The absence of radar data doesn't really say much anymore. I've been reading about some of the experiments they are doing in defense labs with light bending to produce invisibility.
Our obsolete stealth technology reduces the radar cross section of a bomber to that of a seagull.
Radar works at airfields for what we want it to do, which is track heavy passenger aircraft.
It's funny, because in places like Russia, Mexico, Norway, China, and Japan, there isn't even a debate about the existence of UFO's. Plenty about what they might be, but zero about the fact they exist.
The FAA. That's an agency with credibility.
Invisible from human sight from a single line of view, but O'Hare Airport probably has a phase array or multiple source radar system that couldn't easily be fooled in such close proximity to the terminal.

There is no doubt, that UFO's exist, what they are is always the question. Could this have been man made, by a governmnet? Better chance of that than coming from another planet, but if our government says they have no proof anything other than a cloud existed, and we as citizens have nothing physical to offer ourselves, it simply goes down as a UFO, and under the circumstances the most logical explanation would be clouds, IMO, as the one known undisputed fact is there was an atmospheric condition at the time.
