WHAT THE FISH TACOS 2: The Taco's Exile

Plane speed is not measured in kmph, but in knots

The rate of travel over the surface of the earth is actually completely irrelevant for a plane. Instead, we measure its 'airspeed,' the speed of the plane vs the oncoming air

For this reason, planes can sometimes reach extremely high apparent speeds over a certain distance

Also for this reason, small planes that fly at low speed can, in some conditions, sit completely still while flying. It's a really good bit

Planes can go really high. Many commercial planes can cruise at around 40,000 feet

While 40,000 feet is very high, the 'edge of space' (as defined for legal reasons) is around 330,000 feet

For jets, which use exhaust from turbine engines to fly, the efficiency gain from flying at high altitude where the air is thin is so great that even on short flights it's most efficient to climb as high as practical before descending

For turboprops, which use turbine powered propellors for power, more air density increases efficiency. That's why they're usually smaller and used for shorter flights

An aerodynamic stall is when a plane is no longer able to maintain lift and will fall out of the sky. For most purposes pilots use speed to approximate when it would happen, but really, it's when the angle of attack (the angle of the wings into the air) becomes too high and air separates from the tops of the wings

“For most dialogue, use a comma after the sentence and don’t capitalize the next word after the quotation mark,” she said.

“But what if you’re using a question mark rather than a period?” they asked.

“When using a dialogue tag, you never capitalize the word after the quotation mark unless it’s a proper noun!” she snapped.

“When breaking up a single sentence with a dialogue tag,” she said, “use commas.”

“This is a single sentence,” she said. “Now, this is a second stand-alone sentence, so there’s no comma after ‘she said.’”
