Why Do We Sing the National Anthem at Sporting Events?

On the night of September 13, 1814, Francis Scott Key, an American lawyer and amateur poet, accompanied American Prisoner Exchange Agent Colonel John Stuart Skinner to negotiate a prisoner release with several officers of the British Navy. During the negotiations, Key and Skinner learned of the British intention to attack the city of Baltimore, as well as the strength and positions of British forces. They were held captive for the duration of the battle and witnessed the bombardment of Baltimore's Fort McHenry. Inspired by the American victory and the sight of the American flag flying high in the morning, Key wrote a poem titled "The Defence of Fort McHenry."

Upon his return to Baltimore, Key gave the poem to his brother-in-law, who noted that the words fit the melody to the popular drinking song, "The Anacreontic Song." Key's brother-in-law took the poem to a printer, who made broadside copies of it. A few days later, the Baltimore Patriot and The American printed the poem with the note "Tune: Anacreon in Heaven." Later, the Carr Music Store in Baltimore published the words and music together as "The Star-Spangled Banner."

The song gained popularity over the course of the nineteenth century and was often played at public events like parades and Independence Day celebrations (and, on occasion, sporting events). In 1889, the Secretary of the Navy ordered it the official tune to be played during the raising of the flag. In 1916, President Woodrow Wilson ordered that it be played at all military ceremonies and other appropriate occasions, making it something of an unofficial national anthem.

After America's entrance into World War I, Major League Baseball games often featured patriotic rituals, such as players marching in formation during pregame military drills and bands playing patriotic songs. During the seventh-inning stretch of game one of the 1918 World Series, the band erupted into "The Star-Spangled Banner." The Cubs and Red Sox players faced the centerfield flag pole and stood at attention. The crowd, already on their feet, began to sing along and applauded at the end of the song.

Given the positive reaction, the band played the song during the next two games, and when the Series moved to Boston, the Red Sox owner brought in a band and had the song played before the start of each remaining contest. After the war (and after the song was made the national anthem by a congressional resolution in 1931), the song continued to be played at baseball games, but only on special occasions like opening day, national holidays and World Series games.

During World War II, baseball games again became venues for large-scale displays of patriotism, and technological advances in public address systems allowed songs to be played without a band. "The Star-Spangled Banner" was played before games throughout the course of the war, and by the time the war was over, the pregame singing of the national anthem had become cemented as a baseball ritual, after which it spread to other sports.

Big Questions
Where Is the Hottest Place on Earth?

The summer of 2017 will go down as an endurance test of sorts for the people of Phoenix, Arizona. The National Weather Service issued an extreme heat warning, and planes were grounded as a result of temperatures exceeding 120 degrees. (Heat affects air density, which in turn affects a plane’s lift.)

Despite those dire measures, Phoenix is not the hottest place on Earth. And it’s not even close.

That dubious honor was bestowed on the Lut Desert in Iran in 2005, when land temperatures were recorded at a staggering 159.3 degrees Fahrenheit. The remote area was off the grid—literally—for many years until satellites began to measure temperatures in areas that were either not well trafficked on foot or not measured with the proper instruments. Lut also measured record temperatures in 2004, 2006, 2007, and 2009.

Before satellites registered Lut as a contender, one of the hottest areas on Earth was thought to be El Azizia, Libya, where a 1922 measurement of 136 degrees stood as a record for decades. (Winds blowing from the nearby Sahara Desert contributed to the oppressive heat.)

While the World Meteorological Organization (WMO) acknowledged this reading as the hottest on record for years, they later declared that instrumentation problems and other concerns led to new doubts about the accuracy.

Naturally, declaring the hottest place on Earth might be about more than just a single isolated reading. If it’s consistency we’re after, then the appropriately-named Death Valley in California, where temperatures are consistently 90 degrees or above for roughly half the year and at least 100 degrees for 140 days annually, has to be a contender. A blistering temperature of 134 degrees was recorded there in 1913.

Both Death Valley and Libya were measured using air temperature readings, while Lut was taken from a land reading, making all three pretty valid contenders. These are not urban areas, and paving the hottest place on Earth with sidewalks would be a very, very bad idea. Temperatures as low as 95 degrees can cause blacktop and pavement to reach skin-scorching temperatures of 141 degrees.

There are always additional factors to consider beyond a temperature number, however. In 2015, Bandar Mahshahr in Iran recorded temperatures of 115 degrees but a heat index—what it feels like outside when accounting for significant humidity—of an astounding 163 degrees. That thought might be one of the few things able to cool Phoenix residents off.

How Does Autopilot Work on an Airplane?

How does autopilot work on an airplane?

Joe Shelton:

David Micklewhyte’s answer is a good one. There are essentially a few types of features that different autopilots have. Some autopilots only have some of these features, while the more powerful autopilots do it all.

  • Heading Hold: There’s a small indicator that the pilot can set on the desired heading and the airplane will fly that heading. This feature doesn’t take the need for wind correction to desired routing into account; that’s left to the pilot.
  • Heading and Navigation: In addition to holding a heading, this version will take an electronic navigation input (e.g. GPS or VOR) and will follow (fly) that navigation reference. It’s sort of like an automated car in that it follows the navigator’s input and the pilot monitors.
  • Altitude Hold: Again, in addition to the above, a desired altitude can be set and the aircraft will fly at that altitude. Some autopilots have the capability for the pilot to select a desired altitude and a climb or descent rate and the aircraft will automatically climb or descend to that altitude and then hold the altitude.
  • Instrument Approaches: Autopilots with this capability will fly preprogrammed instrument approaches to the point where the pilot either takes control and lands or has the autopilot execute a missed approach.

The autopilot is a powerful computer that takes input from either the pilot or a navigation device and essentially does what it is told to do. GPS navigators, for example, can have a full flight plan entered from departure to destination, and the autopilot will follow the navigator’s guidance.

These are the majority of the controls on the autopilot installed in my airplane:

HDG Knob = Heading knob (Used to set the desired heading)

AP = Autopilot (Pressing this turns the autopilot on)

FD = Flight Director (A form of navigational display that the pilot uses)

HDG = Heading (Tells the autopilot to fly the heading set by the Heading Knob)

NAV = Tells the autopilot to follow the input from the selected navigator

APR = Tells the autopilot to fly the chosen approach

ALT = Tells the autopilot to manage the altitude, controlled by the following:

VS = Vertical Speed (Tells the autopilot to climb or descend at the chosen rate)

Nose UP / Nose DN = Sets the climb/descent rate in feet per minute

FLC = Flight Level Change (An easy manual way to set the autopilot)

ALT Knob = Used to enter the desired altitude
