Flight Schedule

For anyone who would like to know when I'm leaving and where I'm going- an approximate flight schedule:

Depart Monday, Sept. 13 7:30am from Fort Wayne
Arrive Monday, Sept. 13 8:30am at Chicago O'Hare
Layover
Depart Monday, Sept. 13 11:00am from Chicago O'Hare
Arrive Tuesday, Sept. 14 4:15pm at Tokyo Narita

The flight from Chicago to Tokyo is surprisingly short-only 13 hours. I would have thought it to be longer, since the flight from LA to Osaka was 12 hours. However, because of the Great Circle ("An arc of a circle for which the center is the center of the earth. A great circle is the shortest possible surface route between two points on the earth.") it's not as long as it could be. I looked it up on the Great Circle Mapper and here's what I found:

Chicago (41°58'43"N 87°54'17"W) to Narita (35°45'53"N 140°23'11"E) is 6274 mi

LA (33°56'33"N 118°24'29"W) to Osaka (34°25'38"N 135°14'39"E) is 5742 mi

That's only a difference of 532 miles. At the average speed of a commercial airplane of 600 mph, that equals only about an hour difference. Just what my flight schedule says.
