Believe me
I'm the biggest skeptic I know... well, I was prior to this. Having seen it with my own eyes while stone cold sober I can honestly say it was fucking odd... You could sort of tell from standing on Archway Road they wern't small objects far away, they were big objects in the middle distance. And you could also tell they wern't caught in the wind and appeared to move under some internal power sauce(r)... Shame that vids the only one I could find on account of it being a bit shit.

Freaked me out big time, this did. Big time.

No, you can't tell that.
Unless it overlaps with an object of known size, it is impossible to tell the size of something that is more than 18 metres away.

Look up at a plane in the sky - if you didn't know how big it is, you would never be able to guess.

We judge the size of things by the slightly different views we get from each eye. More than 18 metres away and our eyes are too close together to successfully do so.

It could be a spaceship at 100,000m or it could be a fire balloon at 19m. I know where my money is.
