In which sense? We have a naturally occurring phenomena that exhibits the same characteristics as many UFOs. Thus, any radar data showing such characteristics cannot in any way be evidence of ET.
There are major differences between metallic objects and those of natural phenomena, which is why radar controllers will tell you they can differentiate between the two. Besides, radar have filters because radar operators can't afford to be distracted by natural phenomena clutter on radar scopes when they are controlling a number of air traffic in close proximity of one another in high-density airspace, especially during precision approaches.

Sure, but a wrong explanation doesn't make the sighting any more credible in itself. They saw something, they just don't know what.
According to the pilot, he encountered a
"gigantic spaceship." Weeks later another commercial aircraft and an Air Force tanker encountered the same object as well. In fact, the description made by the military aircrew was simillar to that made by the JAL aircrew, which was described as a
"gigantic spaceship." Radar data confirmed that particular UFO was in fact,
gigantic and
maneuvering around and trailing the aircraft.Check out the news broadcast at the latter half of this video.

Pilot Visual Description
"We were just above the bright city lights and we checked the pale white light behind us. Alas! There was a silhouette of a gigantic spaceship.
So in that regard, the UFO was close enough to where the aircrew visually identified the UFO as a
"gigantic spaceship." QUOTE
ATC Transmission
5:24:50 AARTCC - JAL1628, do you still have, uh, visual contact with the, ah, traffic?
5:24:53 JAL1628 - Affirmative. Also, [4] we [have] radar contact, ah... (unintelligible; broken transmission).
5:25:02 AARTCC - JAL1628 heavy, roger, sir. I'm picking up a hit on the radar approximately five miles in trail of your six o'clock position (i.e., behind the plane). Do you concur?
:39:35 AARTCC - JAL1628 heavy, roger sir. The military radar advises they do have a primary target in trail of you at this time.
5:39:32 JAL1628 - Ah, say again?
5:39:35 AARTCC - JAl1628 heavy. Military radar advises they are picking up intermittent primary target behind you in trail, in trail I say again.
So, here is where not only the FAA confirms the UFO tagging along with the B-747, but the military confirms radar contact of the UFO as well, so it is clearly obvious that particular UFO was NOT Mars nor Jupiter.
Eventually, Phil Klass and CSICOP found that no planet of any kind were involved either and that natural phenomena played no part as well.

It is a UFO, no more, no less, and pinning other labels on it is pure speculation. You can say ET and I can say atmospheric something.
But, it has already been confirmed from atmospheric and scientific analysis, including the nature of the radar contracts and aircrew visual accounts, that natural phenomena played no part in this encounter.
You can say, "atmospheric something," but the facts do not agree, nor does Mr. Reality!
