So, 
@Yung1522 posted this awesome amazing video about the opening of IOA.  It is fantastic - there's even a commercial from the original VHS recording!   XD
There is a bit about UC researching ways to launch Hulk.  This got me wondering - why did they even have to research this?  Was it the first launched coaster?  From what I understand (very little, ba-dum-dum), it is the first (and maybe only) tire-launch coaster.  But what about LSM?  Invented after?
I know we have more than a few coaster enthusiasts on here - would love to hear more about the history behind this.
