There seems to be a disconnect here. I was trying to be helpful - not trying to prove anything one way or another. You asked for numbers to this question:
"The tech advancements are responsible for an increase in midairs."
The information I took the trouble to locate addresses the latter half of that claim: "an increase in midairs."
The issue is determining whether that half of the claim is even accurate - so do you see any trend in the numbers that supports the claim that there is an increase in midairs? I don't.
The Nall analysis says that ~50% of midair collisions happen in the traffic pattern and that 80% of midair collisions happen within 10 miles of an airport. Over 80% of midair collisions involve a fast plane overtaking a slow one. Only 5% from head on angles.
Collisions on airways doesn't seem to have come up enough for the Nall analysis to note the stats on them.
