So what exactly causes bounces during landing? Is it just not slowing the plane down enough or something?

Also I've been up for almost 2 days so maybe I'm just not following. Are you saying after the 2 hard bounces the plane had to take off again and then attempt the second landing, is that what you mean by having to go around? I fly more than an average person but not as much as a lot of the FTers here but I know if that was to happen on my flight it would scare the $#%&*#% out of me.
