A flat-earth conspiracy theorist took a spirit level on a plane to “prove” the earth is flat. He also filmed it... Presumably in the name of science?
YouTuber D Marble flew from North Carolina to Seattle to see if the pilot would dip the nose of the plane to “compensate for curvature”.
He says in the video:
I recorded a 23 minute and 45 seconds time-lapse, which by those measurements means the plane travelled a little over 203 miles.
According to curvature math given to explain the globe model, this should have resulted in the compensation of 5 miles of curvature. As you'll see there was no measurable compensation for curvature.
D Marble has gone viral thanks to his experient.
Not for the reasons he was hoping for though...
Here's the video:
