Default Quito, Equador

Setting out in an aircraft at noon from Quito, about 1km North from the Equator, at a speed of 1669.8km/hr to the West and following the line of the Equator.

After 24 hours, the 40,075km journey will be complete representing one circumference of the Earth.It will also cover all those longitude meridians which are made up of time and distance differences corresponding to 4 minutes clock time for 1 degree of longitude.

This is how easy logic and reasoning is - a crucial component in astronomy.

An aircraft circling West along the Equatorial latitude for a year at the speed of the Earth's rotation would still experience a single day/night cycle even though it arrives back at the longitude of Quito after a 24,901 mile/ 40,075 km journey in 24 hours.

This corresponds to the orbital day/night cycle experienced at the North and South Poles each year where only one sunrise/sunset happens on the Equinoxes. This rotation turns the surface parallel to the orbital plane with a maximum rotational speed of 68 miles/per day.
