Travel in time and space



One of the fun parts of international air travel today is being able to follow the airplane’s path via a map projected on a video screen. Our travel to Singapore was fascinating in that we covered much of one-quarter of the globe in that one journey.

When we took off from Dulles airport near Washington DC, we didn’t head west, as I expected, but north over Canada. After several hours we swung northwest and passed over Alaska above the Arctic Circle. Then, crossing the International Date Line (tomorrow just became today), we turned south over Siberia and plunged down toward the equator. Singapore is effectively just over 1° north of the equator. This means that our flights, in a 23-hour period (but 2 days on the calendar), covered the equivalent of one-quarter of the globe – halfway around the world from east to west, and about half of the globe from north to south, since we went from the Arctic circle to the equator!
