Technically, that is not actually a USA flag. The USA flag always has the blue field to the left. But people do tend to put a "reverse flag" on aircraft etc. to give the impression that the emblem is a real flag being pushed back by the wind. You can bet on the other side of the aircraft is a real flag emblem, oriented as usual.
Although at first glance it appears wrong, the flag on the shuttle Orbiter is not truly backward. The regulation for displaying a U.S. flag on a national vehicle states that the star field must be positioned at the front of the vessel (the nose cone end of the shuttle), as if the flag were "flying" along the side of the ship. This causes the flag to look as though it were backward on one side of the Shuttle.
If the soldier were carrying a flag, the flag would appear "backwards" when viewed from the soldier's right. Thus, the right side patch is backwards. It's the same reason that the flag is painted backwards on the right side of airplanes and other vehicles.
The flag is worn with the appearance of being backwards on soldiers RIGHT arm to symbolize early American armies which had a flag carrier holding our flag high (which looks backwards from one side while correct from the other). The backwardsflag signifies this and gives the perception that every soldier is carrying a flag. Left arm patches are correctly laid. It is worn backwards to make it look like a soldier is marching into the wind carrying a flag and the wind is blowing into the flag. I hope this is more understanding. This is the same reason for astronauts.
"Forward deployed"
Depending on which way it's facing. The Stars of the flag should be moving forward.
to show that they are American aircraft
I heard its backwards cause during the civil war..the cavalry would ride into battle with the American flag and with the direction of the horse and the wind,the flag appears backwards.that's why the troops wear it backwards.for pride
Adorning all American spacecraft and most aircraft is an American flag which appears to be backwards, or inverted along the Y-axis. This is an intentional design, with the following concept in mind: 1) Imagine an American flag, correctly represented with the stars on the upper-left quadrant, suspended correctly by a flagpole on the flag's LEFT side. 2) Imagine the wind suddenly reverses, or the flagpole moves to your visual right, and the flag is now suspended to backward, attached to the flagpole on the flag's now RIGHT side. Because the flag would appear backward on any vessel moving forward (flag against the wind,) and American vessels never retreat, it has been a unique point of pride to paint our science and military vessels as "forging ahead" with a backward-facing flag.
Neil Armstrong was working for NASA and working for the USA so he only had an American flag and he wouldn't have a Union Jack
You see the American flag on every government building, inside many government offices. In every US miltary base, however small, on all American ships and aircraft and on many American homes.
In wartime the flag is worn backwards to show advancement.. take the flag and put it on a flag-pole and run at the enemy.. it flies backwards.. Hope this helped Flying the flag upsidedown is a sign of duress. The idea being that your enemies would not know which side was up but your friends would and would come to your aid.
The flag is not really 'backwards' on their shoulders, the flag is 'flying' forward as they move forward. Note also it is only worn on the right shoulder. "The U.S. flag embroidered insignia is worn so that the star field faces forward, or to the flags' own right. When worn in this manner, the flag is facing to the observers right and gives the effect of the flag flying in the breeze as the wearer moves forward." per military code.
The flag is not worn backwards but is worn, "facing home." This is a regulation that was ordered by the Department of the U.S. Army, Army regulation 670-1.
