If all midair collisions were eliminated...

And I forgot to mention Mode S TIS (which is not the same as ADS-B TIS-
B). Which is SSR derived traffic position sent over Mode S to each TIS
capable aircraft. Only available where there is terminal radar with
TIS support. Area radar would update too slowly, so it's limited to
terminal radar coverage and then only if that terminal radar facility
has the extra smarts to do TIS. The TIS ground processor calculates
threats to each aircraft and uplinks that to that aircraft over Mode
S. Obviously the threat aircraft need to have Mode C or S transponders
and be within coverage of that terminal radar. /snip/

Which reminds me: I fly out of a civil field in a notch of the zone
round a military base - where a digital radar upgrade has recently
appeared. I notice that with my mode C active, I seem to be able to
hear an interrogation as a click as well as see a visual interrogation
flash.
These days, I don't get a repetitive once a revolution style
interrogation, but rather a string of clicks when I am inbound (i.e a
threat to military types which do have squitter) in my headset tuned to
the CTAF
