Going in an airplane does not qualify one to speak, this is the expected response; exactly as described in the article above. Lolz.

"this "ridiculous response" only comes from those who have honestly not researched the subjects for themselves. Anyone who'll the spend hours on investigation of the flat earth model in images below, and videos Steem'd here, soon fall silent..."

"It's hard to see the curvature of the earth from an altitude of 7 miles or 37,000 ft (typical cruising altitude of a jetliner) but easy to see from 250 miles (typical altitude of the ISS). The line of sight from an aircraft at 37,000 feet = 235 miles. That's only about 3.4 degrees of the earth's surface."
