On anecdotal ... you are using a generic presumed usage. I use one that accepts firsthand knowledge or experience or scientific investigation as not being anecdotal as in the following definition from Encarta:
Encarta® World English Dictionary © 1999,2000 Microsoft Corporation.
an·ec·dot·al [ànn?k d?t’l] or an·ec·dot·ic [ànn?k d?tik] adjective
1. based on anecdotes or hearsay: consisting of or based on secondhand accounts rather than firsthand knowledge or experience or scientific investigation.
So, to the pilot it's firsthand. To you and me it's anecdotal and useless.
I've also pointed out the value of quality anecdotal evidence in the pursuit of science ( medical case studies ), for which anecdotal evidence is the norm. So even if you reject the Enacarta definition, you can still find evidence for anecdotal evidence being used to further our knowledge and understanding, and contribute insight for progress where hard science is concerned.
And it was those medical studies that we weren't going to compare to because you're comparing apples and oranges, as was explained to you upthread.
For the radar return from the object the jet was chasing, the radar is what alerted the base to the presence of an unknown target. Jets were scrambled, but before the jets made visual confirmation, the object faded off the radar. This was an early radar system, so they didn't know if the UFO had faded up out of range, or gone "under the radar". So they started the search high, then moved down, ( this is logical as it allowed the pilots to either intercept or gain the high ground right away. If it was below, then they had the "upper advantage" ... which is how it turned out ... ).
So, that's a no, the object that the pilot claims to have seen did not appear on radar.
Were you conflating the two? The earlier radar return and the later claimed sighting by the pilot? It's very easy to do when you aren't thinking critically. Fortunately we are thinking critically so the two are separate and distinct.
As the search progressed to lower altitudes, one of the pilots spotted the object below the radar and took up pursuit by going into a dive. So there was a short period of time between the radar contact and visual confirmation.
Exactly! Can you see how other people would merge the two events together in their mind and relate them erroneously?
Although the gap between the radar contact and visual confirmation existed, the two actions are so closely connected, and the flight characteristics of the UFO spotted so similar to the initial radar returns, that it is reasonable to assume that the UFO was the same object that was initially tracked on radar a few minites before.
Yes, I guess you can see how they would erroneously do that. So, you've decided to not apply critical thinking skills here?
NOTE: Consider the term "visual confirmation". Why do you hear that term used? Might I propose that it's because visual confirmation verifies the radar? What does this imply about the data provided by radar compared to data provided directly by a pilot in visual range? Certainly we can see that it has value ... moreso than the radar data alone.

But he didn't have a sighting on a radar target. Do you see the difference?
