The superheroes from New-York city

On september 11th  2001 an attack terrorist has taken place in New-York city. The twins towers of the world Trace Center collapsed. Many people were affected by this event: both physically and mentally . People had difficult to believe that it was the reality because they have never seen this except in the science fiction movies .That is why many artists are interested in this large-scale tragedy.

It is difficult to image a more dangerous situation since the 9-11,  when two planes crashed into the two towers,then these are slumped.The firefighters went in this towers to save lives although there was lot of rubble and smoke. The FDNY were able to help people who injured but many people are died or wended too. Others who seen this scene had very scared and panic-striken because some  families have lost one person or more in that attack .They were helped by Police. It's for all these reasons people have called the FDNY " ground heroes " after this event.
That's why we pay them a real tribute.

Actually, they are capable of switch off fires and save people in danger. In other words,  FDNY are very courageous and strong because this job is very difficult.

In conclusion, these people are as very heroic as traditional
superheroes who exist in films because they save lives at many people  in the real word event though it was difficult for them because the firefighters put their lives at risk.
All this to say finally , you can call the FDNY the captains of America all over the U.S.
