"We tend to forget that happiness doesn’t come as a result of getting something we don’t have, but rather of recognizing and appreciating what we do have.”
WACs at Camp Shanks, New York in Feb 1945 shortly before being shipped out to Europe. They would be the first all-black WAC unit to go overseas to aid in the war effort.

Because there’s less air! OK, so there are two reasons airplanes have to expend fuel. First, to keep themselves off the ground and second to keep themselves moving forward.
Lots of air around helps planes get lift, but planes can generate more lift in other ways…by having larger wings or traveling more quickly, and more quickly is what we want…so let’s just do that! Energy expended to move the plane forward is only limited by the amount of drag on the plane and the only way to reduce that is to make the plane more aerodynamic (which we’ve done pretty much everything we can to achieve) and by making it fly through thinner air. There are far fewer air molecules at 30,000 feet than at sea level, so the plane is literally running into fewer molecules and thus it can travel more efficiently.
Of course, at a certain height, planes have to have such large wings or travel so fast to generate lift that this efficiency gain is no longer productive. The engineers have done the math and found the optimal height for efficient travel and designed planes to operate best at that height. Yay engineers!

steve rogers is american the way ‘born in the usa’ is american: realistic and open-eyed and unflinching in the way he regards his country, aware of its flaws and willing to critique them, always on the side of the underdog and the left behind, and often fundamentally misunderstood by the right because of some well-placed stars and stripes.
