This article seems to be based on the assumption that the term UFO implies something of extraterrestrial origin.
I suppose, in theory, an aviation accident could occur IF a vehicle of ET origin presented itself unexpectedly in the path of an aircraft.
AFAIK, that has never happened.
It would seem unlikely that a vehicle and/or occupants capable of navigating through light years of our galaxy could not find it's way safely through our skies.
The fact is that UFO's do collide with aircraft and cause damage and accidents...however they are usually identified after the collision has occured, or seconds before...

At the heart of science is an essential balance between two seemingly contradictory attitudes--an openness to new ideas, no matter how bizarre or counterintuitive they may be, and the most ruthless skeptical scrutiny of all ideas, old and new.
This is how deep truths are winnowed from deep nonsense. -- Carl Sagan
