The steel curtain is now up in Detroit, USA.
The steel curtain has been in place since 1952, but its first appearance was on March 11, 1952 when it was installed by the US Army at Fort Drum, New York.
In 2017, the curtain was installed at the Detroit Lions Stadium as part of the stadium’s new stadium.
A new steel curtain now stands at the US National Football Stadium in East Rutherford, New Jersey.
It is expected to be the tallest building in the world when it is completed in 2020.

They were able to use the curtain to protect them from incoming artillery shells and were able also to hide themselves from the enemy.
The curtain was used during World War II and in the Korean War, when the curtain’s thickness was about 2.5 meters.
Today, the US military still uses the curtain.
The National Guard and the US Department of Homeland Security have also used the curtain, which is the only steel curtain in the United States.
The Army is not using it for its own military use, as the curtain is only used in a controlled environment.
The Pentagon has asked for help from the public to help it remove the curtain from the building, as it has been known to cause injuries to soldiers.
