The horizontal and vertical poles were each made of one-inch aluminum tubes in two telescoping parts, anodized with a gold color. Due to the limits of the astronauts' spacesuits, the total height of the flagpole was limited to their 28-inch (71 cm) minimum and 66-inch (170 cm) maximum reach. The flag cost $5.50 and the tubing cost $75. [2]
The basic wigwag signaling motions [1] The wigwag system consisted of a signalman waving a single large flag or other display device in different motions sequentially. At night, a lamp on a pole could be used, or over short distances the signalman might hold a small disk.
Telescoping in mechanics describes the movement of one part sliding out from another, lengthening an object (such as a telescope or the lift arm of an aerial work platform) from its rest state. [1] In modern equipment this can be achieved by a hydraulics , but pulleys are generally used for simpler designs such as extendable ladders and amateur ...
In the 1850s, U.S. Army Major Albert J. Myer, a surgeon by training, developed a system using left or right movements of a flag (or torch or lantern at night). Myer's system used a single flag, waved back and forth in a binary code conceptually similar to the Morse code of dots and dashes. [ 4 ]
Since 26 December 2021, the tallest free-standing flagpole in the world is the Cairo Flagpole, located in the New Administrative Capital, Egypt at a height of 201.952 m (662.57 ft), exceeding the former record holders, the Jeddah Flagpole in Saudi Arabia (height: 171 m, 561 ft), the Dushanbe Flagpole in Tajikistan [5] [6] (height: 165 m, 541 ft ...
[1] The position of honor is centered or to the flag's own right (a viewer's left). When carried in single file (such as for color guard), the flag of honor leads. When two poles are crossed, the position of honor is the flag that ends on the left side from the point of view of an observer (the pole will therefore end on the right).
