Did anyone ever escape from alcatraz?

There were several attempts but most of them were caught. Some were shot and some were found drowned. But there is a handful that their bodies were never found. So, if their bodies were never found, who knows. Maybe they did make it.

Hope this helps. :)

answer: the apache, comanche, kiowa, crow, and osage tribes are plains indians.  

the answer to fill in the blank in this question would be the word resource, it is defined as the money, material or people (since human resource is a very valuable good) that a company or a person has at disposition (meaning they can use the resource as they see fit), to be able to complete a task or achieve a goal.
