Under Different Skies

This 50-foot concrete arrow is located off Interstate-15, in Washington County, Utah.

I don’t know what I love more: driving or flying. Both have their charms, for different reasons. If I want to explore a landscape, though, I’d drive through it, not fly over it. Taking a road trip à la Jack Kerouac is ripe with adventure; flying –at least, today, with stress.

One strange structure you’re likely to encounter, if you drove from one coast of the U.S. to the other, are huge concrete arrows.

These markers were built in the mid-1920s to help pilots navigate the airways. They were placed at the base of a set corresponding set of beacons, which illuminated them after dark. They were painted yellow and each pointed in the direction of the next beacon.

Today, these pieces of Americana are strewn across the length and breadth of the nation and can be an attraction to a passing traveler.


Climate-Change To Make Flights More Bumpy

Air travel is likely to get a lot bumpier because of climate-change, a new study suggests.

A doubling of carbon dioxide levels in the atmosphere would increase the average amount of severe cloudless, “clear air” turbulence at seven miles—the altitude at which commercial passenger jets, on long-haul flights, routinely cruise—by 149 percent.

Hop On And Fly Away … In A Taxi

Commuters in Dubai will soon be able to hop aboard flying taxis à la “The Jetsons” and take off, literally, at the push of a button. The cockpit has no pilot and no controls.

The passenger drone, capable of carrying a single rider and a piece of small luggage, can fly for 30 minutes or up to 30 miles on a single battery charge. It has a top speed of 100 m.p.h., but it’d, typically, operate at 60 m.p.h.
