September 11, 2001: 17 years of changes in civil aviation
And today the World Trade Center metro station reopens
Today 17 years have passed since September 11, 2001, a day that everyone will probably have well impressed in the memory and that marked an era on the false line of the "date which will live in infamy", when Japan attacked the US fleet anchored to Pearl Harbor on December 7, 1941. But if in that case the answer was the United States entry into World War II, the attacks on the Twin Towers in New York, the Pentagon and the hijacking of the United 93 flight led both at the beginning of the war on terrorism is an increase in safety measures on aircraft throughout the West and in the world.
Attacks that cost the lives of 2977 people -without including the 19 terrorists- and injured another 6400, men and women who were on board the four hijacked planes, or inside the World Trade Center, or to a lesser extent in the Pentagon. The al-Qaeda hitters were able to exploit the shortcomings that allowed them to enter the cockpits, since the armored doors present now have not been installed on the planes yet, which can only be opened from the inside. Without these, it was not complicated to enter and kill pilots using cutters and small knives, which was allowed to carry on board.
One day that changed the history of civil aviation, because from that 11 September security checks were intensified in such a way as to be able to identify any potentially dangerous instrument for the security and safety of passengers. The first objects to be banned were the knives, the cutters and the scissors with the addition since 2006 also of liquids limited to 100 milliliters, since the risk was that they were used explosives in the liquid state to carry out attacks against airplanes in flight. The same happened to the PCs and mobile phones, which were added over the years, for which specific rules were introduced that oblige owners to extract them from hand luggage or pockets, allowing a single control of electronic equipment that could contain or an electromagnetic jammer or an explosive device.
Security measures -which also the body scanner includes- which reduced the risk of possible attacks on airplanes in flight, but which have come after a given watershed for many reasons. Meanwhile, in New York at the Ground Zero memorial and the One World Trade Center -inaugurated in 2014- today the World Trade Center subway station destroyed by the collapse of the towers will be reopened after 17 years.
