not sure if this is a bug.
took a jug to P17, dove on city from the west (sea side). puffs of AAA appear. i rocket and mg city, zoom up and over the bluffs, with AAA puffs still following me. as soon as i'm over bluffs, i drop down to ground level, continuing east. the bluffs are now between me and city/airfield in LOS, but AAA is still bursting right off my six. not overhead, but right off my tail.
seem to me if that is happening, the AAA is shooting thru the ground
