Half Mast & the Invisible Flag of Death.
The tradition of flying the flag at half-mast began in the 17th century. According to some sources, the flag is lowered to make room for an "Invisible Flag of Death" flying above. However, there is disagreement about where on a flagpole a flag should be when it is at half-mast. It is often recommended that a flag at half-mast be lowered only as much as the width of the flag. British flag protocol is that a flag should be flown no less than two-thirds of the way up the flagpole, with at least the height of the flag between the top of the flag and the top of the pole. It is common for the phrase to be taken literally and for a flag to be flown only halfway up a flagpole.
When hoisting a flag that is to be displayed at half-mast, it should be raised to the finial of the pole for an instant, then lowered to half-mast. Likewise, when the flag is lowered at the end of the day, it should be hoisted to the finial for an instant and then lowered.
History of Flying Flags at Half-Mast.
Most historians agree that the earliest references to this event date back to 1612 when the captain of the Heart's Ease perished as the British ship was heading to Canada. Upon returning to London, the ship's flag was at half-mast. Scholars believe that the ship's flag was lower the width of one flag to make room for the invisible Death's Flag.
U.S. Flags and Flying Half-Staff.
The United States has strict regulations that are in place when it comes to flying national flags at half-staff. For various members of the government, for example, the time frame varies. Upon the death of any president of the United States -- current or former -- the flags fly at half-staff for 30 days. The death of the current chief justice, vice president or speaker of the house means U.S. flags will fly at half-staff for ten days. Other governmental officials such as former governors, vice presidents and cabinets secretaries have national flags lowered from the day of their deaths until the day they are interred.
There is another naval theory that flying a flag at half-mast was a sign of surrender. By lowering one's own flag, you left space for the victorious ship to fly its flag above yours.
Note that an Invisible Flag of Death or Death Flag has never been created and is symbolic.
