1. When the article refers to the shuttle columbia, Tufte explains how NASA created a series of powerpoints in a life or death situation. I don't really understand why they created powerpoints. If someone was in a life or death situation shouldn't NASA get together and have a meeting about the factors they could do, beside send everyone a powerpoint email about the situation?
2. Tufte constantly refers to stupid people making powerpoints in serious cases. He stresses that powerpoints should be presented, rather than printed out or sent through an e-mail. NASA never created formal documentation about the shuttle Columbia; instead they made powerpoints. My question is: why didn't people make a formal document? Why did these people make a powerpoint slide when they could have easily written up a document? I don't understand why people would consider a powerpoint slide a documentation for a specific period, even though a powerpoint is meant to be presented rather than used for hard copy.
