Alcatraz is a prison on an isolated island in the United States. How did the criminals there escape from prison?

People in Alcatraz Prison use some hard materials, such as coins and nail clippers, to dig up the wall, then use some other materials to make their heads look like them and put them on the bed to cope with the patrolling guards, and then climb onto the roof to escape. It can be said that these criminals who escaped from prison are very smart and capable, because only three people escaped from prison.

Alcatraz? The island, formerly known as Alcatraz Island, was once an important military site in the United States, but it was later used as a prison for some special reasons. Because of its remote location, the island is surrounded by rocks or very cold sea water, so all the felons in the United States are held on this island. Later, because some films were shot on this island, it is said that this island has gradually become a tourist attraction in San Francisco, USA.

According to the records of Alcatraz Prison, three prisoners escaped from prison successfully. They are serious criminals who entered the prison at different times, but the prison records only recorded that they successfully escaped from the island, but did not say whether they really survived after escaping from the island. Three prisoners used some hard stolen items, such as coins, spoons and nail clippers, to dig up the wall in their cell. After digging it out, they made some fake walls out of some newspapers to fool the patrolling jailers. In addition, they made things like heads out of cotton, hair and plastic, and then put them on the bed to make the patrolmen think they are still in the cell.

When everything else is ready, these criminals will use other stolen goods to make some inflatable valves and bellows to complete the means of transportation they want to use after they escape, so they escaped from prison by their own wisdom.
