I just jumped 8 inches in the air, also achieving weightessness. Please
inform CBS.

Film at 11.

Ted posted: "If this is a quiz, George, the answer is: It isn't
weightless, it's in free

I'd observe that both answers are correct.

Glenn chimed in with: "It was only in
free fall when it was on a geodesic path outside of the part of the
atmosphere where enough atmospheric density could cause significant
drag."

Even in outer space -- say 100,000,000 parsecs away, there is SOME drag
due to encountering matter. In a strict sense, then, one can never attain
"free fall." Maybe 100,000,000 years of stability -- but then ... .
