Contact Form Rocket Take Off on Submit

I have a rocket graphic and a cforms contact form (using Wordpress) overlayed over the top of the rocket in my sidebar.(see screenshot attached) I need someone to figure out how we can make the rocket take off and disappear when the user presses submit. You can either use the rocket I designed or design a new one, but keep in mind it has to be large enough for the form fields. We can use any contact form Wordpress plugin or manual code you suggest. Please provide a short description on how you would go about doing this. Thanks.
