How many enroute mid-air collisions have there been in the past century?


At least one.

I can think of at least four.
One in mid USA over the Grand Canyon. Constellation/ DC-7
One over New York DC-8/ Super Constellation
One over Yugoslavia Trident/ DC-9
One over Switzerland (or that region) quite recently

Flicking through one of my books I spotted a couple of others. Would
include civil/military accidents?
