"So many"? I just quoted the part of the article that says it's 1-5 people per month with "possibly really anomalous" reports. And no, it's neither clearly "real" nor "air-borne". What gets recorded on instruments, including video, is an imperfect reflection of what's happening, and to think that because something has been recorded means it's real is not accurate.
Kirkpatrick doesn't count those flying spheres as "really anomalous". I don't know why... Your "It's not clearly real or airborne" is interesting. Technically, you are correct, but it's a remarkably absurd stretch here. The level-headed approach would clearly be, to assume it was real and attain better data.
Why are these videos always so grainy, out of focus, and otherwise unclear? Perhaps when clear and unambiguous video is captured there is no mystery…
