Near miss can be a confusing phrase, but it means a miss where the objects (or planes here) were very near each other. With that context, a near collision wouldn’t make sense as there’s no way to have a collision where the objects are just near each other (as opposed to contacting each other).

I’m confused on why your math is showing it’s going to cost $5.5M/year over the nearly 2 year course of the program.

E: ah you’re probably just extrapolating the continued cost if it ends up being renewed another year after this.
