How long does it take to fly completely around the earth in a plane?
Well the average commercial jet liner travels about 550 mph and the earth is somewhere around 26,000 miles in circumference. If you incorrectly assume it could make the trip without refueling it would take over 47 hours. (A large commercial jetliner has a range of about 5,000 miles so you would need to land and refuel several times). The record time set for a non-stop around the world flight was in a military B-52 in 1980 at 42 hours 23 minutes. It was refueled in flight and is not an option for commercial aircraft. The solo non-refueled flight record was by Steve Fossett and took about 67 hours.
