I need your ideas/help

Ok, so I am working on a project and I would like some of your suggestions. I won't bore you with the full details of my project.

I am trying to build a list of interesting/curious "firsts". It is fine if we know the answers, that isnt the point...I just need unique firsts. For my project I am researching "firsts". Like;

a) Who was the first human to skydive?

b) What was the first mp3 song?

c) Who was the first paying passenger to survive a plane crash?

d) What was the first email message?

and

e) Who was the first cop to be shot with a bullet proof vest?


If you have any "firsts" you are curious about, please post them.

Thanks!
