LE BOURGET, France (AP) — Here’s a look at some innovations from this week’s Paris Air Show:
JET-LAG CURE?
You know how you feel — and look — when you get off a trans-Atlantic flight? Exhausted, blood-shot eyes, swollen ankles. Partially that’s jet-lag. But partially that’s because you’ve effectively been up a mountain for several hours, with all that entails, including increased heart rate and shortness of breath.
Some manufacturers are working to reduce those effects — thanks to new composite materials that are more fatigue-resistant themselves. Currently, commercial jets fly at between 35,000 and 45,000 feet and pressurize their cabins to bring what your body feels down to around 8,000 feet.
But Boeing’s new 787 Dreamliner, which is primarily made of composites, brings you down to 6,000 feet. Normal, aluminum-built planes could be pressurized to that level, too, but they would take more of a beating to do so and would have a shorter lifespan. If you’re really rolling in it, private jets, like the new Gulfstream, will do you one better: life in the cabin is below 5,000 feet.
