do not believe I augered or was hit (was checking my six). {That last sentence shows my age: in ancient times of Confirmed Kill CTDs were sometimes associated with augers or deaths}
