Q, If the earth is round then why could I stand on a salt lake in Australia and see people 10 miles away using a telephoto lens? And why if it’s 5,171 miles from Perth to Johannesburg do planes fly 5,884 to Bahrain to refuel first? Why did a flight from Bali to LA once make an emergency landing in Anchorage and not Honolulu, which would be on the way?
