This is so funny... Firstly,

You are not getting any comments on it because, first of all, you did not put any time into your original post...".
He then apparently attempts to rectify this by posting the following tidbits over the course of
seven posts—out of 26 so far LOL:
• What is it about that video that was so impressive to you that you rushed to this site in order to post it?
• It is obviously a lens effect that is causing the curvature
• I am sure that you will try to deny what I said
• I am not sure if you only see what you want to see, or if you are simply lying
• Oh, wait, it is just another assumption that RE'ers are trying to pass off as evidence
• Thanks, so I see that know one actually measured this, it was just calculated assuming that the Earth is round
• Without actually measuring the distance from one tower to the other, then it is just calculated and done so assuming the Earth is round...
Apparently
jroa—who should know better as a moderator—considers this sort of dross to be meaningful content that adds something of interest to the thread. And yet
Pongo reckons the initial posting of this interesting video—well, interesting to REs at least—was "low content"! Bizarre.
It's actually a very interesting and technically well made video, and particularly interesting are the construction/engineeering details and the still shots on their site. Anybody with a genuine interest in astrophysics and aeronautics should be keen to see this sort of amateur stuff, and it makes one wonder why the flat earthers don't carry out a similar experiment—making sure to utilise a 50 - 55mm lens of course LOL. Difficult to determine all-up costs, but probably sub-$20K. Also of interest was the decreasing sound levels as the atmosphere thinned out towards the 121,000 ft altitude. And at this altitude, the curvature of the earth is easily visible, with the geometric horizon 430 miles (685km) distant.
It's a pity to see a well-documented, amateur project such as this treated with contempt by the flat earthers; then again, legitimate science is their enemy isn't it?
